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.

OTE:N All control outputs are disabled when a USB cable is connected.

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.

K factor

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.

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.
