QUICKSTART OPERATING INSTRUCTIONS
QUICKSTART OPERATING INSTRUCTIONS
This manual contains detailed operating instructions for all aspects of the flow metering instrument. The following condensed instructions assist the operator in getting the instrument running as quickly as possible. This pertains to basic operation only. Refer to the appropriate section in the manual for complete details on specific instrument features or if the installer is unfamiliar with this type of instrument.
OTE:N The following steps require information supplied by the meter itself so it will be necessary to supply power to the
unit, at least temporarily, to obtain setup information.
Transducer Location
1. In general, select a mounting location on the piping system with a minimum of ten pipe diameters (10 × the pipe inside diameter) of straight pipe upstream and ve straight diameters downstream. See Table 1 for additional congurations.
2. If the application requires DTTR, DTTN, DTTL or DTTH transducers select a mounting method for the transducers based on pipe size and liquid characteristics. See Table 2. Figure 1 illustrates the three valid transducer congurations.
OTE:N All DTTS and DTTC transducers use V–Mount configuration.
3. Enter the following data into the transmitter via the integral keypad or the software utility:
1 Transducer mounting method 7 Pipe liner thickness
2 Pipe O.D. (Outside Diameter) 8 Pipe liner material
3 Pipe wall thickness 9 Fluid type
4 Pipe material 10 Fluid sound speed*
5 Pipe sound speed* 11 Fluid viscosity*
6 Pipe relative roughness* 12 Fluid specific gravity*
OTE:N * Nominal values for these parameters are included within the flow meter operating system. The nominal values may
be used as they appear or may be modified if the exact system values are known.

INTRODUCTION
INTRODUCTION
General
This transit time ultrasonic flow meter is designed to measure the fluid velocity of liquid within a closed conduit. The transducers are a non-contacting, clamp-on type or clamp-around, which will provide benefits of non-fouling operation and ease of installation.

Figure 3: Ultrasound transmission
This family of transit time flow meters utilize two transducers that function as both ultrasonic transmitters and receivers. The transducers are clamped on the outside of a closed pipe at a specific distance from each other. The transducers can be mounted in V-Mount where the sound transverses the pipe two times, W-Mount where the sound transverses the pipe four times, or in Z-Mount where the transducers are mounted on opposite sides of the pipe and the sound crosses the pipe once. The selection of mounting method is based on pipe and liquid characteristics which both have an effect on how much signal is generated. The flow meter operates by alternately transmitting and receiving a frequency modulated burst of sound energy between the two transducers and measuring the time interval that it takes for sound to travel between the two transducers. The difference in the time interval measured is directly related to the velocity of the liquid in the pipe.
Application Versatility
This flow meter can be successfully applied on a wide range of metering applications. The simple-to-program transmitter allows the standard product to be used on pipe sizes ranging from 1/2 …100 inches (12…2540 mm)*. A variety of liquid applications can be accommodated:
ultrapure liquids cooling water potable water river water chemicals
plant effluent sewage reclaimed water others
Because the transducers are non-contacting and have no moving parts, the flow meter is not affected by system pressure, fouling or wear. Standard transducers, DTTN and DTTL are rated to a pipe surface temperature of –40…250° F (–40…121° C). DTTS small pipe transducers are rated from –40…185° F (–40…85° C). The DTTH high temperature transducers can operate to a pipe surface temperature of –40 …350° F (–40…176° C) and the DTTC small pipe high temperature transducer will withstand temperature of –40…250° F (–40…121° C).
OTE:N *All 1/2…1-1/2 in. small pipe transducers and 2 in. small pipe tubing transducer sets require the transmitter
be configured for 2 MHz and use dedicated pipe transducers. DTTL transducers require the use of the 500 kHz transmission frequency. The transmission frequency is selectable using either the software utility or the TFX Ultra keypad.
CE Compliance
The transmitter can be installed in conformance to CISPR 11 (EN 55011) standards. See the CE compliance drawings in the
APPENDIX of this manual.

TRANSMITTER INSTALLATION
TRANSMITTER INSTALLATION
After unpacking, it is recommended to save the shipping carton and packing materials in case the instrument is stored or re-shipped. Inspect the equipment and carton for damage. If there is evidence of shipping damage, notify the carrier immediately.
The enclosure should be mounted in an area that is convenient for servicing, calibration or for observation of the LCD readout.
1. Locate the transmitter within the length of transducer cables supplied. If this is not possible, it is recommended that the cable be exchanged for one that is of proper length. To add cable length to a transducer, the cable must be the same type as utilized on the transducer. Twinaxial cables can be lengthened with like cable to a maximum overall length of 100 feet (30 meters). Coaxial cables can be lengthened with RG59 75 Ohm cable and BNC connectors to 990 feet (300 meters).
2. Mount the transmitter in a location:
Where little vibration exists.
That is protected from corrosive fluids.
That is within the transmitters ambient temperature limits –40 …185° F (–40…85° C).
That is out of direct sunlight. Direct sunlight may increase transmitter temperature to above the maximum limit.

TRANSDUCER INSTALLATION
TRANSDUCER INSTALLATION
General
The transducers that are utilized by this flow meter contain piezoelectric crystals for transmitting and receiving ultrasonic signals through walls of liquid piping systems. DTTH, DTTL and DTTH transducers are relatively simple and straightforward to install, but spacing and alignment of the transducers is critical to the system’s accuracy and performance. Extra care should be taken to ensure that these instructions are carefully executed. DTTS and DTTC, small pipe transducers, have integrated transmitter and receiver elements that eliminate the requirement for spacing measurement and alignment.
Mounting of the DTTN, DTTL, and DTTH clamp-on ultrasonic transit time transducers is comprised of three steps:
1. Selection of the optimum location on a piping system.
2. Entering the pipe and liquid parameters into either the software utility or keying the parameters into transmitter using the keypad. The software utility or the transmitters rmware will calculate proper transducer spacing based on these entries.
3. Pipe preparation and transducer mounting.
Energy transmitters require two RTDs to measure heat usage. The flow meter utilizes 1000 Ohm, three-wire, platinum RTDs in two mounting styles. Surface mount RTDs are available for use on well insulated pipes. If the area where the RTD will be located is not insulated, inconsistent temperature readings will result and insertion (wetted) RTDs should be utilized.
Step 1 – Mounting location
The first step in the installation process is the selection of an optimum location for the flow measurement to be made. For this to be done effectively, a basic knowledge of the piping system and its plumbing are required.
An optimum location is defined as:
A piping system that is completely full of liquid when measurements are being taken. The pipe may become completely empty during a process cycle – which will result in the error code 0010 (Low Signal Strength) being displayed on the flow meter while the pipe is empty. This error code will clear automatically once the pipe refills with liquid. It is not recommended to mount the transducers in an area where the pipe may become partially filled. Partially filled pipes will cause erroneous and unpredictable operation of the meter.
A piping system that contains lengths of straight pipe such as those described in Table 1. The optimum straight pipe diameter recommendations apply to pipes in both horizontal and vertical orientation. The straight runs in Table 1 apply to liquid velocities that are nominally 7 fps (2.2 mps). As liquid velocity increases above this nominal rate, the requirement for straight pipe increases proportionally.
Mount the transducers in an area where they will not be inadvertently bumped or disturbed during normal operation.
Avoid installations on downward flowing pipes unless adequate downstream head pressure is present to overcome partial filling of or cavitation in the pipe.

TRANSDUCER INSTALLATION
Step 2 – Transducer Spacing
The transmitter can be used with five different transducer types: DTTN, DTTL, DTTH, DTTS and DTTC. Meters that utilize the DTTN, DTTL or DTTH, transducer sets consist of two separate sensors that function as both ultrasonic transmitters and receivers. DTTS and DTTC transducers integrate both the transmitter and receiver into one assembly that fixes the separation of the piezoelectric crystals. DTTN, DTTL and DTTH transducers are clamped on the outside of a closed pipe at a specific distance from each other.
The DTTN, DTTL and DTTH transducers can be mounted in:
W-Mount where the sound traverses the pipe four times. This mounting method produces the best relative travel time values but the weakest signal strength.
V-Mount where the sound traverses the pipe twice. V-Mount is a compromise between travel time and signal strength.
Z-Mount where the transducers are mounted on opposite sides of the pipe and the sound crosses the pipe once. Z-Mount will yield the best signal strength but the smallest relative travel time.

For further details, reference Figure 9. The appropriate mounting configuration is based on pipe and liquid characteristics. Selection of the proper transducer mounting method is not entirely predictable and many times is an iterative process.
Table 2 contains recommended mounting configurations for common applications. These recommended configurations may
need to be modified for specific applications if such things as aeration, suspended solids, out of round piping or poor piping conditions are present. Use of the flow meter diagnostics in determining the optimum transducer mounting is covered later in this section.

For pipes 24 inch (600 mm) and larger the DTTL transducers using a transmission frequency of 500 kHz are recommended.
DTTL transducers may also be advantageous on pipes between 4…24 inches if there are less quantifiable complicating aspects such as – sludge, tuberculation, scale, rubber liners, plastic liners, thick mortar, gas bubbles, suspended solids, emulsions, or pipes that are perhaps partially buried where a V-mount is required/desired, etc.

TRANSDUCER INSTALLATION
Step 3 – Entering Pipe and Liquid Data
This metering system calculates proper transducer spacing by utilizing piping and liquid information entered by the user. This information can be entered via the keypad on the flow meter or via the optional software utility.
The best accuracy is achieved when transducer spacing is exactly what the flow meter calculates, so the calculated spacing should be used if signal strength is satisfactory. If the pipe is not round, the wall thickness not correct or the actual liquid being measured has a different sound speed than the liquid programmed into the transmitter, the spacing can vary from the calculated value. If that is the case, the transducers should be placed at the highest signal level observed by moving the transducers slowly around the mount area.
OTE:N Transducer spacing is calculated on “ideal” pipe. Ideal pipe is almost never found so the transducer spacing distances
may need to be altered. An effective way to maximize signal strength is to configure the display to show signal strength, fix one transducer on the pipe and then starting at the calculated spacing, move the remaining transducer small distances forward and back to find the maximum signal strength point.
MPORTANTI
Enter all of the data on this list, save the data and reset the flow meter before mounting transducers.
The following information is required before programming the instrument:
Transducer mounting configuration Pipe O.D. (outside diameter)
Pipe wall thickness Pipe material
Pipe sound speed

Pipe relative roughness
Pipe liner thickness (if present) Pipe liner material (if present)
Fluid type Fluid sound speed

OTE:N Much of the data relating to material sound speed, viscosity and specific gravity is pre-programmed into the flow
meter. This data only needs to be modified if it is known that a particular application’s data varies from the reference values. Refer to STARTUP and CONFIGURATION of this manual for instructions on entering configuration data into the flow meter via the transmitter’s keypad. Refer to INPUTS/OUTPUTS for data entry via the software.

Nominal values for these parameters are included within the meters operating system. The nominal values may be used as
they appear or may be modified if exact system values are known.
After entering the data listed above, the flow meter will calculate proper transducer spacing for the particular data set. This distance will be in inches if the flow meter is configured in English units, or millimeters if configured in metric units.

Step 4 – Transducer Mounting
Pipe Preparation
After selecting an optimal mounting location (Step 1) and successfully determining the proper transducer spacing (Step 2 & 3), the transducers may now be mounted onto the pipe (Step 4).
Before the transducers are mounted onto the pipe surface, an area slightly larger than the flat surface of each transducer must be cleaned of all rust, scale and moisture. For pipes with rough surfaces, such as ductile iron pipe, it is recommended that the pipe surface be wire brushed to a shiny finish. Paint and other coatings, if not flaked or bubbled, need not be removed. Plastic pipes typically do not require surface preparation other than soap and water cleaning.
The DTTN, DTTL, and DTTH transducers must be properly oriented and spaced on the pipe to provide optimum reliability and performance. On horizontal pipes, when Z-Mount is required, the transducers should be mounted 180 radial degrees from one another and at least 45 degrees from the top-dead-center and bottom-dead-center of the pipe. See Figure 10. Also see Z-Mount Transducer Installation. On vertical pipes the orientation is not critical.
The spacing between the transducers is measured between the two spacing marks on the sides of the transducers. These marks are approximately 0.75 inches (19 mm) back from the nose of the DTTN and DTTH transducers, and 1.2 inches (30 mm) back from the nose of the DTTL transducers. See Figure 11.
DTTS and DTTC transducers should be mounted with the cable exiting within ±45 degrees of the side of a horizontal pipe. See
Figure 10. On vertical pipes the orientation does not apply.

Application of Couplant
For DTTN, DTTL, and DTTH transducers, place a single bead of couplant, approximately 1/2 inch (12 mm) thick, on the flat face of the transducer. See Figure 12. Generally, a silicone-based grease is used as an acoustic couplant, but any grease-like substance that is rated not to “flow” at the temperature that the pipe may operate at will be acceptable. For pipe surface temperature over 130° F (55° C), Sonotemp® (P.N. D002-2011-010) is recommended.

Transducer Positioning
1. Place the upstream transducer in position and secure with a mounting strap. Straps should be placed in the arched groove on the end of the transducer. A screw is provided to help hold the transducer onto the strap. Verify that the transducer is true to the pipe and adjust as necessary. Tighten the transducer strap securely.
2. Place the downstream transducer on the pipe at the calculated transducer spacing. See Figure 13. Apply rm hand pressure. If signal strength is greater than ve, secure the transducer at this location. If the signal strength is not 5 or greater, using rm hand pressure slowly move the transducer both towards and away from the upstream transducer while observing signal strength. Signal strength can be displayed on the ow meter’s display or on the main data screen in the software utility. See Part ve of this manual for details regarding the software utility. Clamp the transducer at the position where the highest signal strength is observed. The factory default signal strength setting is ve, however there are many application specic conditions that may prevent the signal strength from attaining this level. Signal levels less than ve will probably not be acceptable for reliable readings.
OTE:N Signal strength readings update only every few seconds, so it is advisable to move the transducer 1/8 inch, wait, see if
signal is increasing or decreasing and then repeat until the highest level is achieved.
3. If after adjustment of the transducers the signal strength does not rise to above ve, then an alternate transducer mounting method should be selected. If the mounting method was W-Mount, then re-congure the transmitter for
V-Mount, move the downstream transducer to the new spacing distance and repeat Step 4.
OTE:N Mounting of high temperature transducers is similar to
mounting the DTTN/DTTL transducers. High temperature installations require acoustic couplant that is rated not to “flow” at the temperature that will be present on the pipe surface.
OTE:N As a rule, the DTTL should be used on pipes 24 inches and larger
and not used for application on a pipe smaller than 4 inches. Consider application of the DTTL transducers on pipes smaller than 24 inches if there are less quantifiable aspects such as – sludge, tuberculation, scale, rubber liners, plastic liners, thick mortar liners, gas bubbles, suspended solids, emulsions, and smaller pipes that are perhaps partially buried where a V-Mount is required or desired.

DTTS/DTTC Small Pipe Transducer Installation
The small pipe transducers are designed for specific pipe outside diameters. Do not attempt to mount a DTTS/DTTC transducer onto a pipe that is either too large or too small for the transducer. Contact the manufacturer to arrange for a replacement transducer that is the correct size.
DTTS/DTTC installation consists of the following steps:
1. Apply a thin coating of acoustic coupling grease to both halves of the transducer housing where the housing will contact the pipe. See Figure 14.
2. On horizontal pipes, mount the transducer in an orientation such that the cable exits at ±45 degrees from the side of the pipe. Do not mount with the cable exiting on either the top or bottom of the pipe. On vertical pipes the orientation does
not matter. See Figure 10.
3. Tighten the wing nuts or U-bolts so that the acoustic coupling grease begins to ow out from the edges of the transducer or from the gap between the transducer halves. Do not over tighten.
4. If signal strength is less than 5, remount the transducer at another location on the piping system.

Mounting Transducers in Z-Mount Conguration
Installation on larger pipes requires careful measurements of the linear and radial placement of the DTTN, DTTL, and DTTH transducers. Failure to properly orient and place the transducers on the pipe may lead to weak signal strength and/or inaccurate readings. This section details a method for properly locating the transducers on larger pipes. This method requires a roll of paper such as freezer paper or wrapping paper, masking tape and a marking device.
1. Wrap the paper around the pipe in the manner shown in Figure 19. Align the paper ends to within 1/4 inch (6 mm).
2. Mark the intersection of the two ends of the paper to indicate the circumference. Remove the template and spread it out on a at surface. Fold the template in half, bisecting the circumference. See Figure 20.
3. Crease the paper at the fold line. Mark the crease. Place a mark on the pipe where one of the transducers will be located. See Figure 10 for acceptable radial orientations. Wrap the template back around the pipe, placing the beginning of the
paper and one corner in the location of the mark. Move to the other side of the pipe and mark the pipe at the ends of the crease. Measure from the end of the crease (directly across the pipe from the rst transducer location) the dimension derived in Step 2, Transducer Spacing. Mark this location on the pipe.
Page 25 March 2014
VMOUNT AND WMOUNT INSTALLATION
4. The two marks on the pipe are now properly aligned and measured. If access to the bottom of the pipe prohibits the wrapping of the paper around the circumference, cut a piece of paper 1/2 the circumference of the pipe and lay it over the top of the pipe. The length of 1/2 the circumference can be found by:
½ Circumference = Pipe O.D. × 1.57
The transducer spacing is the same as found in the Transducer Positioning section. Mark opposite corners of the paper on the pipe. Apply transducers to these two marks.

5. For DTTN, DTTL, and DTTH transducers, place a single bead of couplant, approximately 1/2 inch (12 mm) thick,
on the at face of the transducer. See Figure 12. Generally, a silicone-based grease is used as an acoustic couplant, but any good quality grease-like substance that is rated to not ow at the temperature that the pipe may operate at will be acceptable.
6. Place the upstream transducer in position and secure with a stainless steel strap or other fastening device. Straps should be placed in the arched groove on the end of the transducer. A screw is provided to help hold the transducer onto the strap. Verify that the transducer is true to the pipe, adjust as necessary. Tighten transducer strap securely. Larger pipes may require more than one strap to reach the circumference of the pipe.
7. Place the downstream transducer on the pipe at the calculated transducer spacing. See Figure 21. Using rm
hand pressure, slowly move the transducer both towards and away from the upstream transducer while observing signal strength. Clamp the transducer at the position where the highest signal strength is observed. Signal strength of between 5…98 is acceptable. The factory default signal strength setting is 5, however there are many application specic conditions that may prevent the signal strength from attaining this level

8. A minimum signal strength of 5 is acceptable as long as this signal level is maintained under all ow conditions.
On certain pipes, a slight twist to the transducer may cause signal strength to rise to acceptable levels. Certain pipe and liquid characteristics may cause signal strength to rise to greater than 98. The problem with operating this meter with very high signal strength is that the signals may saturate the input ampliers and cause erratic readings. Strategies for lowering signal strength would be changing the transducer mounting method to the next longest transmission path. For example, if there is excessive signal strength and the transducers are mounted in a Z-Mount, try changing to V-Mount or W-Mount. Finally you can also move one transducer slightly o line with the other transducer to lower signal strength.
9. Secure the transducer with a stainless steel strap or other fastener.
Mounting Track Installation
1. A convenient transducer mounting track can be used for pipes that have outside diameters between two and ten inches
(50 … 250 mm). If the pipe is outside of that range, select a V-Mount or Z-Mount mounting method.
2. Install the single mounting rail on the side of the pipe with the stainless steel bands provided. Do not mount it on the top
or bottom of the pipe. Orientation on vertical pipe is not critical. Ensure that the track is parallel to the pipe and that all four mounting feet are touching the pipe.
3. Slide the two transducer clamp brackets towards the center mark on the mounting rail.
4. Place a single bead of couplant, approximately 1/2 inch (12 mm) thick, on the at face of the transducer. See Figure 12.
5. Place the rst transducer in between the mounting rails near the zero point on the scale. Slide the clamp over the
transducer. Adjust the clamp/transducer such that the notch in the clamp aligns with zero on the scale. See Figure 22.
6. Secure with the thumb screw. Ensure that the screw rests in the counter bore on the top of the transducer. (Excessive
pressure is not required. Apply just enough pressure so that the couplant lls the gap between the pipe and transducer.)
7. Place the second transducer in between the mounting rails near the dimension derived in the transducer spacing section.
Read the dimension on the mounting rail scale. Slide the transducer clamp over the transducer and secure with the thumb screw.

INPUTS/OUTPUTS
INPUTS/OUTPUTS
General
The flow metering system is available in two general configurations. There is the standard flow meter model that is equipped with a 4-20 mA output, two open collector outputs, a rate frequency output, and RS485 communications using the Modbus RTU command set.
The energy version of the flow metering family has inputs for two 1000 Ohm RTD sensors in place of the rate frequency and alarm outputs. This version allows the measurement of pipe input and output temperatures so energy usage calculations can be performed.
4-20 mA Output
The 4-20 mA output interfaces with most recording and logging systems by transmitting an analog current signal that is proportional to system flow rate. The 4-20 mA output is internally powered (current sourcing) and can span negative to positive flow/energy rates.
For AC powered units, the 4-20 mA output is driven from a 15V DC source located within the meter. The source is isolated from earth ground connections within the flow meter. The AC powered model can accommodate loop loads up to 400 Ohms. DC powered meters utilize the DC power supply voltage to drive the current loop. The current loop is not isolated from DC ground or power. Figure 23 shows graphically the allowable loads for various input voltages. The combination of input voltage and loop load must stay within the shaded area of Figure 23.

The flow rate output permits output changeover at two separate flow rates allowing operation with an adjustable switch deadband. Figure 27 illustrates how the setting of the two set points influences rate alarm operation.
A single-point flow rate alarm would place the ON setting slightly higher than the OFF setting allowing a switch deadband to be established. If a deadband is not established, switch chatter (rapid switching) may result if the flow rate is very close to the switch point.

Batch/Totalizer Output for Flow Only Version
Totalizer mode configures the output to send a 100 mSec pulse each time the display totalizer increments divided by the TOT MULT. The TOT MULT value must be a whole, positive, numerical value. This output is limited to 1 Hz maximum.
For example, if the totalizer exponent TOTL E is set to E0 ×1 and the totalizer multiplier TOT MULT is set to 1, then the output will pulse each time the totalizer increments one count, or each single, whole measurement unit totalized.
If the totalizer exponent TOTL E is set to E2 ×100 and the totalizer multiplier TOT MULT is set to 1, then the control output will pulse each time the display totalizer increments or once per 100 measurement units totalized.
If the totalizer exponent TOTL E is set to E0 ×1 and the totalizer multiplier TOT MULT is set to 2, the control output will pulse once for every two counts that the totalizer increments.

Energy units can be ordered with a totalizer pulse output option. This option is installed in the position where the Ethernet option would normally be installed.

Signal Strength Alarm
The SIG STR alarm will provide an indication that the signal level reported by the transducers has fallen to a point where flow measurements may not be possible. It can also be used to indicate that the pipe has emptied. Like the rate alarm described previously, the signal strength alarm requires that two points be entered, establishing an alarm deadband. A valid switch point exists when the ON value is lower than the OFF value. If a deadband is not established and the signal strength decreases to approximately the value of the switch point, the output may “chatter”.
Error Alarm Outputs
When a control output is set to ERROR mode, the output will activate when any error occurs in the flow meter that has caused the meter to stop measuring reliably. See the APPENDIX of this manual for a list of potential error codes.

ALARM OUTPUTS
Frequency Output [Flow Only Models]
The frequency output is an open-collector transistor circuit that outputs a pulse waveform that varies proportionally with flow rate. This type of frequency output is also know as a “Rate Pulse” output. The output spans from 0 Hz, normally at zero flow rate to 1000 Hz at full flow rate (configuration of the MAX RATE parameter is described in detail in the flow meter configuration section of this manual).

If, for example, the MAX RATE parameter was set to 400 gpm then an output frequency of 500 Hz (half of the full scale frequency of 1000 Hz) would represent 200 gpm.
In addition to the control outputs, the frequency output can be used to provide total information by use of a K factor. A K factor simply relates the number of pulses from the frequency output to the number of accumulated pulses that equates to a specific volume.
For this meter the relationship is described by the following equation. The 60,000 relates to measurement units in volume/ min. Measurement units in seconds, hours or days would require a different numerator.

A practical example would be if the MAX RATE for the application were 400 gpm, the K factor (representing the number of pulses accumulated needed to equal one gallon) would be:
K factor

Pulses Per Gallon
If the frequency output is to be used as a totalizing output, the flow meter and the receiving instrument must have identical K factor values programmed into them to ensure that accurate readings are being recorded by the receiving instrument. Unlike standard mechanical flow meters such as turbines, gear or nutating disk meters, the K factor can be changed by modifying the MAX RATE flow rate value.
OTE:N For a full treatment of K factors please see the APPENDIX of this manual.
There are two frequency output types available:
1. Turbine meter simulation – This option is utilized when a receiving instrument is capable of interfacing directly with a turbine ow meter’s magnetic pickup. The output is a relatively low voltage AC signal whose amplitude swings above and below the signal ground reference. The minimum AC amplitude is approximately 500 mV peak-to-peak. To activate the turbine output circuit, turn SW4 OFF.

2. Square-wave frequency – This option is utilized when a receiving instrument requires that the pulse voltage level be either of a higher potential and/or referenced to DC ground. The output is a square-wave with a peak voltage equaling the instrument supply voltage when the SW3 is ON. If desired, an external pullup resistor and power source can be utilized by leaving SW3 OFF. Set SW4 to ON for a square-wave output.

RS485
The RS485 feature allows up to 126 flow metering systems to be placed on a single three-wire cable bus. All meters are assigned a unique numeric address that allows all of the meters on the cable network to be independently accessed. A Modbus RTU command protocol is used to interrogate the meters. An explanation of the command structure is detailed in the Appendix of this manual. Flow rate, total, signal strength and temperature (if so equipped) can be monitored over the digital communications bus. Baud rates up to 9600 and cable lengths to 5000 feet (1500 meters) are supported without repeaters or “end of line” resistors.
To interconnect meters, utilize three-wire shielded cable such as Belden 9939 or equal. In noisy environments the shield should be connected on one end to a good earth ground connection. A USB to RS485 converter such as the B & B Electronics P/N 485USBTB-2W can be used to communicate with a PC running Windows 98, Windows ME, Windows 2000, Windows NT, Windows XP, Windows Vista, and Windows 7. For computers with RS232C serial ports, an RS232C to RS485 converter, such as B&B Electronics P/N 485SD9TB (illustrated in Figure 32), is required to interconnect the RS485 network to a communication port on a PC. If more than 126 meters must be monitored, an additional converter and communication port are required.
OTE:N When USB programming cable is connected, the RS485 and frequency outputs are disabled.

HEAT FLOW FOR ENERGY MODELS ONLY
HEAT FLOW FOR ENERGY MODELS ONLY
The energy version allows the integration of two 1000 Ohm, platinum RTDs with the flow meter, effectively providing an instrument for measuring energy consumed in liquid heating and cooling systems. If RTDs were ordered with the energy version of the flow meter, they have been factory calibrated and are shipped with the meter.
The energy meter has multiple heat ranges to choose from. For best resolution use the temperature range that encompasses the temperature range of the application.
The three-wire surface mount RTDs are attached at the factory to a simple plug-in connector eliminating the possibility of mis-wiring. Simply install the RTDs on or in the pipe as recommended, and then plug the RTDs into the RTD connector in the flow meter.
Four ranges of surface mount RTDs and two lengths of wetted insertion probes are offered. Other cable lengths for surface mount RTDs are available. Contact the manufacturer for additional offerings.
All RTDs are 1000 Ohm platinum, three-wire devices. The surface mount versions are available in standard lengths of 20 feet (6 meters), 50 feet (15 meters) and 100 feet (30 meters) of attached shielded cable.
Installation of Surface Mounted RTD’S
Surface mount RTDs should only be utilized on well insulated pipe. If the area where the RTD is located is not insulated, inconsistent temperature readings will result. Insertion (wetted) RTDs should be used on pipes that are not insulated.
Select areas on the supply and return pipes where the RTDs will be mounted. Remove or peel back the insulation all the way around the pipe in the installation area. Clean an area slightly larger than the RTD down to bare metal on the pipe.
Place a small amount of heat sink compound on the pipe in the RTD installation location. See Figure 3.12. Press the RTD firmly into the compound. Fasten the RTD to the pipe with the included stretch tape.
Route the RTD cables back to the flow meter and secure the cable so that it will not be pulled on or abraded inadvertently. Replace the insulation on the pipe, ensuring that the RTDs are not exposed to air currents.

INSTALLATION OF INSERTION RTD’S
Insertion RTDs are typically installed through 1/4 inch (6 mm) compression fittings and isolation ball valves. Insert the RTD sufficiently into the flow stream such that a minimum of 1/4 inch (6 mm) of the probe tip extends into the pipe diameter.
RTDs should be mounted within ±45 degrees of the side of a horizontal pipe. On vertical pipes the orientation is not critical. Route the RTD cables back to the flow meter and secure the cable so that it will not be pulled on or abraded inadvertently.
If the cables are not long enough to reach the flow meter route the cables to an electrical junction box and add additional cable from that point. Use three-wire shielded cable, such as Belden® 9939 or equal, for this purpose.
OTE:N Adding cable adds to the resistance the meter reads
and may have an effect on absolute accuracy. If cable is added, ensure that the same length is added to both RTDs to minimize errors due to changes in cable resistance.
INSTALLATION OF INSERTION RTD’S
WIRING TO METER
Figure 35: Insertion style RTD installation
After the RTDs have been mounted to the pipe, route the cable back to the flow meter through the middle hole in the enclosure. Connection to the meter is accomplished by inserting the RTD connector into the mating connector on the circuit board. Be sure that the alignment tab on the RTD cable is up.

STARTUP AND CONFIGURATION
STARTUP AND CONFIGURATION
Before Starting the Instrument
OTE:N This flow metering system requires a full pipe of liquid before a successful start-up can be completed. Do not attempt
to make adjustments or change configurations until a full pipe is verified.
OTE:N If Dow 732 RTV was utilized to couple the transducers to the pipe, the adhesive must be fully cured before readings
are attempted. Dow 732 requires 24 hours to cure satisfactorily. If Sonotemp® acoustic coupling grease was utilized as a couplant, curing is not required.
Instrument Startup
Procedure:
1. Verify that all wiring is properly connected and routed, as described in TRANSMITTER INSTALLATION of this manual.
2. Verify that the transducers are properly mounted, as described in TRANSDUCER INSTALLATION of this manual.
3. Apply power. The display of the ow meter will briey show a software version number and then all of the segments will illuminate in succession.
OTE:N In order to complete the installation of the flow meter, the pipe must be full of liquid.
To verify proper installation and flow measurement operation:
1. Go to the SER MENU and conrm that signal strength SIG STR is between 5…98. If the signal strength is lower than ve, verify that proper transducer mounting methods and liquid/pipe characteristics have been entered. To increase signal strength, if a W-Mount transducer installation was selected, re-congure for a V-Mount installation; if V-Mount was selected, re-congure for Z-Mount.
OTE:N Mounting configuration changes apply only to DTTN, DTTL and DTTH transducer sets.
2. Verify that the actual measured liquid sound speed is very close to the expected value. The measured liquid sound speed (SSPD fps and SSPD mps) is displayed in the SER MENU. Verify that the measured sound speed is within two percent of the value entered as FLUID SS in the BSC MENU. The pipe must be full of liquid in order to make this measurement.
Once the meter is operating properly, refer to the KEYPAD PROGRAMMING section of this manual for additional programming features.
Page 37 March 2014
KEYPAD PROGRAMMING
KEYPAD PROGRAMMING
A meter ordered with a keypad can be configured through the keypad interface or by using the Windows® compatible software utility. Units without a keypad can only be configured using the software utility. See SOFTWARE UTILITY of this manual for software details. Of the two methods of configuration, the software utility provides more advanced features and offers the ability to store and transfer meter configurations between like flow meters. All entries are saved in non-volatile FLASH memory and will be retained indefinitely in the event of power loss.
OTE:N When USB programming cable is connected, the RS485 and frequency outputs are disabled.
The flow meter versions with a keypad contain a four-key tactile feedback keypad interface that allows the user to view and change configuration parameters used by the operating system.

Fluid Viscosity
FLUID VI — Absolute Viscosity of the Fluid (Value - cP)
Allows adjustments to be made to the absolute viscosity of the liquid in centipoise.
Ultrasonic flow meters utilize pipe size, viscosity and specific gravity to calculate Reynolds numbers. Since the Reynolds number influences flow profile, the flow meter has to compensate for the relatively high velocities at the pipe center during transitional or laminar flow conditions. The entry of FLUID VI is utilized in the calculation of Reynolds and the resultant compensation values.
If a fluid was chosen from the FL TYPE list, a nominal value for viscosity in that media will be automatically loaded. If the actual viscosity is known for the application fluid and that value varies from the automatically loaded value, the value can be revised.

TOTL E — Flow Totalizer Exponent Value (Choice)
E(–1)E6
Utilized for setting the flow totalizer exponent. This feature is useful for accommodating a very large accumulated flow or to increase totalizer resolution when flows are small (displaying fractions of whole barrels, gallons, etc.) The exponent is a × 10n multiplier, where “n” can be from –1 (× 0.1)…6 (× 1000,000).
Table 8 should be referenced for valid entries and their influence on the display.
Selection of E-1 and E0 adjusts the decimal point on the display. Selection of E1, E2 and E3 causes an icon of × 10, × 100 or × 1000 respectively to appear to the right of the total flow display value.

Minimum Flow Rate
MIN RATE — Minimum Flow Rate Settings (Value)
A minimum rate setting is entered to establish filter software settings and the lowest rate value that will be displayed. Volumetric entries will be in the rate units and interval selected previousley. For unidirectional measurements, set MIN RATE to zero. For bidirectional measurements, set MIN RATE to the highest negative (reverse) flow rate expected in the piping system.
OTE:N The flow meter will not display a flow rate at flows less than the MIN RATE value. As a result, if the MIN RATE is set to a
value greater than zero, the flow meter will display the MIN RATE value, even if the actual flow/energy rate is less than the MIN RATE.
For example, if the MIN RATE is set to 25 and actual rate is 0, the meter display will indicate 25. Another example, if the
MIN RATE is set to -100 and the actual flow is -200, the meter will indicate -100. This can be a problem if the meter MIN RATE is set to a value greater than zero because at flows below the MIN RATE the rate display will show zero flow, but the totalizer which is not affected by the MIN RATE setting will keep totalizing.
Maximum Flow Rate
MAX RATE — Maximum Flow Rate Settings (Value)
A maximum volumetric flow rate setting is entered to establish filter software settings. Volumetric entries will be in the rate units and Interval selected previousley. For unidirectional measurements, set MAX RATE to the highest (positive) flow rate expected in the piping system. For bidirectional measurements, set MAX RATE to the highest (positive) flow rate expected in the piping system.

Low Flow Cut-off
FL C-OFF — Low Flow Cut-off (Value)
0…100%
A low flow cut-off entry is provided to allow very low flow rates (that can be present when pumps are off and valves are closed) to be displayed as zero flow. Typical values that should be entered are between 1.0% and 5.0% of the flow range between MIN RATE and MAX RAT E.
Damping Percentage
DAMP PER — System Damping (Value)
0…100%
Flow filter damping establishes a maximum adaptive filter value. Under stable flow conditions (flow varies less than 10% of reading), this adaptive filter will increase the number of successive flow readings that are averaged together up to this maximum value. If flow changes outside of the 10% window, the flow filter adapts by decreasing the number of averaged readings which allows the meter to react faster. Increasing this value tends to provide smoother steady-state flow readings and outputs. If very erratic flow conditions are present or expected, other filters are available for use in the software utility. See
SOFTWARE UTILITY of this manual for further information.

FL 4MA Flow at 4 mA
FL 20MA Flow at 20 mA
CAL 4MA 4 mA Calibration
CAL 20MA 20 mA Calibration
4-20 TST 4-20 mA Test
The CH1 menu controls how the 4-20 mA output is spanned for all flow meter models and how the frequency output is spanned for the flow only model.
The FL 4MA and FL 20MA settings are used to set the span for both the 4-20 mA output and the 0…1000 Hz frequency output on the flow only meter versions.
The 4-20 mA output is internally powered (current sourcing) and can span negative to positive flow/energy rates. This output interfaces with virtually all recording and logging systems by transmitting an analog current that is proportional to system flow rate. Independent 4 mA and 20 mA span settings are established in firmware using the flow measuring range entries. These entries can be set anywhere in the –40…40 fps (–12…12 mps) range of the instrument. Resolution of the output is 12-bits (4096 discrete points) and the can drive up to a 400 Ohm load when the meter is AC powered. When powered by a DC supply, the load is limited by the input voltage supplied to the instrument. See Figure 23 for allowable loop loads.
FL 4MA — Flow at 4 mA
FL 20MA — Flow at 20 mA
The FL 4MA and FL 20MA entries are used to set the span of the 4-20 mA analog output and the frequency output on flow only versions. These entries are volumetric rate units that are equal to the volumetric units configured as RATE UNT and RATE INT discussed previousley.
For example, to span the 4-20 mA output from –100…100 gpm, with 12 mA being 0 gpm, set the FL 4MA and FL 20MA inputs as follows:
FL 4MA = –100.0
FL 20MA = 100.0
If the meter were a flow only model, this setting would also set the span for the frequency output. At –100 gpm, the output frequency would be 0 Hz. At the maximum flow of 100 gpm, the output frequency would be 1000 Hz, and in this instance a flow of zero would be represented by an output frequency of 500 Hz.
Page 46 March 2014
BSC MENU  BASIC MENU
Example 2 – To span the 4-20 mA output from 0…100 gpm, with 12 mA being 50 gpm, set the FL 4MA and FL 20MA inputs as follows:
FL 4MA = 0.0
FL 20MA = 100.0
For the flow only unit, in this instance zero flow would be represented by 0 Hz and 4 mA. The full scale flow or 100 gpm would be 1000 Hz and 20 mA, and a midrange flow of 50 gpm would be expressed as 500 Hz and 12 mA.
The 4-20 mA output is factory calibrated and should not require adjustment. If small adjustments to the DAC (Digital to Analog Converter) are needed, for instance if adjustment due to the accumulation of line losses from long output cable lengths are required, the CAL 4mA and CAL 20 MA can be used.
CAL 4 MA — 4 mA DAC Calibration Entry (Value)
CAL 20 MA— 20 mA DAC Calibration Entry (Value)
The CAL 4MA and CAL 20 MA entries allow fine adjustments to be made to the zero and full scale of the 4-20 mA output. To adjust the outputs, an ammeter or reliable reference connection to the 4-20 mA output must be present.
OTE:N Calibration of the 20 mA setting is conducted much the same way as the 4 mA adjustments. OTE:N The CAL 4MA and CAL 20MA entries should not be used in an attempt to set the 4-20 mA range. Utilize FL 4MA and
FL 20MA, detailed above, for this purpose.
4 mA Calibration Procedure:
1. Disconnect one side of the current loop and connect the ammeter in series (disconnect either wire at the terminals labeled 4-20 mA Out or Signal Gnd).
2. Using the arrow keys, increase the numerical value to increase the current in the loop to 4 mA. Decrease the value to decrease the current in the loop to 4 mA. Typical values range between 40…80 counts.
3. Reconnect the 4-20 mA output circuitry as required.
20 mA Calibration Procedure:
1. Disconnect one side of the current loop and connect the ammeter in series (disconnect either wire at the terminals labeled 4-20 mA Out or Signal Gnd).
2. Using the arrow keys, increase the numerical value to increase the current in the loop to 20 mA. Decrease the value to decrease the current in the loop to 20 mA. Typical values range between 3700…3900 counts.
3. Reconnect the 4-20 mA output circuitry as required.
4-20 TST — 4-20 mA Output Test (Value)
Allows a simulated flow value to be sent from the 4-20 mA output. By incrementing this value, the 4-20 mA output will transmit the indicated current value.

Inputs from two 1000 Ohm platinum RTD temperature sensors allow measurements of heating or cooling usage.
The values used to calibrate the RTD temperature sensors are derived in the laboratory and are specific to the RTD and to the electronic circuit it is connected to. The RTDs on new units come with the calibration values already entered into the energy meter and should not need to be changed.
Field replacement of RTDs is possible thru the use of the keypad or the software utility. If the RTDs were ordered from the manufacturer, they will come with calibration values that need to be loaded into the energy meter.
New, non-calibrated RTDs will need to be field calibrated using an ice bath and boiling water to derive calibration values. This procedure is outlined in the APPENDIX of this manual.

SSPD mps — Liquid Sound Speed (Meters per Second) (Reported by Firmware)
SSPD fps — Liquid Sound Speed (Feet per Second) (Reported by Firmware)
The flow meter performs an actual speed of sound calculation for the liquid it is measuring. This speed of sound calculation will vary with temperature, pressure and fluid composition.
The meter will compensate for fluid sound speeds that vary within a window of ± 10% of the liquid specified in the BSC MENU. If this range is exceeded, error code 0011 will appear on the display and the sound speed entry must be corrected.
The value indicated in SSPD measurement should be within 10% of the value entered/indicated in the BSC MENU item
FLUID SS. (The SSPD value itself cannot be edited.) If the actual measured value is significantly different (> ± 10%) than the BSC MENU’s FLUID SS value, it typically indicates a problem with the instrument setup. An entry such as FL TYPE, PIPE OD or PIPE WT may be in error, the pipe may not be round or the transducer spacing is not correct.
Table 10 lists sound speed values for water at varying temperatures. If the meter is measuring sound speed within 2% of the
table values, then the installation and setup of the instrument is correct.

SIG STR — Signal Strength (Reported by Firmware)
The SIG STR value is a relative indication of the amount of ultrasound making it from the transmitting transducer to the receiving transducer. The signal strength is a blending of esoteric transit time measurements distilled into a usable overall reference.
The measurement of signal strength assists service personnel in troubleshooting the flow meter system. In general, expect the signal strength readings to be greater than five on a full pipe with the transducers properly mounted. Signal strength readings that are less than five indicate a need to choose an alternative mounting method for the transducers or that an improper pipe size has been entered.
Signal strength below the low signal cutoff SIG C-OF value will generate a 0010 error (Low Signal Strength) and require either a change in the SIG C-OF value or transducer mounting changes.
Page 50 March 2014
SER MENU  SERVICE MENU
OTE:N If the unit is configured to display totalizer values, the display will alternate between error 0010 and the
totalizer value.
Signal strength readings in excess of 98 may indicate that a mounting method with a longer path length may be required. For example, if transducers mounted on a 3 inch PVC pipe in V-Mount cause the measured signal strength value to exceed 98, change the mounting method to W-Mount for greater stability in readings.
Because signal strength is not an absolute indication of how well a meter is functioning, there is no real advantage to a signal strength of 50 over a signal strength of 10.
TEMP 1 — Temperature of RTD 1 (Reported by Firmware in °C)
When RTD is selected from the CH2 menu and RTDs are connected to the energy meter, the firmware will display the temperature measured by RTD 1 in ° C.
TEMP 2 — Temperature of RTD 2 (Reported by Firmware in °C)
When RTD is selected from the CH2 menu and RTDs are connected to the energy meter, the firmware will display the temperature measured by RTD 2 in ° C.
TEMPDIFF — Temperature difference (Reported by Firmware in °C)
When RTD is selected from the CH2 menu and RTDs are connected to the energy meter, the firmware will display the difference in temperature measured between RTD 1 and RTD 2 in ° C.
SIG C-OF — Low Signal Cutoff (Value)
0.0…100.0
The SIG C-OF is used to drive the flow meter and its outputs to the SUB FLOW (Substitute Flow described below) state if conditions occur that cause low signal strength. A signal strength indication below 5 is generally inadequate for measuring flow reliably, so the minimum setting for SIG C-OF is 5. A good practice is to set the SIG C-OF at approximately 60…70% of actual measured maximum signal strength.
OTE:N The factory default Signal Strength Cutoff is 5.
If the measured signal strength is lower than the SIG C-OF setting, an error 0010 will be shown on the flow meters display until the measured signal strength becomes greater than the cutoff value.
A signal strength indication below 2 is considered to be no signal at all. Verify that the pipe is full of liquid, the pipe size and liquid parameters are entered correctly, and that the transducers have been mounted accurately. Highly aerated liquids will also cause low signal strength conditions.
SUB FLOW — Substitute Flow (Value)
0.0…100.0
Substitute Flow SUB FLOW is a value that the analog outputs and the flow rate display will indicate when an error condition in the flow meter occurs. The typical setting for this entry is a value that will make the instrument display zero flow during an error condition.
Substitute flow is set as a percentage between MIN RATE and MAX RATE. In a unidirectional system, this value is typically set to zero to indicate zero flow while in an error condition. In a bidirectional system, the percentage can be set such that zero is displayed in a error condition. To calculate where to set the substitute flow value in a bidirectional system, perform the following calculation:

NO
YES Because every flow meter installation is slightly different and sound waves can travel in slightly different ways through these various installations, it is important to remove the zero offset at zero flow to maintain the meter’s accuracy.

DURING ERRORS
1) The pipe must be full of liquid.
2) Flow must be absolute zero - securely close any valves and allow time for any settling to occur.
3) Press ENTER, use the arrow  keys to make the display read YES.
4) Press ENTER.
D-FLT 0 — Set Default Zero Point (Choice)
NO
YES If the flow in a piping system cannot be shut off, allowing the SET ZERO procedure described above to be performed or if an erroneous “zero” flow was captured - like can happen if SET ZERO is conducted with flowing fluid, then the factory default zero should be utilized. To utilize the D-FLT 0 function, simply press ENTER, then press an arrow key to display YES on the display and then press ENTER.
The default zero places an entry of zero (0) into the firmware instead of the actual zero offset entered by using the SET
ZERO procedure.
COR FTR — Correction Factor (Value)
0.500 - 1.500 This function can be used to make the flow meter agree with a different or reference flow meter by applying a correction factor / multiplier to the readings and outputs. A factory calibrated system should be set to 1.000. The range of settings for this entry is 0.500 to 1.500. The following examples describe two uses for the COR FTR entry:
1) The meter is indicating a ow rate that is 4% higher than another ow meter located in the same pipe line. To make the ow meter indicate the same ow rate as the other meter, enter a COR FTR of 0.960 to lower the readings by 4%.
2) An out-of-round pipe, carrying water, causes the ow meter to indicate a measured sound speed that is 7.4% lower than the Table 4.5 value. This pipe condition will cause the ow meter to indi- cate ow rates that are 7.4% lower than actual ow. To correct the ow readings, enter 1.074.

If BATCH was chosen for the totalizer mode, a value for batch accumulation must be entered. This is the value to which the totalizer will accumulate before resetting to zero and repeating the accumulation. This value includes any exponents that were entered in the BSC MENU as TOTAL E.
For example:
1. If BTCH MUL is set to 1000, RATE UNT to LITERS and TOTL E to E0 (liters × 1), then the batch totalizer will accumulate to 1000
liters, return to zero and repeat indenitely. The totalizer will increment 1 count for every liter that has passed.
2. If BTCH MUL is set to 1000, RATE UNT to LITERS and TOTL E to E2 (liters × 100), then the batch totalizer will accumulate to
100,000 liters, return to zero and repeat indenitely. The totalizer will only increment 1 count for every 100 liters that has passed.

SOFT WARE UTILITY
SOFTWARE UTILITY
Introduction
In addition to, or as a replacement for, the keypad entry programming, the flow meter can be used with a software utility. The software utility is used for configuring, calibrating and communicating with this family of flow meters. Additionally, it has numerous troubleshooting tools to make diagnosing and correcting installation problems easier.
This software has been designed to provide the flow meter user with a powerful and convenient way to configure calibrate and troubleshoot all of this families flow meters. A PC can be hard-wired to the flow meter through a standard USB connection found on most current computers.
System Requirements
The software requires a PC-type computer, running Windows 98, Windows ME, Windows 2000, Windows NT, Windows XP, Windows Vista or Windows 7 operating systems and a USB communications port.
Installation
1. From the Windows Start button, choose the Run command. From the Run dialog box, use Browse to navigate to the USP_Setup.exe le and double-click.
2. The USP Setup will automatically extract and install on the hard disk. The USP icon can then be copied to the desktop, if desired.
OTE:N If a previous version of this software is installed, it must be un-installed before a new version of the software can be
installed. Newer versions will ask to remove the old version and perform the task automatically. Older versions must be removed using the Microsoft Windows Add/Remove Programs applet.
OTE:N Most PCs will require a restart after a successful installation.
Initialization
1. Connect the B end of the USB A/B communications cable (P.N. D005-2117-003) to the meters USB communication port and the A end to a convenient USB port on the computer.
OTE:N It is advisable to have the flow meter powered up prior to running this software. OTE:N While the USB cable is connected, the RS485 and frequency outputs are disabled.
2. Double-click on the USP icon. The rst screen is the RUN mode screen, see Figure 39, which contains real-time information regarding ow rate, totals, signal strength, communications status, and the ow meter’s serial number. The COMM indicator in the lower right-hand corner indicates that the serial connection is active. If the COMM box contains a red ERROR indication, select Communications on the Menu bar and select Initialize. Choose the appropriate COM port and the RS232 / USB Com Port Type. Proper communication is veried when a green OK is indicated in the lower right-hand corner of the PC display and the Last Update indicator in the text area on the left side of the screen changes from red to an active clock indication.

The configuration drop-down houses six screens used to control how the flow meter is set up and responds to varying flow conditions. The first screen that appears after clicking the Configuration button is the Basic screen. SeeFigure 40.
BASIC TAB
General
The general heading allows users to select the measurement system for meter setup, either English or metric and choose from a number of pre-programmed small pipe configurations in the Standard Configurations drop-down. If pipe measurements are to be entered in inches, select English. If pipe measurements are to be entered in millimeters, select Metric. If the general entries are altered from those at instrument start-up, then press Download in the lower right-hand portion of the screen and cycle power to the flow meter.
When using the Standard Configurations drop-down menu alternate, menu choices can be made by using the following guidelines:
1. Select the transducer type and pipe size for the transducer to be used. The rmware will automatically enter the appropriate values for that pipe size and type. Every entry parameter except for Units, MODBUS Address, Standard Congurations, Frequency, Flow Direction and Specic Heat Capacity will be unavailable behind a grayed out entry box.
2. Go back to the Standard Congurations drop-down menu and select Custom. As soon as Custom is chosen, the previously grayed out selections will become available for editing.
3. Make any changes to the basic conguration deemed necessary and press Download.
4. To ensure that the conguration changes take eect, turn the power o and then back on again to the transmitter.
Also under the General heading is a field for entering a MODBUS address. If the flow meter is to be used on a multi-drop RS485 network, it must be assigned a unique numerical address. This box allows that unique address to be chosen.
Page 55 March 2014
BASIC TA B
OTE:N This address does not set the Modbus TCP/IP, EtherNet/IP, BACnet address. That is set via the web page interface that
is integrated into the Ethernet port.
OTE:N Do not confuse the MODBUS address with the device address as seen in the upper left-hand corner of the display.
The Device Addr is included for purposes of backward compatibility of first generation flow meter products. The device address has no function and will not change when used with this flow meter family.
Transducer
Transducer Type selects the transducer that will be connected to the flow meter. Select the appropriate transducer type from the drop-down list. This selection influences transducer spacing and flow meter performance, so it must be correct. If you are unsure about the type of transducer to which the flow meter will be connected, consult the shipment packing list or call the manufacturer for assistance.
OTE:N A change of transducer type will cause a system configuration error 1002: Sys Config Changed to occur. This error will
clear when the microprocessor is reset or power is cycled on the flow meter.
Transducer Mount selects the orientation of the transducers on the piping system. See TRANSDUCER INSTALLATION in this manual and Table 2 for detailed information regarding transducer mounting modes for particular pipe and liquid characteristics. Whenever transducer mount is changed, a download command and subsequent microprocessor reset or flow meter power cycle must be conducted.

Transducer Spacing is a value calculated by the flow meter firmware that takes into account pipe, liquid, transducer and
mounting information. This spacing will adapt as these parameters are modified. The spacing is given in inches for English units selection and millimeters for metric. This value is the lineal distance that must be between the transducer alignment marks. Selection of the proper transducer mounting method is not entirely predictable and many times is an iterative process.
OTE:N This setting only applies to DTTN, DTTL, and DTTH transducers.
Transducer Flow Direction allows the change of the direction the meter assumes is forward. When mounting meters with integral transducers, this feature allows upstream and downstream transducers to be electronically reversed, making upside down mounting of the display unnecessary.
Pipe Material is selected from the pull-down list. If the pipe material utilized is not found in the list, select Other and enter the actual pipe material Sound Speed and Roughness (much of this information is available at web sites such as www.ondacorp.
com/tecref_acoustictable.html) for pipe relative roughness calculations.
Pipe O.D. and Wall Thickness are based on the physical dimensions of the pipe on which the transducers will be mounted. Enter this value in inches for English units or millimeters for metric units.
OTE:N Charts listing popular pipe sizes have been included in the APPENDIX of this manual. Correct entries for pipe O.D. and
pipe wall thickness are critical to obtaining accurate flow measurement readings.
Liner Material is selected from the pull-down list. If the pipe liner material utilized is not included in the list, select Other and enter liner material Sound Speed and Roughness (much of this information is available at web sites such as www.ondacorp.
com/tecref_acoustictable.html). See page 41 for pipe liner relative roughness calculations.
Fluid Type is selected from a pull-down list. If the liquid is not found in the list, select Other and enter the liquid Sound Speed and Absolute Viscosity into the appropriate boxes. The liquid’s specific gravity is required if mass measurements are to be made, and the specific heat capacity is required for energy measurements.
Flow Tab
Flow Rate Units are selected from the drop-down lists. Select an appropriate rate unit and time from the two lists. This entry also includes the selection of Flow Rate Interval after the / sign.
Totalizer Units are selected from drop-down lists. Select an appropriate totalizer unit and totalizer exponent. The totalizer exponents are in scientific notation and permit the eight digit totalizer to accumulate very large values before the totalizer “rolls over” and starts again at zero. Table 8 illustrates the scientific notation values and their respective decimal equivalents.

Min Flow is the minimum volumetric flow rate setting entered to establish filtering parameters. Volumetric entries will be in
the flow rate units. For unidirectional measurements, set Min Flow to zero. For bidirectional measurements, set Min Flow to the highest negative (reverse) flow rate expected in the piping system.
Max Flow is the maximum volumetric flow rate setting entered to establish filtering parameters. Volumetric entries will be in the flow rate units. For unidirectional measurements, set Max Flow to the highest (positive) flow rate expected in the piping system. For bidirectional measurements, set Max Flow to the highest (positive) flow rate expected in the piping system.
Low Flow Cutoff is provided to allow very low flow rates (that can be present when pumps are off and valves are closed) to be displayed as zero flow. Typical values that should be entered are between 1.0…5.0% of the flow range between
Min Flow and Max Flow.
Low Signal Cutoff is used to drive the flow meter and its outputs to the value specified in the Substitute Flow field when
conditions occur that cause low signal strength. A signal strength indication below 5 is generally inadequate for measuring flow reliably, so generally the minimum setting for low signal cutoff is 5. A good practice is to set the low signal cutoff at approximately 60…70% of actual measured maximum signal strength.
OTE:N The factory default low signal cutoffis five.
If the measured signal strength is lower than the low signal cutoff setting, a Signal Strength too Low highlighted in red will become visible in the text area to the left in the Data Display screen until the measured signal strength becomes greater than the cutoff value.
Signal strength indication below two is considered to be no signal at all. Verify that the pipe is full of liquid, the pipe size and liquid parameters are entered correctly, and that the transducers have been mounted accurately. Highly aerated liquids will also cause low signal strength conditions.
Substitute Flow is a value that the analog outputs and the flow rate display will indicate when an error condition in the flow meter occurs. The typical setting for this entry is a value that will make the instrument display zero flow during an error condition.
Substitute flow is set as a percentage between Min Flow and Max Flow. In a unidirectional system, this value is typically set to zero to indicate zero flow while in an error condition. In a bidirectional system, the percentage can be set such that zero is displayed in an error condition. To calculate where to set the Substitute Flow value in a bidirectional system, perform the following operation:

Entry of data in the Basic and Flow tabs is all that is required to provide flow measurement functions to the flow meter. If the user is not going to utilize input/output functions, press Download to transfer the configuration to the flow meter instrument. When the configuration has been completely downloaded, turn the power to the meter off and then on again to guarantee the changes take effect.

Filtering Tab
The Filtering tab contains several filter settings for the flow meter. These filters can be adjusted to match response times and data “smoothing” performance to a particular application.

Time Domain Filter (range 1…256) adjusts the number of raw data sets (the wave forms viewed on the software Diagnostics Screen) that are averaged together. Increasing this value will provide greater damping of the data and slow the response time
of the flow meter. Conversely, lowering this value will decrease the response time of the meter to changes in flow/energy rate. This filter is not adaptive, it is operational to the value set at all times.
OTE:N The flow meter completes a measurement in approximately 350…400 mS. The exact time is pipe size dependent.
Flow Filter (Damping) establishes a maximum adaptive filter value. Under stable flow conditions (flow that varies less than the Flow Filter Hysteresis entry), this adaptive filter will increase the number of successive flow readings that are averaged together
up to this maximum value. If flow changes outside of the flow filter hysteresis window, the filter adapts by decreasing the number of averaged readings and allows the meter to react faster.
The damping value is increased to increase stability of the flow rate readings. Damping values are decreased to allow the flow meter to react faster to changing flow rates. The factory settings are suitable for most installations. Increasing this value tends to provide smoother steady-state flow readings and outputs.
Flow Filter Hysteresis creates a window around the average flow measurement reading allowing small variations in flow without changing the damping value. If the flow varies within that hysteresis window, greater display damping will occur up to the maximum values set by the flow filter entry. The filter also establishes a flow rate window where measurements outside of the window are examined by the Bad Data Rejection filter. The value is entered as a percentage of actual flow rate.
For example, if the average flow rate is 100 gpm and the Flow Filter Hysteresis is set to 5%, a filter window of 95…105 gpm is established. Successive flow measurements that are measured within that window are recorded and averaged in accordance with the Flow Filter Damping setting. Flow readings outside of the window are held up in accordance with the Bad Data
Rejection filter.
Flow Filter MinHysteresis sets a minimum hysteresis window that is invoked at sub 0.25 fps (0.08 mps) flow rates, where the “of
rate” flow filter hysteresis is very small and ineffective. This value is entered in pico-seconds (ρsec) and is differential time. If very small fluid velocities are to be measured, increasing the flow filter minhysteresis value can increase reading stability.
Page 59 March 2014
BASIC TA B
Flow Filter Sensitivity allows configuration of how fast the Flow Filter Damping will adapt in the positive direction.
Increasing this value allows greater damping to occur faster than lower values. Adaptation in the negative direction is not user adjustable.
Bad Data Rejection is a value related to the number of successive readings that must be measured outside of the Flow Filter Hysteresis or Flow Filter MinHysteresis windows before the flow meter will use that flow value. Larger values are entered into Bad Data Rejection when measuring liquids that contain gas bubbles, as the gas bubbles tend to disturb the ultrasonic signals
and cause more extraneous flow readings to occur. Larger Bad Data Rejection values tend to make the flow meter more sluggish to rapid changes in actual flow rate.
Output Tab
The entries made in the Output tab establish input and output parameters for the flow meter. Select the appropriate function from the pull-down menu and press Download. When a function is changed from the factory setting, a configuration error 1002 will result. This error will be cleared by resetting the flow meter microprocessor from the Communications/Commands/ Reset Target button or by cycling power on the flow meter. Once the proper output is selected and the microprocessor is reset, calibration and configuration of the modules can be completed.

Channel 1 – 4-20 mA Conguration
OTE:N The 4-20 mA Output menu applies to all flow meter versions and is the only output choice for Channel 1.
The channel 1 menu controls how the 4-20 mA output is spanned for all models and how the frequency output is spanned for the flow only model.
The Flow at 4 mA / 0 Hz and Flow at 20 mA / 1000 Hz settings are used to set the span for both the 4-20 mA output and the 0…1000 Hz frequency output on the flow only versions.
The 4-20 mA output is internally powered (current sourcing) and can span negative to positive flow/energy rates. This output interfaces with virtually all recording and logging systems by transmitting an analog current that is proportional to system flow rate. Independent 4 mA and 20 mA span settings are established in firmware using the flow measuring range entries. These entries can be set anywhere in the –40…40 fps (–12 …12 mps) range of the instrument. Resolution of the output is 12-bits (4096 discrete points) and can drive up to a 400 Ohm load when the meter is AC powered. When powered by a DC supply, the load is limited by the input voltage supplied to the instrument. See Figure 23 for allowable loop loads.
Page 60 March 2014
BASIC TA B
Flow at 4 mA / 0 Hz
Flow at 20 mA / 1000 Hz
The Flow at 4 mA / 0 Hz and Flow at 20 mA / 1000 Hz entries are used to set the span of the 4-20 mA analog output and the frequency output on flow only versions. These entries are volumetric rate units that are equal to the volumetric units configured as rate units and rate interval discussed on page 44.
For example, to span the 4-20 mA output from –100…100 gpm with 12 mA being 0 gpm, set the Flow at 4 mA / 0 Hz and Flow at 20 mA / 1000 Hz inputs as follows:
Flow at 4 mA / 0 Hz = –100.0
Flow at 20 mA / 1000 Hz = 100.0
If the meter is a flow only model, this setting would also set the span for the frequency output. At –100 gpm, the output frequency would be 0 Hz. At the maximum flow of 100 gpm, the output frequency would be 1000 Hz, and in this instance a flow of zero would be represented by an output frequency of 500 Hz.
Example 2 – To span the 4-20 mA output from 0 …100 gpm with 12 mA being 50 gpm, set the Flow at 4 mA / 0 Hz and Flow at 20 mA / 1000 Hz inputs as follows:
Flow at 4 mA / 0 Hz = 0.0
Flow at 20 mA / 1000 Hz = 100.0
For the meter, in this instance, zero flow would be represented by 0 Hz and 4 mA. The full scale flow or 100 gpm would be 1000 Hz and 20 mA and a midrange flow of 50 gpm would be expressed as 500 Hz and 12 mA.
The 4-20 mA output is factory calibrated and should not require adjustment. If small adjustments to the DAC (Digital to Analog Converter) are needed, for instance if adjustments due to the accumulation of line losses from long output cable lengths are required, the Calibration 4 mA and Calibration 20 mA can be used.
Calibration 4 mA — 4 mA DAC Calibration Entry (Value)
Calibration 20 mA— 20 mA DAC Calibration Entry (Value)
The Calibration 4 mA and Calibration 20 mA entries allows fine adjustments to be made to the “zero” and full scale of the 4-20 mA output. To adjust the outputs, an ammeter or reliable reference connection to the 4-20 mA output must be present.
OTE:N Calibration of the 20 mA setting is conducted much the same way as the 4 mA adjustments. OTE:N The Calibration 4 mA and Calibration 20 mA entries should not be used in an attempt to set the 4-20 mA range.
Utilize Flow at 4 mA / 0 Hz and Flow at 20 mA / 1000 Hz detailed above for this purpose.
4 mA Calibration Procedure:
1. Disconnect one side of the current loop and connect the ammeter in series (disconnect either wire at the terminals labeled 4-20 mA Out or Signal Gnd).
2. Using the arrow keys, increase the numerical value to increase the current in the loop to 4 mA. Decrease the value to decrease the current in the loop to 4 mA. Typical values range between 40…80 counts.
3. Reconnect the 4-20 mA output circuitry as required.
20 mA Calibration Procedure:
1. Disconnect one side of the current loop and connect the ammeter in series (disconnect either wire at the terminals labeled 4-20 mA Out or Signal Gnd).
2. Using the arrow keys, increase the numerical value to increase the current in the loop to 20 mA. Decrease the value to decrease the current in the loop to 20 mA. Typical values range between 3700…3900 counts.
3. Reconnect the 4-20 mA output circuitry as required.
4-20 Test — 4-20 mA Output Test (Value)
Allows a simulated flow value to be sent from the 4-20 mA output. By incrementing this value, the 4-20 mA output will transmit the indicated current value.

Channel 2 - RTD Conguration [for energy units Only]
OTE:N The Channel 2 Menu is used to configure model specific I/O options. The flow only meter presents a different set of
parameters than the energy meter.
IT IS POSSIBLE TO CHOOSE OPTIONS PERTAINING ONLY TO THE FLOW ONLY MODEL WHEN AN ENERGY METER IS PRESENT. THE OPPOSITE IS ALSO TRUE. THE PROPER MENU TYPE MUST BE CHOSEN FOR THE ACTUAL METER. IF THIS CAUTION ISN’T FOLLOWED, THE OUTPUTS OR METER READINGS WILL BE UNPREDICTABLE.
Inputs from two 1000 Ohm platinum RTD temperature sensors allow the measurement of energy delivered in liquid heating and cooling systems.
The values used to calibrate the RTD temperature sensors are derived in the laboratory and are specific to a specific RTD. The RTDs on new units come with the calibration values already entered into the energy meter and should not need to be changed.
Field replacement of RTDs is possible thru the use of the keypad or the software. If the RTDs were ordered from the manufacturer, they will come with calibration values that need to be loaded into the energy meter.
RTD Calibration Procedure:
1. Enter the calibration values for RTD #1 A and RTD #1 B followed by RTD #2 A and RTD #2 B.
2. Double-click Download to send the values to memory.
3. Turn the power o and then back on to the ow meter to enable the changes to take eect.

The first screen, Page 1 of 3 establishes a baseline zero flow rate measurement for the instrument.
Because every flow meter installation is slightly different and sound waves can travel in slightly different ways through these various installations, it is important to remove the zero offset at zero flow to maintain the meters accuracy. A provision is made using this entry to establish zero flow and eliminate the offset.
To zero the flow meter:
1. Establish zero ow in the pipe (ensure that the pipe is full of uid, turn o all pumps, and close a dead-heading valve). Wait until the delta time interval shown in Current Delta T is stable (and typically very close to zero).
2. Press Set.
3. Press Next when prompted, then press Finish on the calibration screen.
The zeroing process is essential in systems using the DTTS and DTTC transducer sets to ensure the best accuracy.

Repeat for as many points as desired.
OTE:N If only two points are to be used (zero and span), it is preferable to use the highest flow rate anticipated in normal
operation as the calibration point. If an erroneous data point is collected, the point can be removed by pressing Edit, selecting the bad point and then selecting Remove.

1. Calc Count – The number of ow calculations performed by the meter beginning at the time the power to the meter was last turned o and then on again.
2. Sample Count – The number of samples currently being taken in one second.
3. Raw Delta T (ηs) – The actual amount of time it takes for an ultrasonic pulse to cross the pipe.
4. 4) Course Delta T – This meter series uses two wave forms. The coarse to nd the best delay and other timing measurements and a ne to do the ow measurement.
5. Gain – The amount of signal amplication applied to the reected ultrasound pulse to make it readable by the digital signal processor.
6. Gain Setting/Waveform Power – The rst number is the gain setting on the digital pot (automatically controlled by the AGC circuit). Valid numbers are from 1…100. The second number is the power factor of the current waveform being used. For example, 8 indicates that a 1/8 power wave form is being used.
7. Tx Delay – The amount of time the transmitting transducer waits for the receiving transducer to recognize an ultrasound signal before the transmitter initiates another measurement cycle.
8. Flow Filter – The current value of the adaptive lter.
9. SS (Min/Max) – The minimum and maximum signal strength levels encountered by the meter beginning at the time the power to the meter was last turned o and then on again.
10. 1Signal Strength State – Indicates if the present signal strength minimum and maximum are within a pre– programed signal strength window.
11. Sound Speed – The actual sound speed being measured by the transducers at that moment.
12. Reynolds – A number indicating how turbulent a uid is. Reynolds numbers between 0 and 2000 are considered laminar ow. Numbers between 2000…4000 are in transition between laminar and turbulent ows and numbers greater than 4000 indicate turbulent ow.
13. Reynolds Factor – The value applied to the ow calculation to correct for variations in Reynolds numbers.

Table 13: Available data formats
Modbus Register / Word Ordering
Each Modbus Holding Register represents a 16-bit integer value (2 bytes). The official Modbus standard defines Modbus as a ‘big-endian’ protocol where the most significant byte of a 16-bit value is sent before the least significant byte. For example, the 16-bit hex value of ‘1234’ is transferred as ‘12’ ‘34’.
Beyond 16-bit values, the protocol itself does not specify how 32-bit (or larger) numbers that span over multiple registers should be handled. It is very common to transfer 32-bit values as pairs of two consecutive 16-bit registers in little-endian word order. For example, the 32-bit hex value of ‘12345678’ is transferred as ‘56’ ‘78’ ‘12’ ‘34’. Notice the Register Bytes are still sent in big-endian order per the Modbus protocol, but the Registers are sent in little-endian order.
Other manufacturers, store and transfer the Modbus Registers in big-endian word order. For example, the 32-bit hex value of ‘12345678’ is transferred as ‘12’ ‘34’ ‘56’ ‘78’. It doesn’t matter which order the words are sent, as long as the receiving device knows which way to expect it. Since it’s a common problem between devices regarding word order, many Modbus master devices have a configuration setting for interpreting data (over multiple registers) as ‘little-endian’ or ‘big-endian’ word order. This is also referred to as swapped or word swapped values and allows the master device to work with slave devices from different manufacturers.
If, however, the endianness is not a configurable option within the Modbus master device, it’s important to make sure it matches the slave endianess for proper data interpretation. The flow meter actually provides two Modbus Register maps to accommodate both formats. This is useful in applications where the Modbus Master cannot be configured for endianness.

HEATING AND COOLING MEASUREMENT
HEATING AND COOLING MEASUREMENT
The energy meter is designed to measure the rate and quantity of heat delivered to a given building, area or heat exchanger. The instrument measures the volumetric flow rate of the heat exchanger liquid (water, water/glycol mixture, brine, etc.), the temperature at the inlet pipe and the temperature at the outlet pipe. Heat delivery is calculated by the following equation:
RATE OF HEAT DELIVERY

Where:
Q = Quantity of heat absorbed V = Voluem of liquid passed
K = Heat coefficient of the liquid
θ = Temperature difference between supply
and return

Type 1000 Ohm
Accuracy ±0.3 °C (0.0385 curve)
Temperature Response Positive Temperature Coefficient
Platinum RTD
The RTD temperature measurement circuit in the energy meter measures the differential temperature of two 1000 Ohm, three-wire platinum RTDs. The three-wire configuration allows the temperature sensors to be located several hundred feet away from the meter without influencing system accuracy or stability.
The energy meter allows integration of two 1000 Ohm platinum RTDs with the energy flow meter, effectively providing an instrument for measuring energy delivered in liquid cooling and heating systems. If RTDs were ordered with the energy flow meter, they have been factory calibrated and are shipped connected to the module as they were calibrated.
Field replacement of RTDs is possible thru the use of the keypad or the software utility. If the RTDs were ordered from the manufacturer of the energy meter, they will come with calibration values that need to be loaded into the energy meter.
New, non-calibrated RTDs will need to be field calibrated using an ice bath and boiling water to derive calibration values. This procedure is outlined below.

OTE:N An ice bath and boiling water bath are used in these examples because their temperatures are easy to maintain
and provide known temperature reference points. Other temperature references can be used as long as there is a minimum delta T of 40° C between the two references.
OTE:N For maximum RTD temperature below 100° C, the hot water bath should be heated to the maximum temperature for
that RTD.
6. Press Calibrate and the following screen should now be visible. Make sure that the Calibrate Both RTDs at same temperature box is checked and then enter the temperature to the nearest 0.1° C in the box labeled Reference Temp (deg C).
7. Press Next.
The procedure for step 2 of 2 is similar to step 1 except the second water bath is used.

K FACTORS EXPLAINED
The K factor (with regards to flow) is the number of pulses that must be accumulated to equal a particular volume of fluid. You can think of each pulse as representing a small fraction of the totalizing unit.
An example might be a K factor of 1000 (pulses per gallon). This means that if you were counting pulses, when the count total reached 1000, you would have accumulated one gallon of liquid. Using the same reasoning, each individual pulse represents an accumulation of 1/1000 of a gallon. This relationship is independent of the time it takes to accumulate the counts.
The frequency aspect of K factors is a little more confusing because it also involves the flow rate. The same K factor number, with a time frame added, can be converted into a flow rate. If you accumulated 1000 counts (one gallon) in one minute, then your flow rate would be one gpm. The output frequency, in Hz, is found simply by dividing the number of counts (1000) by the number of seconds in a minute (60) to get the output frequency.
1000 ÷ 60 = 16.6666 Hz. If you were looking at the pulse output on a frequency counter, an output frequency of 16.666 Hz would be equal to one gpm. If the frequency counter registered 33.333 Hz (2 × 16.666 Hz), then the flow rate would be two gpm.
Page 96 March 2014
K FAC TORS EXPLAINED
Finally, if the flow rate is two gpm, then the accumulation of 1000 counts would take place in 30 seconds because the flow rate, and hence the speed that the 1000 counts is accumulated, is twice as great.
Calculating K factors
Many styles of flow meters are capable of measuring flow in a wide range of pipe sizes. Because the pipe size and volumetric units the meter will be used on vary, it may not possible to provide a discrete K factor. In the event that a discrete K factor is not supplied then the velocity range of the meter is usually provided along with a maximum frequency output.
The most basic K factor calculation requires that an accurate flow rate and the output frequency associated with that flow rate be known.
Example 1
Known values are:
Frequency = 700 Hz
Flow Rate = 48 gpm
700 Hz × 60 sec = 42,000 pulses per min
K factor
Example 2
Known values are:
Full Scale Flow Rate = 85 gpm
Full Scale Output Frequency = 650 Hz
650 Hz × 60 sec = 39,000 pulses per min
K factor
The calculation is a little more complex if velocity is used because you first must convert the velocity into a volumetric flow rate to be able to compute a K factor.
To convert a velocity into a volumetric flow, the velocity measurement and an accurate measurement of the inside diameter of the pipe must be known. Also needed is the fact that one US gallon of liquid is equal to 231 cubic inches.
Example 3
Known values are:
Velocity = 4.3 ft/sec
Inside Diameter of Pipe = 3.068 in.

So for every foot of fluid travel 0.384 gallons will pass.
What is the flow rate in gpm at 4.3 ft/sec?
0.384 gallons × 4.3 FPS × 60 sec (1 min) = 99.1 gpm
Now that the volumetric flow rate is known, all that is needed is an output frequency to determine the K factor.
Known values are:
Frequency = 700 Hz (By measurement)
Flow Rate = 99.1 gpm (By calculation)
700 Hz × 60 sec = 42,000 pulses per gallon
