Quick-Start Operating Overview

QUICKSTART OPERATING OVERVIEW

If you are familiar with installing TFX Ultra meters, follow these instructions to get the system up and running quickly. Refer to the detailed instructions if you require additional information.

OTE:N The following steps require information supplied by the transmitter itself so it will be necessary to supply power to

the transmitter, at least temporarily, to obtain setup information.

Transducer Location

• 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 five straight diameters downstream. See Table 2 on page16 for additional configurations.

• 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 3 on page17. The three transducer mounting configurations are shown in

Figure 1. See “Transducer Mounting Configurations” on page20 for mounting procedures.

• Avoid installations on downward flowing pipes or pipes that may become partially filled.

OTE:N All DTTS and DTTC transducers use V–Mount configuration.

1. Place the transmitter in signal strength measuring mode. This value is available on the transmitters display Service Menu or in the data display of the UltraLink software utility.

2. The pipe surface, where the transducers are to be mounted, must be clean and dry. Remove scale, rust or loose paint to ensure satisfactory acoustic conduction. Wire brushing the rough surfaces of pipes to smooth bare metal may also be useful. Plastic pipes do not require preparation other than cleaning.

3. Apply a single 1/2 inch (12 mm) bead of acoustic couplant grease to the upstream transducer and secure it to the pipe with a mounting strap.

4. Apply acoustic couplant grease to the downstream transducer and press it onto the pipe using hand pressure at the lineal distance calculated in “Transducer Location” on page8.

5. Space the transducers according to the recommended values found during programming or from the UltraLink software utility. Secure the transducers with the mounting straps at these locations.

DTTS and DTTC Transducers

1. Place the transmitter in signal strength measuring mode. This value is available on the transmitter’s display Service Menu or in the data display of the UltraLink software utility.

3. Apply a single 1/2 inch (12 mm) bead of acoustic couplant grease to the top half of the transducer and secure it to the pipe with the bottom half or with U-bolts.

4. Tighten the nuts so the acoustic coupling grease begins to ow out from the edges of the transducer and from the gap between the transducer and the pipe.

MPORTANTI

Do not overtighten. Overtightening will not improve performance and may damage the transducer.

Initial Settings and Powerup

1. Apply power to the transmitter.

2. Verify that SIG STR is greater than 5.0.

3. Input the units of measure and the I/O data.

Introduction

INTRODUCTION

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

This family of transit time transmitters uses 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.

Application Versatility

The TFX Ultra transmitter 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 transmitter is not affected by system pressure, fouling or wear.

CE Compliance

The transmitter can be installed in conformance to CISPR 11 (EN 55011) standards. See “CE Compliance Drawings” on

page104.

User Safety

The TFX Ultra transmitter employs modular construction and provides electrical safety for the operator. The display face contains voltages no greater than 28V DC. The display face swings open to allow access to user connections.

DANGER

THE POWER SUPPLY BOARD CAN HAVE LINE VOLTAGES APPLIED TO IT, SO DISCONNECT ELECTRICAL POWER BEFORE OPENING THE INSTRUMENT ENCLOSURE. WIRING SHOULD ALWAYS CONFORM TO LOCAL CODES AND THE NATIONAL ELECTRICAL CODE.

Data Integrity

Non-volatile flash memory retains all user-entered configuration values in memory for several years at 77° F (25° C), even if power is lost or turned off. Password protection is provided as part of the Security menu (SEC MENU) and prevents inadvertent configuration changes or totalizer resets.

Product Identication

The serial number and complete model number of the transmitter are located on the top outside surface of the transmitter body. Should technical assistance be required, please provide our customer service department with this information. See

“Product Labels” on page96.

The 24V AC power supply option for this transmitter is intended for a typical HVAC and Building Control Systems (BCS) powered by a 24V AC, nominal, power source. This power source is provided by AC line power to 24V AC drop-down transformer and is installed by the installation electricians.

OTE:N In electrically noisy applications, grounding the

transmitter to the pipe where the transducers are mounted may provide additional noise suppression. This approach is only effective with conductive metal pipes. The earth (chassis) ground derived from the line voltage power supply should be removed at the transmitter and a new earth ground connected between the transmitter and the pipe being measured.

OTE:N Wire gauges up to 14 AWG can be accommodated in the transmitter terminal blocks.

OTE:N AC-powered transmitters are protected by a field-replaceable fuse. The fuse is a time delay fuse rated at 0.5A/250V

Transducer Installation

TRANSDUCER INSTALLATION

The transducers for the TFX Ultra transmitter contain piezoelectric crystals that transmit and receive ultrasonic signals through the walls of liquid piping systems.

DTTR, DTTN, 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. CAREFULLY EXECUTE THESE INSTRUCTIONS.

DTTS and DTTC small pipe transducers have integrated transmitter and receiver elements that eliminate the requirement for spacing measurement and alignment.

Mounting the DTTR, DTTN, DTTL and DTTH clamp-on ultrasonic transit time transducers takes five steps:

1. Select the optimum location on a piping system.

2. Select a mounting conguration.

3. Enter the pipe and liquid parameters into the UltraLink software utility or key them into the transmitter. The UltraLink software utility or the transmitter’s rmware calculates proper transducer spacing based on these entries.

4. Prepare the pipe and mount the transducers.

5. Wire the transducers to the transmitter.

Downstream+ DownstreamUpstreamUpstream+

Figure 7: Transducer connections

The Energy model transmitter requires two 1000 Ohm, three-wire, platinum RTDs. The RTDs are available in surface-mount and insertion (wetted) styles. Use surface-mount RTDs on well insulated pipes. Use insertion RTDs on non-insulated pipes.

Select a 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) displaying on the transmitter while the pipe is empty. This error code will clear automatically once the pipe refills with liquid. Do not mount the transducers in an area where the pipe may become partially filled, such as the highest point in a flow loop. Partially filled pipes will cause erroneous and unpredictable operation of the transmitter.

• A piping system that contains lengths of straight pipe such as those described in Table 2. The optimum straight pipe diameter recommendations apply to pipes in both horizontal and vertical orientation. The straight runs in Table 2 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.

• An area where the transducers will not be inadvertently bumped or disturbed during normal operation.

• NOT on downward flowing pipes unless adequate downstream head pressure is present to overcome partial filling of or cavitation in the pipe.

Transducer Installation

Select a Mounting Conguration

The transmitter can be used with six different transducer types: DTTR, DTTN, DTTL, DTTH DTTS and DTTC. Meters that use the DTTR, DTTN, DTTL or DTTH, transducer sets consist of two separate sensors that function as both ultrasonic transmitters and receivers. These transducers are clamped on the outside of a closed pipe at a specific distance from each other. DTTS and DTTC transducers integrate both the transmitter and receiver into one assembly that fixes the separation of the piezoelectric crystals.

The DTTR, 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.

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 transmitter 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.

The appropriate mounting configuration is based on pipe and liquid characteristics. Selecting the proper transducer mounting method is an iterative process. Table 3 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.

For pipes 24 inches (600 mm) and larger, use the DTTL transducers with a transmission frequency of 500 kHz.

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 partially buried where a V-mount is required or desired.

For DTTS and DTTC transducers, the transducers are V-mount. The frequency setting depends on the pipe material.

Transducer Installation

Enter the Pipe and Liquid Parameters

The TFX Ultra metering system calculates proper transducer spacing based on the piping and liquid information you enter into the transmitter via the integral keypad or the UltraLink software utility.

The most accuracy is achieved when the transducer spacing is exactly what the transmitter calculates, so use the calculated spacing if the 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. In that case, place the transducers at the highest signal level observed when moving the transducers slowly around the mount area.

OTE:N Transducer spacing is calculated on “ideal” pipe. Ideal pipe almost never exists, so you may need to alter the

transducer spacing. 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 transmitter before mounting the transducers.

The following information is required before programming the instrument:

Transducer mounting configuration Pipe liner thickness (if present) Pipe O.D. (outside diameter) Pipe liner material (if present) Pipe wall thickness Fluid type Pipe material Fluid sound speed Pipe sound speed

Nominal values for these parameters are included within the transmitter’s operating system. The nominal values may be used as they appear or may be modied if exact system

values are known.

Fluid viscosity

Table 5: Parameters required

Pipe relative roughness

Fluid specific gravity

OTE:N Much of the data relating to material sound speed, viscosity and specific gravity is pre-programmed into the

transmitter. You need to modify this data only if you know that a particular application’s data varies from the reference values. See “Configuration” on page35 for instructions on entering configuration data into the transmitter via the transmitter’s keypad. See “Parameter Configuration Using UltraLink Software” on page48 for data entry via the software.

After entering the data listed above, the transmitter will calculate proper transducer spacing for the particular data set. The distance will be in inches if the transmitter is configured in English units, or millimeters if configured in metric units.

Mount the Transducer

After selecting an optimal mounting location and determining the proper transducer spacing, mount the transducers onto the pipe.

1. Clean the surface of the pipe. If the pipe has external corrosion or dirt, wire brush, sand or grind the mounting location until it is smooth and clean. 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.

2. Orient and space the DTTR, DTTN, DTTL and DTTH transducers on the pipe to provide optimum reliability and performance. On horizontal pipes, when Z-Mount is required, mount the transducers 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 9. Also see “Z-Mount

Configuration” on page22. 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 DTTR, DTTN and DTTH transducers, and 1.2 inches (30 mm) back from the nose of the DTTL transducers. See Figure 10.

Mount DTTS and DTTC transducers with the cable exiting within ±45 degrees of the side of a horizontal pipe. On vertical pipes, the orientation does not apply.

Apply the Couplant

For DTTR, 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 11. Couplant is provided with the transducers. 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 operating temperature of the pipe is acceptable. For pipe surface temperature over 130° F (55° C), use high temperature acoustic coupant such as Krytox® LVP (P.N. D002-2011-012). For installations that must be silicone free, use Molykote G-N couplant (P.N. D002-2011-009).

(12 mm)

Figure 11: Application of couplant

Position and Secure the Transducer

1. Place the upstream transducer in position on the pipe. Slide the strap into the arched groove on the end of the transducer. Wrap the strap around the pipe. Slide the free end of the strap into the end clip of the strap with the screw at 90 degrees to the strap. Pull the strap through until it loosely ts around the pipe. Rotate the screw so it is parallel to the strap and tighten the screw slightly to help hold the transducer onto the pipe. Verify that the transducer is true to the pipe and adjust as necessary. Tighten the strap screw to secure the transducer to the pipe.

2. Place the downstream transducer on the pipe at the calculated transducer spacing. See Figure 12 on page21. Apply rm hand pressure. If signal strength is greater than ve, secure the transducer at this location. If the signal strength is not ve 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 transmitter’s display or on the main data screen in the UltraLink software utility. See “Parameter Configuration Using UltraLink Software” on page48. 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 applicationspeci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 second. Move the transducer 1/8 inch then wait to see if the signal is

increasing or decreasing. Repeat until the highest level is achieved.

3. If, after adjusting the transducers, the signal strength does not rise to above ve, use an alternate transducer mounting conguration. If the mounting conguration was W-Mount, re-congure the transmitter for V-Mount, move the downstream transducer to the new spacing distance and repeat the procedure “Mount the Transducer” on page19.

Page 20 March 2018TTM-UM-00136-EN-08

Transducer Installation

OTE:N Mounting the high temperature transducers is similar

to mounting the DTTR/DTTN/DTTL transducers. High temperature installations require acoustic couplant that is rated not to flow at the operating temperature of the pipe surface.

OTE:N Use the DTTL on pipes 24 inches and larger and not

on pipes smaller than 4 inches. You can consider using 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. Instead, contact the manufacturer to arrange for a replacement transducer that is the correct size.

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 13.

2. On horizontal pipes, mount the transducer in an orientation so 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.

3. Tighten the wing nuts or U-bolts so the acoustic coupling grease begins to ow out from the edges of the transducer or from the gap between the transducer halves.

MPORTANTI

Do not overtighten. Overtightening will not improve performance and may damage the transducer.

4. If signal strength is less than ve, remount the transducer at another location on the piping system.

Z-Mount Configuration

Installation on larger pipes requires careful measurements of the linear and radial placement of the DTTR, 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 18. 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 19.

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 9 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 “Select a Mounting Configuration” on page17. Mark this location on the pipe.

Page 22 March 2018TTM-UM-00136-EN-08

Transducer 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 equation for the length of 1/2 the circumference is: 1/2 Circumference = Pipe O.D. × 1.57

The transducer spacing is the same as found in “Position and Secure the Transducer” on page20. Mark opposite corners of the paper on the pipe. Apply transducers to these two marks.

5. For DTTR, 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 11. 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 operating temperature of the pipe is 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.

Figure 20: Z-Mount transducer placement

7. Place the downstream transducer on the pipe at the calculated transducer spacing. See Figure 20. 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. A signal strength between 5…98 is acceptable.

The factory default signal strength setting is five. However there are many application-specific conditions that may prevent the signal strength from attaining this level. A minimum signal strength of five is acceptable as long as this signal level is maintained under all flow 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 transmitter with very high signal strength is that the signals may saturate the input amplifiers 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 off-line with the other transducer to lower signal strength.

8. Secure the transducer with a stainless steel strap or other fastener.

Transducer Installation

Mounting Rail System Installation for DTTR

For remote flow DTTR transducers with outside diameters between 2…10 inches (50…250 mm) , the rail mounting kit aids in installation and positioning of the transducers. Transducers slide on the rails, which have measurement markings that are viewable through the sight opening.

1. 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. On vertical pipe, orientation is not critical. Check that the track is parallel to the pipe and that all four mounting feet are touching the pipe.

2. Slide the two transducer clamp brackets toward the center mark on the mounting rail.

3. Place a single bead of couplant, approximately 1/2 inch (12 mm) thick, on the at face of the transducer. See Figure 11 on page20.

4. 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 and transducer so the notch in the clamp aligns with the zero on the scale. See Figure 22.

5. Secure with the thumb screw. Check 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.)

6. 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.

Figure 21: Mounting rail system for DTTR

Mounting Track Installation for DTTN/DTTH

A convenient transducer mounting track can be used for pipes that have outside diameters between 2…10 inches (50…250 mm) and for DTTN/DTTH transducers. If the pipe is outside of that range, mount the transducers separately.

2. Slide the two transducer clamp brackets toward the center mark on the mounting rail.

3. Place a single bead of couplant, approximately 1/2 inch (12 mm) thick, on the at face of the transducer. See Figure 11 on page20.

Loop Load (Ohms)

Inputs/Outputs

INPUTS/OUTPUTS

General

The transmitting system is available in two configurations:

• The Flow-Only model 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 (BTU) model has inputs for two 1000 Ohm RTD sensors in place of the rate frequency and alarm outputs. This model 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 transmitters, the 4-20 mA output is driven from a 15V DC source located within the transmitter. The source is isolated from earth ground connections within the transmitter. The AC-powered transmitter can accommodate loop loads up to 400 Ohms. DC-powered transmitters use 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.

Rate Alarm Outputs

The flow rate output permits output changeover at two separate flow rates, allowing operation with an adjustable switch deadband. Figure 28 illustrates how the setting of the two setpoints 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.

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.

Batch/Totalizer Output (Flow-Only Model)

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.

Error Alarm Outputs

When a control output is set to ERROR mode, the output will activate when any error occurs in the transmitter that has caused the transmitter to stop measuring reliably. See “Brad Harrison® Connector Option” on page95.

Page 27 March 2018 TTM-UM-00136-EN-08

Inputs/Outputs

Frequency Output (Flow-Only Model)

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 “Startup” on page35.

Figure 29: Frequency output switch settings

OTE:N When a USB programming cable is connected, the RS485 and frequency outputs are disabled.

The frequency output is proportional to the maximum flow rate entered into the transmitter. The maximum output frequency is 1000 Hz.

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 transmitter, 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.

Full Scale Units

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:

Pulses Per Gallon

If the frequency output is to be used as a totalizing output, the transmitter 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 transmitters such as turbines, gear or nutating disc meters, the Kfactor can be changed by modifying the MAX RATE flow rate value. See “Calculating KFactors” on page106.

Page 28 March 2018TTM-UM-00136-EN-08

Inputs/Outputs

There are two frequency output options available:

• The Turbine Meter Simulation option is used when a receiving instrument is capable of interfacing directly with a turbine transmitter’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.

500 mV

Figure 30: Frequency output waveform (simulated turbine)

• The Square-Wave Frequency option is used 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 used by leaving SW3 OFF. Set SW4 to ON for a square-wave output.

Wiring and configuration of the Energy model is similar to the totalizing pulse output for the Flow-Only model. This option must use an external current limiting resistor.

RS485 Port

The RS485 feature allows up to 126 transmitters to be placed on a single three-wire cable bus. All transmitters are assigned a unique numeric address that allows all of the transmitters on the cable network to be independently accessed. A Modbus RTU command protocol is used to interrogate the transmitters. See “Communications Protocols” on page66.

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 transmitters, use three-wire shielded cable (like the Belden 9939 or equal). In noisy environments, connect the shield on one end to a good earth-ground connection. Use a USB-to-RS485 converter (like the B&B Electronics P/N 485USBTB-2W) to communicate with a PC running Windows XP, Windows Vista and Windows 7. For computers with RS232C serial ports, use an RS232C-to-RS485 converter (like the B&B Electronics P/N 485SD9TB illustrated in Figure 33), to interconnect the RS485 network to a communication port on a PC. If more than 126 transmitters must be monitored, an additional converter and communication port are required.

Heat Flow for Energy Model Only

Ethernet Port

The Ethernet port is 10/100 Base T with an RJ connector and supports BACnet IP, Modbus TCP/IP and EtherNet/IP protocols. The Ethernet option must be ordered with the transmitter. For Energy models, the Ethernet option is not available with the Totalizing Pulse option.

See”Communications Protocols” on page66 for information on configuring Ethernet settings.

USB Programming Port

The USB programming port is a USB 2.0 Type B connector similar to the USB port on many printers. The USB programming port on the transmitter is the cable connection point from a computer with UltraLink software. UltraLink is used for configuring, calibrating and troubleshooting the meter.

See “Parameter Configuration Using UltraLink Software” on page48 for further details.

HEAT FLOW FOR ENERGY MODEL ONLY

The Energy model allows the integration of two 1000 Ohm, platinum RTDs with the transmitter, effectively providing an instrument for measuring energy consumed in liquid heating and cooling systems. RTDs ordered with the Energy model are factory calibrated and shipped with the transmitter.

The Energy model has multiple heat ranges. Select the range that encompasses the temperature range of your application.

The three-wire surface-mount RTDs are attached at the factory to a plug-in connector. Install the RTDs on or in the pipe as recommended, and then plug the RTDs into the RTD connector in the transmitter.

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 RTDs are available in standard lengths of 20 feet (6 meters), 50 feet (15 meters) and 100 feet (30 meters) of attached shielded cable.

Installing Surface-Mounted RTDs

Use surface-mount RTDs on well insulated pipe. Use insertion (wetted) RTDs on pipes that are not insulated.

1. Select areas on the supply and return pipes where the RTDs will be mounted.

2. Remove or peel back the insulation all the way around the pipe in the installation area.

3. Clean an area slightly larger than the RTD down to bare metal on the pipe.

4. Place a small amount of heat sink compound on the pipe in the RTD installation location. See Figure 35.

5. Press the RTD rmly into the compound. Fasten the RTD to the pipe with the included stretch tape.

6. Route the RTD cables back to the transmitter and secure the cable so that it will not be pulled on or abraded inadvertently.

7. Replace the insulation on the pipe. Check that the RTDs are not exposed to air currents.

Installing Insertion (Wetted) RTDs

OTE:N The hot tap shutoff shown in Figure 36 is customer-supplied.

Insertion RTDs are typically installed through 1/4 inch (6 mm) compression fittings and isolation ball valves.

1. Insert the RTD suciently into the ow 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.

2. Route the RTD cables back to the transmitter and secure the cable so it will not be pulled on or abraded inadvertently.

If the cables are not long enough to reach the transmitter, route the cables to an electrical junction box and add cable from that point. Use three-wire shielded cable, such as Belden® 9939 or equal.

OTE:N Adding cable adds to the resistance the transmitter reads and may

have an effect on absolute accuracy. If cable is added, add the same length to both RTDs to minimize errors due to changes in cable resistance.

Parameter Conguration Using the Keypad

PARAMETER CONFIGURATION USING THE KEYPAD

A transmitter with a keypad can be configured through the keypad interface or by using the Windows-compatible UltraLink software utility. When a USB programming cable is connected, the RS485 and frequency outputs are disabled.

Transmitters without a keypad can only be configured using the UltraLink software utility. See “Parameter Configuration

Using UltraLink Software” on page48 for software details. Of the two methods of configuration, the UltraLink software

utility provides more advanced features and offers the ability to store and transfer meter configurations between similar transmitters. All entries are saved in non-volatile FLASH memory and are retained indefinitely in the event of a power loss.

The transmitter’s keypad is a four-key tactile feedback interface that lets you view and change configuration parameters used by the operating system.

Startup

STARTUP

The TFX Ultra system requires a full pipe of liquid for a successful startup. Do not attempt to make adjustments or change configurations until a full pipe is verified.

OTE:N If you used Dow 732 RTV to couple the transducers to the pipe, make sure the adhesive is fully cured before you try

to take readings. Dow 732 RTV takes 24 hours to cure satisfactorily.

1. Verify that all wiring is properly connected and routed, as described in “Transducer Installation” on page15.

2. Verify that the transducers are properly mounted, as described in “Transducer Installation” on page15.

3. Apply power to the transmitter. The transmitter display will briey show a software version number and then all of the segments will illuminate in succession.

4. Verify that the pipe is full of liquid.

5. Go to SER MENU > SIG STR and conrm that the signal strength is 5…98. If the signal strength is lower than ve, check the transducer mounting methods and liquid/pipe characteristics you entered. If what you entered is correct, you need to recongure the installation to increase the signal strength. For example, change a W-Mount transducer installation to a V-Mount installation. Or change a V-Mount installation to a Z-Mount installation.

OTE:N Mounting configuration changes apply only to DTTR, DTTN, DTTL and DTTH transducer sets.

6. Go to SER MENU > SSPD FPS and SSPD MPS and conrm that the actual measured liquid 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 transmitter is operating properly, see “Parameter Configuration Using the Keypad” on page34 for additional programming features.

CONFIGURATION

Menu Structure

The transmitter’s firmware has a hierarchical menu structure. See “Menu Maps” on page64 for a visual path to the configuration parameters.

The seven menus used in the transmitter firmware are as follows:

Menu Meaning Function

BSC MENU BASIC Contains all of the configuration parameters necessary to initially program the transmitter to measure flow.

CH1 MENU CHANNEL 1 Configures the 4-20 mA output. Applies to both the Flow-Only and Energy models.

CH2 MENU CHANNEL 2

SEN MENU SENSOR Used to select the transducer type such as DTTN or DTTS.

SEC MENU SECURITY Used to reset totalizers, return filtering to factory settings, and revise security level of a password.

SER MENU SERVICE Contains system settings that are used for advanced configuration and zeroing the transmitter on the pipe.

DSP MENU DISPLAY Used to configure transmitter display functions.

The following pages define the configuration parameters located in each of the menus.



Selects the mounting orientation for the transducers based on pipe and liquid characteristics. See “Transducer Installation” on page15 .

Transducer transmission frequencies are specific to the type of transducer and the size of pipe. In general the DTTL 500 kHz transducers are used for pipes greater than 24 inches (600 mm). DTTR, DTTN and DTTH 1 MHz transducers, are for intermediate sized pipes between 2 inches (50 mm) and 24 inches (600 mm). The DTTS and DTTC, 2 MHz transducers, are for pipe sizes between 1/2 inch (13 mm) and 2 inches (50 mm)

Allows the change of the direction the transmitter assumes is forward. When mounting transmitters with integral transducers, this feature allows upstream and downstream transducers to be “electronically” reversed making upside down mounting of the display unnecessary.

If OTHER was chosen as FL TYPE, a FLUID SS will need to be entered. A list of alternate fluids and their associated sound speeds is located in the Appendix located at the back of this manual.

Fluid sound speed may also be found using the Target DBg Data screen available in the UltraLink software utility. See “Target Dbg Data Screen Definitions” on page63.

Allows adjustments to be made to the absolute viscosity of the liquid in centipoise.

Ultrasonic transmitters use pipe size, viscosity and specific gravity to calculate Reynolds numbers. Since the Reynolds number influences flow profile, the transmitter has to compensate for the relatively high velocities at the pipe center during transitional or laminar flow conditions. The entry of FLUID VI is used 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.

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 previously. 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 transmitter will not display a flow rate at flows less than the MIN RATE 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 previously. 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.

A low flow cutoff 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 RATE.

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 transmitter 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 UltraLink software utility.

E0 × 1 (no multiplier) E1 × 10 E2 × 100 E3 × 1000 E4 × 10,000 E5 × 100,000 E6 × 1000,000

As a result, if the MIN RATE is set to a value greater than zero, the transmitter 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 transmitter display will indicate 25. Another example, if the MIN RATE is set to -100 and the actual flow is -200, the transmitter will indicate -100. This can be a problem if the transmitter 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.

4-20 TST 4-20 mA test Allows a simulated flow value to be sent from the 4-20 mA output. By incrementing this value, the 4-20 mA

frequency output on the Flow-Only models.

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 transmitter 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 models. These entries are volumetric rate units that are equal to the volumetric units configured as RATE UNT and RATE INT discussed previously.

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 transmitter 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.

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 model, 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.

Parameter Meaning Options Description

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 transmitters come with the calibration values already entered into the Energy model and should not need to be changed.

Field replacement of RTDs is possible thru the use of the keypad or the UltraLink software utility. If the RTDs were ordered from the manufacturer, they will come with calibration values that need to be loaded into the Energy model.

New, non-calibrated RTDs will need to be field calibrated using an ice bath and boiling water to derive calibration values. See “Replacing

The transmitter performs an actual speed-of-sound calculation for the liquid it is measuring. The calculation varies with temperature, pressure and fluid composition.

The transmitter compensates 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 appears on the display and you must correct the sound speed entry.

The value indicated in SSPD measurement should be within 10% of the value specified 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, there may be 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.

The following table lists sound speed values for water at varying temperatures. If the transmitter is measuring sound speed within 2% of the table values, then the installation and setup of the instrument is correct.

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 transmitter 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.

OTE:N If the transmitter is configured to display totalizer values, the display will alternate between error 0010 and the

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 transmitter is functioning, there is no real advantage to a signal strength of 50 over a signal strength of 10.

The SIG C-OF is used to drive the transmitter 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 transmitter’s 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.

Parameter Meaning Options Description

Substitute Flow SUB FLOW is a value that the analog outputs and the flow rate display will indicate when an error condition in the transmitter 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:

Because every transmitter 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 transmitter’s accuracy. A provision is made using this entry to establish “Zero” flow and eliminate the offset.

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. 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 used. To use 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.

This function can be used to make the transmitter agree with a different (or reference) transmitter 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:

• The transmitter is indicating a flow rate that is 4% higher than another transmitter located in the same pipe line. To make the transmitter indicate the same flow rate as the other transmitter, enter a COR FTR of 0.960 to lower the readings by 4%.

• An out-of-round pipe, carrying water, causes the transmitter to indicate a measured sound speed that is 7.4% lower than the Table 4.5 value. This pipe condition will cause the transmitter to indicate flow rates that are 7.4% lower than actual flow. To correct the flow readings, enter 1.074.

If BAT CH 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.

Transducer Spacing is a value calculated by the transmitter’s 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 DTTR, DTTN, DTTL and DTTH transducers.

Transducer Flow Direction allows the change of the direction the transmitter assumes is forward. When mounting transmitters with integral transducers, use this feature to reverse upstream and downstream transducers, making upside-down mounting of the display unnecessary.

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 transmitter 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. The factory default low signal cutoff is 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 transmitter 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, use:

Conguration Menu

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

Filtering Tab

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

Figure 44: Filtering tab

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 transmitter. Conversely, lowering this value will decrease the response time of the transmitter to changes in flow/ energy rate. This filter is not adaptive, it is operational to the value set at all times.

OTE:N The transmitter 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 transmitter to react faster.

The damping value is increased to increase stability of the flow rate readings. Damping values are decreased to allow the transmitter 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.

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.

Page 53 March 2018 TTM-UM-00136-EN-08

Conguration Menu

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 transmitter 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 transmitter 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 transmitter. Select the appropriate function from the pull-down menu and click Download. When a function is changed from the factory setting, a configuration error 1002 will result. This error will be cleared by resetting the transmitter microprocessor from the Communications/Commands/ Reset Target button or by cycling power on the transmitter. Once the proper output is selected and the microprocessor is reset, calibration and configuration of the modules can be completed.

Figure 45: Output tab

Channel 1, 4-20 mA Configuration

OTE:N The 4-20 mA Output menu applies to all transmitters 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 model.

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 transmitter 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.

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 model. These entries are volumetric rate units that are equal to the volumetric units configured as rate units and rate interval.

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

Page 54 March 2018TTM-UM-00136-EN-08

Conguration Menu

If the transmitter 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 transmitter, 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. Use

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).

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).

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 Configuration for Energy Model Only

OTE:N The Channel 2 Menu is used to configure model specific I/O options. The Flow-Only model presents a different set of

parameters than the Energy model.

IT IS POSSIBLE TO CHOOSE OPTIONS PERTAINING ONLY TO THE FLOWONLY MODEL WHEN AN ENERGY MODEL IS PRESENT. THE OPPOSITE IS ALSO TRUE. THE PROPER MENU TYPE MUST BE CHOSEN FOR THE ACTUAL TRANSMITTER. IF NOT, THE OUTPUTS OR TRANSMITTER 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 transmitters come with the calibration values already entered into the Energy model 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 model.

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 transmitter to enable the changes to take eect.

New, non-calibrated RTDs will need to be field calibrated using an ice bath and boiling water to derive calibration values. See

Remove the Zero Oset

Because every transmitter installation is slightly different and sound waves can travel in slightly different ways through these installations, it is important to remove the zero offset at zero flow to maintain the transmitter’s accuracy. The zeroing process is essential in systems using the DTTS and DTTC transducer sets for accuracy. To establish zero flow and eliminate the offset:

1. Establish zero ow in the pipe (verify 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. Click Set.

Table 12: 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 does not matter in which order the words are sent, as long as the receiving device knows which way to expect it. Since it is 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 is important to make sure it matches the slave endianess for proper data interpretation. The transmitter actually provides two Modbus Register maps to accommodate both formats. This is useful in applications where the Modbus Master cannot be configured for endianness.

Page 88 March 2018TTM-UM-00136-EN-08

Symptoms: Transmitter does not power up.

Possible Causes Recommended Action

• No power or inadequate power

• Blown fuse (AC Model only)

• Display ribbon cable not seated properly

• Measure voltage at the power terminals and check that the voltage matches the labels by the power terminals.

• Check the fuse near the power terminals. If fuse is blown, verify the voltage and polarity is correct and reset the fuse.

• Inspect ribbon cable connections. LED’s on power board will light up – with no LCD display.

• Replace the transmitter if the above actions do not resolve the issue.

Symptoms: Flow reading appears to be incorrect.

Possible Causes Recommended Action

• Incorrect positioning of transducers

• Poor contact between transducers and pipe

• Poor placement of transducers

• Low signal strength

• Process loop issues

• Incorrect pipe settings

• Meter not calibrated?

• Display not set up correctly

Refer to the Transducer Mounting Configuration section for details on proper installation.

At the transducer:

• Verify that the spacing of the transducers is set correctly. On most transducers, a scribe mark on the side of the transducers indicates the point of measurement—NOT from the end points of the transducers.

• Verify that the transducers are aligned correctly. For Z-Mount, verify the transducers are 180° from each other.

• Make sure there is a good contact between the transducers and pipe and a thin coat of acoustic coupling is applied. For integral mount, check for over-tightening of the transducers.

Process loop and general location:

• Make sure the transducers are on the sides of the pipe and NOT on the top of the pipe.

• Check that the transducers are NOT located at the highest point in the loop where air may accumulate.

• Check that the transducers are NOT on a downward flowing pipe unless adequate downstream head pressure is present to overcome partial filling or cavitation.

• Check that the transducers have adequate straight pipe upstream and downstream.

• Check process loop for entrained air or particulates which will impact the flow readings.

• Pipes may develop scale, product build-up or corrosion over time. As a result, the effective wall thickness may be different than a new pipe and wall thickness or liner parameters may need to be adjusted (PIPE WT, LINER T, LINER MA, LINER SS, LINER R).

At the transmitter:

• Verify that parameters match the installation: XDCR MNT, XDCR HZ, PIPE OD, PIPE WT, PIPE MAT, PIPE SS, PIPE R, LINER T, LINER MA, LINER SS, LINER R, FL TYPE, FLUID SS, FLUID VI, SP GRAVITY.

• Check that the SIG STR parameter in the Service Menu (SER MENU) is between 5…98. ◊ If the signal strength is greater than 98, change the mounting to increase the path length.

For example from a Z-mount to V-mount or a V-mount to a W-mount. Repeat the startup and configuration steps.

◊ If the signal strength is less than 5, change the mounting to decrease the path length. For

example from a W-mount to a V-mount or a V-mount to a Z-mount. Repeat the startup and configuration steps.

• Zero the meter. See “DTTS/DTTC Small Pipe Transducer Calibration Procedure” on page88..

Troubleshooting

Symptoms: Unstable flow.

Possible Causes Recommended Action

• Installation issues

• Flow instability

• Transducers mounting is loose

• Transducers are moved

• Check process loop for variations of entrained air which will impact the flow

• Check for pump induced flow instability.

• Ensure the transducers are secure and are in area where the transducers will not be inadvertently bumped or disturbed.

Page 89 March 2018 TTM-UM-00136-EN-08

Troubleshooting

Symptoms: Flow readout is opposite of the flow direction.

Possible Causes Recommended Action

• Integral mount transmitter is mounted in reverse flow direction so display is properly oriented

• Up and down transducers wiring reversedFlow direction parameter is reversed

• Change the transducer flow direction parameter (Basic Menu > FLO DIR).

• Rewire the up and down transducers to the transmitter.

Symptoms: (Energy Models only) Energy reading appears to be incorrect.

Possible Causes Recommended Action

• Incorrect flow readings

• Incorrect temperature reading

Energy is directly calculated from the volumetric flow and temperature difference.

• Verify flow readings are within expected range: ◊ If in PROGRAM mode, press MENU to return to the RUN mode.

• Verify temperatures readings are within expected range: ◊ Service Menu (SER) TEMP 1, TEMP 2 and TEMP DIFF

Refer to symptoms for incorrect flow and temperature readings.

Symptoms: (Energy Models only) Energy reading is opposite of the flow direction.

Possible Causes Recommended Action

• Flow reading is opposite the flow direction

• RTDs mounted in reverse order

• Verify the flow reading is correct. If not, refer to symptom “Flow reading is opposite of the flow direction”.

• If flow reading is correct, then verify RTD readings. ◊ Refer to symptom “Temperature (RTD) reading appears to be incorrect”. ◊ Swap the RTDs mounting locations. ◊ In Rev S or later, change the RTD position parameter from NORMAL to SWAPPED: Basic

Menu (BSC) > RTD POS.

Symptoms: (Energy Models only) Temperature (RTD) reading appears to be incorrect.

Possible Causes Recommended Action

• Incorrect wiring

• Cable issue

• RTD not functioning

• RTD needs recalibration

Refer to Heat Flow for Energy Models Only section for details on proper mounting and wiring.

• Check that the RTDs are properly wired to transmitter (pins RTD1 A and B, RTD2 A and B).

• For surface mount RTDs, verify that RTDs are installed on a well-insulated pipe. Ensure that the surface mounted RTDs have good thermal contact by verifying surface is bare metal and heat sink compound is used.

• Verify that the fluid temperature is within range of the RTD specifications.

• At the transmitter, disconnect the RTD wiring. Measure the resistance between pin #6 and pins #2/4, and between #5 and pins #1/3. The resistance should be 843… 2297 ohms depending on the fluid temperature. The resistance between pins #2 and #4, and #1 and #3 should be less than 5 ohms.

◊ If the measurements are significantly out of range or there appears to be an open or short

in the cable, replace the RTD.

◊ If the RTD appears to be functional, it may need to be recalibrated. See “In-Field Calibration

of RTD Temperature Sensors” on page92.

Symptoms: Current, frequency or pulse outputs do not match the readings.

Possible Causes Recommended Action

• Incorrect parameter settings

• Wiring or control system configuration issues

Verify that the parameters for the output are set properly.

• 4…20 mA: refer to FL 4MA and FL 20MA in the Channel 1 menu

• Frequency output (Flow-only meter): refer to MAX RATE in the Basic Menu (BSC)

• Totalizing pulse: refer to TOT MULT and TOTL E in the Basic Menu (BSC) for proper configuration. The pulse output is limited to one pulse per second. For frequency or pulse outputs, verify the proper switch settings, ground reference, voltage source and load compatible with the control system. Refer to Inputs/Outputs for proper wiring.

Heating and Cooling Measurement

HEATING AND COOLING MEASUREMENT

The Energy model 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

QKdV

Where:

Q = Quantity of heat absorbed V = Volume of liquid passed

K = Heat coefficient of the liquid

θ = Temperature difference between supply and return

The RTD temperature measurement circuit in the Energy model 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 transmitter without influencing system accuracy or stability.

The Energy model allows integration of two 1000 Ohm platinum RTDs with the energy transmitter, effectively providing an instrument for measuring energy delivered in liquid cooling and heating systems. If RTDs were ordered with the energy transmitter, 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 UltraLink software utility. If the RTDs were ordered from the manufacturer of the Energy model, they will come with calibration values that need to be loaded into the Energy model.

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.

5. Insert both RTD temperature sensors and the laboratory grade thermometer into either the ice bath or the boiling water bath and allow about 20 minutes for the sensors to come up to the same temperature.

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.
