PART 1 - INTRODUCTION
General
The TFXM ultrasonic flow meter is designed to measure the fluid velocity of liquid within closed conduit. The transducers are a non-contacting, clamp-on type, which will provide benefits of non­fouling operation and ease of installation.
TFXM transit time flowmeters utilize two transducers that function as both ultrasonic transmitters and receivers. The transducers are clamped on the outside of a closed pipe at a specific distance from each other . The transducers can be mounted in V-mode where the sound transverses the pipe two times, W-mode where the sound transverses the pipe four times, or in Z-mode where the transducers are mounted on opposite sides of the pipe and the sound crosses the pipe once. This selection is based on pipe and liquid characteristics. The flowmeter operates by alternately transmitting and receiving a frequency modulated burst of sound energy between the two transducers (contrapropogation) and measuring the time interval that it takes for sound to travel between the two transducers. The difference in the time interval measured is directly related to the velocity of the liquid in the pipe.
Application Versatility
The TFXM flow meter can be successfully applied on a wide range of metering applications. The simple to program transmitter allows the standard product to be used on pipe sizes ranging from 2 - 100 inch [ 50 - 2540 mm ] pipe. A variety of liquid applications can be accommodated: ultrapure liquids, potable water, chemicals, raw sewage, reclaimed water, cooling water, river water, plant effluent, etc. Because the transducers are non­contacting and have no moving parts, the flow meter is not affected by system pressure, fouling or wear. Standard DTTN transducers are rated to 300?F [150?C]. Temperatures to 450?F
[230?C] can be accommodated with Series DTTH transducers. Please consult the Dynasonics factory for assistance.

PART 1 - TRANSMITTER INSTALLATION
Transmitter Installation
After unpacking, it is recommended to save the shipping carton and packing materials in case the instrument is stored or re­shipped. Inspect the equipment and carton for damage. If there is evidence of shipping damage, notify the carrier immediately.
The enclosure should be mounted in an area that is convenient for servicing, calibration or for observation of the LCD readout.
1. Locate the transmitter within the length of transducer cable
that was supplied with the TFXM system. If this is not possible and additional cable is to be added to the transduc­ers, utilize RG59 (75 Ohm) cable and splices. Ensure that both cables are of equal length . If additional cable cannot be added in the field, contact the Dynasonics factory to coordinate an exchange for the proper cable length. Transducer cables that are up to 990 feet [300 meters] are available.
2. Mount the TFXM transmitter in a location that is:
? ? Where little vibration exists. ? ? Protected from falling corrosive fluids. ? ? Within ambient temperature limits -40 to 185°F [-40 to 85°C] ? ? Out of direct sunlight. Direct sunlight may increase
temperatures within the transmitter to above the maximum limit.
3. Mounting: Refer to Figure 1.3 for enclosure and mounting
dimension details. Ensure that enough room is available to allow for maintenance and conduit entrances. Secure the enclosure to a flat surface with four appropriate fasteners.
4. Conduit holes. Conduit hubs should be used where cables
enter the enclosure. Holes not used for cable entry should be sealed with plugs.
NOTE: Use NEMA 4 [ IP65 ] rated fittings/plugs to maintain the water tight integrity of the enclosure. Generally, the left conduit hole (viewed from front) is used for line power; the center conduit holes for transducer connections and the right hole s are utilized for I/O wiring.

To access terminal strips for electronic connections, loosen the six screws in the wiring access panel located on the bottom of the en­closure.
1. Guide the transducer cables through the transmitter conduit holes located in the bottom of the enclosure. Secure the transducer’s flexible conduit with the supplied conduit nut (if flexible conduit was ordered with the transducer) or tighten the cord grip on the coaxial cable.
2. The terminals within TFXM are a screw terminal type. Connect the appropriate wires to the corresponding screw terminals in the transmitter. Observe UP/DOWN and CH1 or CH2 orientation. CH1 and CH2 correspond to the measuring chan­nels contained within the TFXM flow meter. DTFXM1 flow me-

ters only have one measuring channel, so transducers will only be connected to the CH1 terminals. DTFXM2 flow meters have two measuring channels, so transducers will be con­nected to both the CH1 and CH2 terminals. See Figure 1.4. Secure wires by tightening to between 0.5 and 0.6 Nm of torque.
NOTE: The transducer cable s carry low level signals. It is typi­cally not recommended to add additional cable to the factory sup­plied coaxial cables. If an exchange is not possible and additional cable is to be added to the transducers, utilize RG59 (75 Ohm) cable and splices. Ensure that both cables are of equal length. If additional cable cannot be added in the field, contact the Dynasonics factory to coordinate an exchange for the proper cable length. Cables to 990 feet [ 300 meters ] are available.
Connect line power to the two screw terminals marked AC IN and the one marked GROUND in the transmitter. See Figure 1.4. Utilize the conduit hole on the left side of the enclosure for this purpose. Use wiring practices that conform to local codes (National Electric Code Hand book in the USA). Use only the standard three wire connection. The ground terminal grounds the instrument, which is mandatory for safe operation.
CAUTION: Any other wiring method may be unsafe or cause improper operation of the instrument.
It is recommended not to run line power with other signal wires within the same wiring tray or conduit.
NOTE: This instrument requires clean electrical line power. Do not operate this unit on circuits with noisy components (i.e. Fluorescent lights, relays, compressors, variable frequency drives, etc.).
The TFXM can be operated from a 10-28 Vdc source, as long as it is capable of supplying at least 8 Watts. DC power is connected to the screw terminals labeled +DC IN and –DC IN on the terminal block located on the left side of the enclosure. Observe proper polarity in making these connections . It is recommended that a 1 A fuse be installed in DC connections to protect the TFXM and

the battery source from damage should a fault occur. See the Wiring Diagram located at Figure 1.4.
Both AC and a 12 VDC battery power can be connected to the TFXM to facilitate an uninterruptible power source to the flow me­ter. The flow meter will operate on the AC power source until AC power is interrupted—at that point the flow meter will continue to operate on the battery until AC power is restored. In this configu­ration the battery will not be trickle-charged by the TFXM. Batter­ies are rated in Amp Hour capacity. Select a battery that can maintain operation of the flow meter for the length of anticipated AC power outages.
Example: The TFXM draws approximately 700 mA of current at 12 VDC. A 7 Amp Hour 12 Volt battery will be able to operate the TFXM for approximately 7 Amp Hours / 0.7 Amps = 10 Hours.
As an alternate uninterruptible configuration, connect a battery to the TFXM as the primary source of power and permanently con­nect a trickle-charger to the battery. Ensure that the trickle­charger is rated to output a minimum of 10 Watts.
Rev. 8/02 -1.12- TFXM
PART 1 - INPUT/OUTPUT CONFIGURATION
General
DIP-Switch Configuration
4-20 mA Output Configuration
Series TFXM contains integrated RS485 communications, one 4­20 mA output per measurement channel and two SPDT relays per measurement channel. Other auxiliary input/output options are available. All outputs are 2,500 V optically isolated from TFXM power and Earth grounds -- eliminating the potential for ground loops and reducing the chance of severe damage in the event of an electrical surge.
Auxiliary options that are available include: secondary 4-20 mA, secondary dual-relay, rate pulse, RS232C, a 200,000-event datalogger and BTU-Pro heat-delivered option. In order for an Auxiliary output option to be operational, either the 4-20mA or the dual-relays must be disabled for that measurement channel. All outputs are field configurable by utilizing the keyboard or ULTRALINK interface. Field wiring connections to the outputs are made to the terminal blocks located within the wiring access panel.
The two, three-position DIP-switches located within the wiring ac­cess panel configure the TFXM for input/output options. The flow meter is shipped from the Dynasonics factory with the options or­dered configured and installed. Typically no adjustments to these switches are necessary. The switch lever to the left in each DIP switch block is utilized to configure the 4-20 mA output as either internally or externally powered. The other two switches in each DIP-switch block are used to disable either the 4-20 mA or dual­relay output should an Auxiliary output be installed within the TFXM enclosure.
The 4-20 mA Output interfaces with virtually all recording and logging systems by transmitting an analog current signal that is proportional to system flow rate. The output can be configured to be either internally or externally powered by setting the left DIP ­switch at SW1 for Channel 1 and SW2 for Channel 2. Refer to the Field Wiring Diagram at Figure 1.4 for terminal block and DIP­switch locations.
When powered from internal power, the 4-20 mA output can pro­vide loop current for a maximum of 800 ohms of total loop resis­tance. When powered externally, the maximum load varies with the level of the voltage source. The insertion loss of the 4-20 mA circuit is 5Vdc, so the maximum loop load that can be powered is calculated by the equation:
Rev. 8/02 -1.13- TFXM
PART 1 - INPUT/OUTPUT CONFIGURATION
Max Loop Load = (External Supply Voltage - 5)
0.02
Cable used to transmit 4-20 mA signals should be routed in wiring trays or conduits that carry instrumentation signals. It should not be run with AC power or other potential sources of noise. Very long cables can be accommodated, but the resistance of the wire must be added to the total loop load to ensure that adequate power is available to power the load. Shielding of the wires carry­ing 4-20mA signals are typically not necessary, but is recom­mended when wires must be run past or in proximity of electrically noisy circuits.
Control Relays Configuration
RS485 Configuration
Two independent SPDT (single-pole, double-throw, Form C) relays are integrated into the TFXM for each measuring channel installed within the flow meter enclosure. The relay operations are user configured via software to act in a flow rate alarm, signal strength alarm or totalizer/batching mode. See Figure 1.4 for ter- minal block locations. The relays are rated for 200 Vac max. and have a current rating of 0.5 A resistive load [175 Vdc @ 0.25 A resistive]. It is highly recommended that a slave relay be utilized whenever the control relays are used to control inductive loads such as solenoids and motors.
An RS485 driver and Modbus protocol is utilized by the TFXM to communicate between the two channels located within the TFXM flow meter enclosure (if so equipped), communicate with satellite TFX flow meters and to interface with a personal computer sys­tem. The TFXM can be used as the Primary meter (Master) to program other Secondary (Slave) meters located on the RS485 network. The TFXM contains a feature that permits up to 8 flow measurement channels to be mathematically manipulated. Soft­ware configuration is covered in Section 4 of this manual.
RS485 interconnections are made at the terminal block located within the TFXM Field Wiring Access Panel. See Figure 1.4. Util­ize two conductor plus shield wiring cable for this purpose. Avoid running these cables in wiring trays or conduits carrying AC power or other electrically noisy devices.

PART 2 - TRANSDUCER POSITIONING
General
The transducers that are utilized by the Series TFXM contain piezoelectric crystals for transmitting and receiving ultrasound signals through walls of liquid piping systems. DTTN and DTTH transducers are relatively simple and straight-forward to install, but spacing and alignment of the transducers is critical to the system's accuracy and performance. Extra care should be taken to ensure that these instructions are carefully executed.
Mounting of the DTTN and DTTH clamp-on ultrasonic transit time transducers is comprised of four steps. In general, these steps consist of:
1. Selection of the optimum location on a piping system.
2. Entering the pipe and liquid parameters into either the optional software utility (UltraLink) or keying in the parameters into the TFXM keypad. The software embedded in UltraLink and TFXM will calculate proper transducer spacing based on these entries.
3. Pipe preparation and transducer mounting.
1. Mounting Location
The first step in the installation process is the selection of an optimum location for the flow measurement to be made. For this to be done effectively, a basic knowledge of the piping system and its plumbing are required.
An optimum location would be defined as a piping system that is completely full of liquid when measurements are being taken and has lengths of straight pipe such as those described in TABLE 2.1. The optimum straight pipe diameter recommendations apply to pipes in both horizontal and vertical orientation.
TFXM transit time flowmeters utilize two transducers that function as both ultrasonic transmitters and receivers. The transducers are clamped on the outside of a closed pipe at a specific distance from each other. The transducers can be mounted in V-mode where the sound traverses the pipe two times, W-mode where the sound traverses the pipe four times, or in Z-mode where the transducers are mounted on opposite

sides of the pipe and the sound crosses the pipe once. See Figures 2.1 -2.3. This selection is based on pipe and liquid
characteristics. The flowmeter 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

*If the liquid to be measured is high in TSS (total suspended solids) or aerated, more than likely the installation will require configuration and setup in the next category lower than the recommendations in this chart. For example, if the pipe is 10-inch (250 mm) carbon steel and the liquid contains concentrations of suspended solids, a Z -mode will probably yield the best performance results, not the V-mode suggested in the chart.

3. Transducer Mounting
After selecting an optimal mounting location, Step 1, and suc­cessfully determining the proper transducer spacing, Step 2, the transducers can now be mounted onto the pipe.
The DTT transducers need to be properly oriented on the pipe to provide optimum reliability and performance. On horizontal pipes, the transducers should be mounted 180 radial degrees from one another and at least 45 degrees from the top-dead­center and bottom-dead-center of the pipe. See Figure 2.5.
Figure 2.5 does not apply to vertically oriented pipes.

eas slightly larger than the flat surface of the transducer heads must be cleaned of all rust, scale and moisture. Finish the sur­face with some emery paper, and wipe the surface with a de­greasing solvent such as trichlorethylene. 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.
PART 2 - TRANSDUCER POSITIONING
Installation on Large Pipes
Mounting Transducers in Z-Mount Configuration
Installation on larger pipes requires careful measurements to the linear and radial placement of the DTT transducers. Failure to properly orient and place the transducers on the pipe may lead to weak signal strength and/or inaccurate readings. The section below 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.
Wrap the paper around the pipe in the manner shown in Figure
2.6. Align the paper ends to within 0.25 inches [6mm].
Figure 2.6 Paper Template Alignment
Mark the intersection of the two pieces of paper to indicate the circumference. Remove the template and spread it out on a flat surface. Fold the template in half, bisecting the circumference. See Figure 2.7.
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 2.5 for acceptable radial orientations. Wrap the template back around the pipe, placing the beginning of the pa­per and corner in the location of the mark. Move to the other side of the pipe and mark the ends of the crease. Measure from the end of the crease (directly across the pipe from the first

transducer location) the dimension derived in Step 2, Trans­ducer Spacing. Mark this location on the pipe.
The two marks on the pipe are now properly aligned and meas­ured.
Figure 2.7 Bisecting the pipe circumference
If access to the bottom of the pipe prohibits the wrapping of the paper around the circumference, cut a piece of paper to these dimensions and lay it over the top of the pipe.
Length = Pipe O.D. x 1.57 Width = Spacing determined on Pages 2.14 or 2.16
Mark opposite corners of the paper on the pipe. Apply trans­ducers to these two marks.
Rev. 8/02 - 2. 19 - TFXM
PART 2 - TRANSDUCER POSITIONING
Transducer Mounting
1. Place a single bead of couplant, approximately 3/8 inch [6 mm] thick, on the flat face of the transducer. See Figure
2.8. Use Dow 732 for permanent and Dow 44 or Dow 111 for temporary (less than 12 months) installations. [For high temperature installations, utilize the Dow 112 and orange silicone pads that were shipped with the DTTH transduc­ers. Apply the couplant to the transducer face as shown in Figure 2.8, then place the silicone pad over the couplant. Apply the couplant to the exposed surface of the silicone pad.
Figure 2.8 Transducer Couplant Application
2. Install the first transducer on the pipe, with the alignment groove placed over one of the marks created in the previ­ous section. The stainless steel clamping band will be po­sitioned within the groove on the front of the transducer. See Figure 2.9.
Rev. 8/02 - 2. 20 - TFXM
PART 2 - TRANSDUCER POSITIONING
Lineal measurements are made from these lines.
Figure 2.9 Z-Mode Transducer Mounting
3. Secure the transducer by tightening the stainless steel strap. (Excessive pressure is not required. Apply just enough pressure so that the couplant fills the gap between the pipe and transducer.) If DOW 732, or some other sili­cone RTV type sealant, was used ensure that no relative movement between the transducer and pipe takes place during the setting time and do not apply instrument power for at least 24 hours. If Dow 44 or Dow 111 or an alternate form of grease has been used as a couplant, setting time is not necessary.
4. Mount the transducer in the same manner as the first, but at the second mark on the pipe. Slide the transducer clamp over the transducer and secure with the stainless strap. Re­fer to Figure 2.9 for proper orientation.
NOTE: Since pipes larger than 20 inches (500 mm), typically can be out-of-round by a substantial amount, it is advised that the second transducer be left loose so that it can be positioned at the location of greatest Signal Strength. See Section 3 of this manual for Diagnostics and Signal Strength Measurement. Maximum Signal Strength can typically be obtained within 1 inch [25 mm] of the calculated lineal distance.

Mounting Track Installation
Mounting Track Installation
1. Install the single mounting track on the pipe in an orienta­tion suggested by Figure 2.5 (minus the rail mounted across the pipe) with the stainless steel bands provided. Orientation on vertical pipe is not critical. Ensure that the track is parallel to the pipe and that all four mounting feet are touching the pipe.
2. Slide the two transducer clamp brackets towards the cen­ter, 5 inch [125 mm] mark, on the mounting rail.
3. Place a single bead of couplant, approximately 3/8 inch [6 mm] thick, on the flat face of the transducer. See Figure
2.10. Use Dow 732 for permanent and Dow 44 for tempo­rary (less that six months) installations. [High temperature installations require the use of Dow 112 and silicone pads.]
Figure 2.10 Transducer Couplant Application
4. Place the first transducer in between the mounting rails near the zero point on the mounting rail scale. Slide the transducer clamp over the transducer. Adjust the clamp/ transducer such that the notch in the clamp aligns with zero on the scale. See Figure 2.11.

5. Secure with the thumb screw. Ensure that the screw rests in
the counter bore on the top of the transducer. (Excessive pressure is not required. Apply just enough pressure so that the couplant fills the gap between the pipe and transducer.) If DOW 732 or some other silicone RTV type sealant was used, ensure that no relative movement between the trans­ducer and pipe takes place during the setting time and do not apply instrument power for at least 24 hours. If Dow 44 or Dow 111 or an alternate form of grease has been used as a couplant, setting time is not necessary.
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.

PART 3 - STARTUP AND CONFIGURATION
Before Starting the Instrument
Instrument Startup
Note: The TFXM flow meter system requires a full pipe of liquid before a successful startup can be completed. Do not
attempt to make adjustments or change configurations until a full pipe is verified.
Note: If Dow 732 RTV was utilized to couple the transducers to the pipe, the adhesive must fully cure before power is applied to the instrument. Dow 732 requires 24 hours to cure satisfactorily. If Dow 111 silicone grease was utilized as a couplant, the curing time is not required. [DTTH—High Temperature Transducers util­ize Dow 112 couplant and orange silicone pads mounted between the transducer and the pipe. This setup does not require any cur­ing time.]
Procedure:
1. Verify that all wiring is properly connected and routed as described previously in this manual.
2. Verify that the transducers are properly mounted as described in Part 2 of this manual.
3. Apply power to the flow meter. The TFXM display backlighting will illuminate and the software version number will appear on the display.
4. Confirm that Signal Strength is greater than 2% for each measurement channel. If it is not, verify that proper transducer mounting methods and liquid/pipe characteristics have been entered. The pipe must be full of liquid in order to make this measurement.
5. Verify that the actual measured Sound Speed of the liquid is within 0.5% of the table value utilized in the BASIC menu setup.
6. Once the meter is properly operating (proper signal strength and measured sound speed has been achieved) , refer to the later portions of this manual section for additional programming features.

NOTE: The Maximum Rate may be set anywhere in the flow measurement range of -40 to +40 FPS. For example: If bi­directional flow needs to be logged, set the MIN RATE at a negative value and MAX RATE at a positive value.
FL C-OFF - Low Flow Cut -off
Percent of MAX RATE A Low Flow Cut-off entry is provided to allow very low flow
rates (that can be present when pumps are off and valves are closed) to be displayed as Zero flow. Typical values that should be entered are between 1.0% and 5.0% of full-scale.
DAMP PER - System Damping
Relative Percent Entry DAMP PER 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 (typically ±5% of flow rate) , the Flow Filter adapts by decreasing and allows the meter to react faster. Increasing this value tends to provide smoother steady-state flow readings and outputs. The DAMP PER setting increases and decreases the response time of the flow meter display and outputs. Enter a value between 1 and 100 percent, a setting of 1 having the fastest response and 100 having the slowest response.

The 4-20 mA Output interfaces with virtually all recording and logging systems by transmitting an analog current signal that is proportional to system flow rate. The output can be configured to be either internally or externally powered by setting the left DIP-switch at SW1 for Channel 1 and SW2 for Channel 2 . Re­fer to the Field Wiring Diagram at Figure 1.4 for terminal block and DIP-switch locations.
When powered from internal power, the 4-20 mA output can provide loop current for a maximum of 800 ohms of total loop resistance. When powered externally, the maximum load varies with the level of the voltage source. The insertion loss of the 4­20 mA circuit is 5Vdc, so the maximum loop load that can be powered is calculated by the equation:
Max Loop Load = (External Supply Voltage - 5)

4-20mA Span
Rev. 8/02 -3.15- TFXM

These entries are volumetric rate units that are equal to the volumetric units configured as Engi­neering Rate Units and Engineering Units Time Interval entered on page 3.10. These entries may be entered anywhere in the flow measurement range of the instrument (velocity range of – 40 to +40 FPS [-12 to +12 MPS]).
For example, to span the 4-20mA output from –100 GPM to +100 GPM, with 12mA being 0 GPM, set the FL 4MA and FL 20MA inputs as follows:
FL 4MA = -100.0

The 4-20mA ISO-MOD is factory calibrated and should not re­quire adjustment unless it is replaced.
NOTE: The CAL 4MA and CAL 20MA entries should not be used in a attempt to set the 4-20mA range. Utilize FL 4MA and FL 20MA, detailed above, for this purpose.
The CAL4MA entry allows fine adjustments to be made to the “zero” of the 4-20mA output. To adjust the 4mA output, an ammeter or reliable reference connection to the 4-20mA output must be present.
Procedure:
1. Disconnect one side of the current loop and connect the ammeter in series (disconnect either wire at the terminals labeled 4-20mA IN or 4-20mA OUT, Fig. 1.4).
2. Using the arrow keys, increase the numerical value to in­crease the current in the loop to 4mA. Decrease the value to decrease the current in the loop to 4mA. Typical values range between 40-80 counts.
Re connect the 4-20mA output circuitry as required.

Two independent SPDT (single-pole, double-throw, Form C) relays are integrated into the TFXM for each measuring chan­nel installed within the flow meter enclosure. The relay operations are user configured via software to act in either a flow rate alarm, signal strength alarm or totalizer/batching mode. See Figure 1.4 for terminal block locations. The relays are rated for 200 Vac max. and have a current rating of 0.5 A resistive load [175 Vdc @ 0.25 A resistive]. It is highly recommended that a slave relay be utilized whenever the con­trol relays are used to control inductive loads such as solenoids and motors.

When one of the relays is set to TOTALIZE mode, an entry of TOT MULT must be programmed to establish the accumulated flow volume that needs to pass before the relay will “pulse”. The relay will pulse every time that volume is accumulated. The pulse has a duration of approximately 50mSec. Enter a value using the same units that were established as Engineer­ing Units TOTAL on page 3.12.
When a relay is set to FLOW mode, two entries must be made: ON and OFF. The ON and OFF entries dictate at what volu­metric flow rate (using the volumetric units established as Engi­neering Units RATE and RATE INTERVAL on page 3.12) the relay turns ON and at what flow rate the relay turns OFF - es­tablishing a deadband. For “fail-safe” mode, the ON setting should be set higher than the OFF setting.
When a relay is set to SIG STR mode, the relay will activate when the measured Signal Strength falls below the Signal Strength Cutoff setting. See page 3.26.
When a relay is set to ERROR mode, the relay will activate when any error occurs in the flow meter that has caused the meter to stop measuring reliably. See the Appendix of this manual for a list of potential error codes.

The Rate Pulse Output Module is utilized to transmit informa­tion to external counters and PID systems via a frequency out­put that is proportional to system flow rate. Independent Zero and Span settings are established in software using the Flow Measuring Range entries. These entries can be set anywhere in the –40 to +40 FPS [-12 to +12 MPS] measuring range of the instrument. Output resolution of the module is 12-bits (4096 discrete points) and the maximum output frequency setting is 2,500 Hz. The 0.21-Ohm FET output is rated to operate at 100 V and 1 A maximum. This module does not source an output voltage and should be treated as an open collector type of out­put. An external voltage source and limit resistor must be pre­sent.
The FL 100H and FL FL10KH entries are used to set the span of the 0-2.5KHz frequency output. These entries are volumet­ric rate units that are equal to the volumetric units configured as Engineering Rate Units and Engineering Units Time Interval entered on page 3.12. These entries may be entered any­where in the flow measurement range of the instrument (velocity range of –40 to +40 FPS [-12 to +12 MPS]).
For example, to span the 0-2.5KHz output from –100 GPM to +100 GPM, with 1.25KHz being 0 GPM, set the FL 100H and FL 10KH inputs as follows:

7. SERVICE MENU
The SERVICE Menu makes available two different system measurements that are used for trouble -shooting and fine tun­ing of the instrument. Actual liquid sound speed and system signal strength readings can be accessed through this menu. The SERVICE Menu also has features that allow adjustment of Signal Strength Cutoff, Error -Mode outputs and Zero Flow Rate Set.
SSPD MPS - Sound Speed in the Liquid Metric SSPD FPS - Sound Speed in the Liquid U.S.
The TFXM performs an actual speed of sound calculation for the liquid it is measuring. This speed of sound calculation will vary with temperature, pressure and fluid composition. The value indicated in this measurement should be within a couple of percent of the value entered/indicated in the BASIC menu item FLUID SS. (This value cannot be edited.) If the actual measured value is significantly different than the BASIC MENU’s FLUID SS value, it typically indicates a problem with the instrument setup. An entry such as PIPE O.D. or wall thick­ness was probably entered in error, the pipe may not be round, or the transducer spacing is not correct. Table 3.1 lists sound speed values for water at varying temperatures. If the TFXM is measuring sound speed within 0.5% of the table values, the installation and setup of the instrument is proper and accurate readings can be assured.

SIG STR - Signal Strength
Signal Strength
The measurement of Signal Strength assists service personnel with troubleshooting the TFXM system. In general, expect the signal strength readings to be greater than 5% on a full pipe with the transducers properly mounted. Signal strength read­ings that are less than 5% may indicate a need to chose an al­ternative mounting method for the transducers or that an im­proper pipe size has been entered.
Signal Strength readings in excess of 95% may indicate that a mounting method with a longer path length may be required. For example, if mounted on a 3 inch PVC pipe in V-mode causes the measured Signal Strength value to exceed 95%, change the mounting method to W-mode for greater stability in readings.

PART 3 - KEYPAD CONFIGURATION
Signal Strength Cutoff
Signal Strength Cutoff
Signal Strength Cutoff SIG C-OF is used to drive the flowmeter and its outputs to a zero flow state should conditions occur that cause low signal strength. A signal strength indication of be­tween 0.5 and 0.8 is considered to be inadequate for measur­ing flow reliably, so typical settings for SIG C-OF are in the range of 1.0 to 2.0.
Signal Strength indication of 0.5 to 0.8 is considered to be no signal at all. Verify that the pipe if full of liquid, the pipe size and liquid parameters are entered correctly and that the transducers have been mounted accurately.
Substitute Flow
Substitute Flow Entry
Substitute Flow or SUB FLOW is a value that the analog out­puts will be driven at when an error condition in the flowmeter occurs. Typical settings are either –5% or 105% - a value out­side of the normal operating range that can be used to indicate a fault condition to the target device.

Because every flowmeter installation is slightly different and sound waves can travel in slightly different ways through these various installations, a provision is made in this entry to estab­lish “Zero” flow—SET ZERO.
To zero the meter:
1. The pipe must be full of liquid.
2. Flow must be absolute zero—verify by closing a valve se­curely. Allow time for any settling to occur.
3. Press ENTER, use the arrow keys to make the display read YES.

This func­tion can also be utilized to correct an inadvertently entered or erroneous SET ZERO entry.
Universal Correction Factor
COR FTR - Universal Correction Factor
This function can be used to make the TFXM system agree with a different or reference flow meter, by applying a correc­tion factor/multiplier to the readings and outputs. A factory cali­brated system should be set to 1.000. The range of settings for this entry is 0.500 to 1.500. The following examples describe two uses for the COR FTR entry.
?? The TFXM meter is indicating a flow rate that is 4% higher
than another flow meter located in the same pipe line. To make the TFXM indicate the same flow rate as the other meter, enter a COR FTR of 0.960, to lower the readings by 4%.

?? Low Flow Cutoff is entered as a percentage between MAX
Flow and MIN Flow and influences how the flow meter will act at flows very near zero. Generally, an entry of 1% provides for a stable zero indication, while providing a 100:1 turndown ratio for measurements.
?? Low Signal Cutoff is a relative value that should be entered
after a successful flow meter startup. For an initial value, enter 5% [Signal Strength indications below 3% are considered to be below the noise ceiling and should not be indicative of a successful flow meter startup.] The entry has three purposes: It provides an error indication—Low Signal Strength [Error 0010 on the TFXM display] when liquid conditions within the pipe have changed to the point where flow measurements may not be possible. It warns if the pipe’s liquid level has fallen below the level of the transducers. It can also signal that something with the flow meter installation or configuration may have changed. Examples would include such things as the couplant used to mount the transducer has become compromised, a cable has become disconnected or a pipe size setting has been altered.
?? Substitute Flow is used to provide an indication and output
that signifies that an error exists with the flow meter or its setup. It is set as a percentage between MIN Flow and MAX Flow. In a uni-directional 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 out where to set the Substitute Flow value in a bi-directional system perform the following operation:

?? Short Pulse Duration is a function used on pipes larger than
8 inches [200 mm]. Set this value to zero to disable the function. Do not select the Auto Short Pulse box.
?? 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 Flow Filter adapts by decreasing and allows the meter to react faster. 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 whereby if the flow varies within that window, greater Flow Filter Damping will occur. The filter also establishes a flow rate window where measurements outside of the window are captured by the Bad Data Rejection Filter. The value is entered as a percentage of actual flow rate.
Rev. 8/02 -4.8- TFXM
SOFTWARE UTILITIES
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 low flow rates, where the “of rate” Flow Filter Hysteresis is very small and ineffective. This entry is entered in pico-seconds and is differential time. This value is factory set and should not be altered without consulting the Dynasonics technical services department.
?? Flow Filter Sensitivity allows configuration of how fast the
Flow Filter Damping will adapt in the positive direction.
Increasing this value allows greater damping to occur faster than lower values. Adaptation in the negative direction is not user adjustable.
?? Bad Data Rejection is a value related to the number of
successive readings that must be measured outside of the Flow Filter Hysteresis and Flow Filter MinHysteresis windows before the flow meter will use that flow value. Larger values are entered into the Bad Data Rejection when measuring liquids that contain gas bubbles, as the gas bubbles tend to disturb the ultrasonic signals and cause more extraneous flow readings to occur. Larger Bad Data Rejection values tend to make the flow meter more sluggish to rapid changes in actual flow rate.

The screen shown in Figure 4.10 allows multiple actual flow rates to be run past the meter and the values recorded by the TFXM. To calibrate a point, establish a stable, known flow rate (verified by a real-time primary flow instrument), enter the actual flow rate in the Figure 4.10 window and press the Set button. Repeat for as many points as desired. Note: If only two points are to be used (zero and span), it is preferred that a flow rate as high as anticipated in normal operation is used as the calibration point. If an erroneous data point is collected, the point can be removed by pressing the Edit button, selecting the bad point and selecting Remove.
Press the Finish button when all points have been gathered.

MULTICHANNEL OPERATION
General Information
Multiple Channel Display Configuration
Series TFXM is a multiple channel flow meter designed with maxi­mum user flexibility in mind. The product can be configured as a simple flow meter, showing flow on multiple pipe simultaneously. It can also be used to perform mathematical manipulation of flow rates between pipes using its powerful, yet simple to use, algo­rithms. This manual will provide instructions as to configuration of the TFXM in the following scenarios:
1. Multiple Pipe Flow Network
2. Multiple Path Flow Averaging
3. Flow Summations of Multiple Pipes
4. Flow Differences of Multiple Pipes
5. Leak Detection in Pipe Lines
Configuring of the graphics display
The graphics display on the TFXM can be configured to show ei­ther two or four lines of information. This information can be dis­played for any flow meter on the TFXM RS485 network. The pro­cedure to configure the display is as follows:
1. Menu Item 8 can be accessed to select either two or four lines of display information. See Page 3.29 for details.
2. Press the (soft)Select key on the right side of the graphics dis­play to highlight the upper most display entity.
3. Utilize the soft(CHAN) keys UP/DOWN arrows to select what measuring entity is required: Flow RATE, Net TOTAL, Temp Difference, Temp 2, Temp 1, Signal Strength or liquid Sound Speed.
4. Utilize the CHANNEL key to select which measurement chan­nel on the flow meter network is to be displayed:
M = Master Measurement 1 = Secondary Channel (Slave 1) integral to DTFXM2 2, 3, 4...119 = Secondary Channels (Slaves) external to DTFXM No Designation = Multichannel Manipulated Value
5. After the entity and measurement channel have been selected for a particular line, press the (soft)SELECT key to move the

highlighting to the next line of the display. Pressing the (soft) SELECT key on the bottom line of the display will cause the display configuration to end and the setup will be saved.
Multiple Pipe Configuration
Multiple Pipe Flow Network
The TFXM is designed to be the Primary (Master) flow controller in a network of Secondary (Slave) flow meters. The TFXM can be used to display flow information and configure up to 119 satellite flow meters connected on its RS485, two-wire network.
To configure a multiple pipe setup, follow the entries shown in Figure 5.1 . The Primary board in the TFXM is established as the Master and all of the Secondary boards are considered slaves. The coefficient values located on the bottom of the window do not have a bearing on the display, because manipulated display

Multiple Path Configuration
Figure 5.1
Configuration for Multiple Pipe Readings
Multiple Path Flow Meter
By applying more than one set of transducers radially around a pipe, accuracy can be improved in conditions where optimum straight pipe diameters are not available. Typical installations only involve two paths, but on large pipes several paths could be employed. See Figure 5.2 . Only one multiple path system is
permitted per flow measurement network.
To configure the flow meter for multiple path operation, apply the transducers radially around the pipe and apply equal coefficients to each channel that total up to 1.00. For two path systems, 0.50 +0.50 = 1.00; for three path systems 0.333+0.333+0.334 = 1.000; etc.

Difference Flow Meter
The difference of two pipes can be utilized to measure the flow in two pipes and calculate the flow rate in a third trunk line in a pip­ing system. (The difference meter can also be applied to two ends of a piping system to display an alarm to leak between the two measuring points.) Apply a coefficient of +1.00 to one chan­nel and a coefficient of –1.00 to the second channel. The sum of the two manipulated values will be the difference in the flow rates. See Figure 5.4.
