Apply acoustic couplant grease to the downstream transducer and press it onto the pipe using hand pressure at the lineal distance calculated in Step 1. E. Move the transducer slowly around the mounting area until the highest signal strength is observed. Secure with a mounting strap at this location. DTTS and DTTC Transducers A.
PART 1 - INTRODUCTION General The TFXP ultrasonic flow meter is designed to measure the fluid velocity of liquid within closed conduit. The transducers are a noncontacting, clamp-on or clamp-around type, which will provide benefits of non-fouling operation and ease of installation. TFXP transit time flow meters utilize two transducers that function as both ultrasonic transmitters and receivers. See Figure 1.4.
PART 1 - INTRODUCTION temperature of 250 °F (121 °C). High temperature DTTH transducers can operate to a pipe surface temperature of 350 °F (177 °C). The DTTS small pipe transducers can be used to a pipe surface temperature of 185 °F (85 °C) and the DTTC high temperature small pipe transducers are rated for 250 °F (121 °C). User Safety The TFXP employs modular construction and provides electrical safety for the operator. The display face contains voltages no greater than 10 VDC.
PART 1 - SPECIFICATIONS TRANSMITTER Power Requirements Internal 12 V lead-acid Gel Cell battery provides 24 hrs of continuous operation @ 20 °C. Charging: Wall mount power converter. 115 or 230 VAC 50/60 Hz ±15% VA max; 12-15 VDC @ 2.5 VA max Velocity Range -40 to +40 FPS (-12 to +12 MPS) Inputs/Outputs All output modules are optically isolated from earth and system grounds. One module and one data logger may be installed.
PART 1 - TFXP TRANSMITTER CONNECTIONS 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.
PART 1 - TFXP TRANSMITTER CONNECTIONS Electrical Connections It is highly recommended that the internal battery in the TFXP be fully charged before using the meter for the first time. Details covering this procedure are located on page 1.1 of this manual. 1. The connectors located on the side of the TFXP consist of three 1/4-turn BNC-type and one 5.5 mm power plug.
PART 1 - TFXP TRANSMITTER CONNECTIONS Battery Charging and External Power Sources The 12 volt DC power converter and 12 volt auto-style power cord connect to the socket connection located on the side of the enclosure. See Figure 1.5 on page 1.11. A fully charged battery will provide up to 24 hours of continuous operation before recharging will be necessary. When the battery level has decreased to a point where recharging is required, the LOW BATTERY indicator will brightly illuminate on the front panel.
PART 1 - TFXP TRANSMITTER CONNECTIONS NOTE: The TFXP will automatically enter a low power consumption mode approximately 1-1/2 minutes after the LOW BATTERY indicator illuminates. This circuit prevents excessive discharge of the internal battery. • If the TFXP is stored for prolonged periods of time, monthly charging is recommended. • If the TFXP is stored for prolonged periods of time, store at a temperature below 70 ºF (21 ºC).
PART 1 - TFXP TRANSMITTER CONNECTIONS Standard 4-20 mA Output The standard 4-20 mA output may be replaced with one of the following five ISO-MODs: dual-relay, rate pulse, RS232C, RS485 and heat flow (RTD). TFXP supports one ISO-MOD input/output module in addition to the optional data logger. All modules are field configurable by utilizing the keyboard or ULTRALINK™ interface. Field wiring connections to ISO-MODs are quick and easy using pluggable terminals.
PART 1 - TFXP TRANSMITTER CONNECTIONS Optional Data Logger A 200,000-point Data Logger* is located within the weather-tight pocket on the faceplate of the flow meter. See Figure 1.7. Loosen the three thumbscrews located in the corners of the pocket cover and rotate the cover to expose the Data Logger Module. The logger stores time-stamped, high resolution (16-bit) data at user selected intervals ranging from 1 to 30,000 (8.33 hours) seconds.

PART 2 - TRANSDUCER & RTD INSTALLATION General The transducers that are utilized by the TFXP contain piezoelectric crystals for transmitting and receiving ultrasonic signals through walls of liquid piping systems. DTTN and DTTH transducers are relatively simple and straightforward to install, but spacing and alignment of the transducers is critical to the system's accuracy and performance. Extra care should be taken to ensure that these instructions are carefully executed.
PART 2 - TRANSDUCER & RTD INSTALLATION 1. Mounting Location The first step in the installation process is the selection of an optimum location for the flow measurement to be made. For this to be done effectively, a basic knowledge of the piping system and its plumbing are required. An optimum location is defined as: Rev. 5/09 • A piping system that is completely full of liquid when measurements are being taken.
PART 2 - TRANSDUCER & RTD INSTALLATION Table 2.1 1 — Piping Configuration and Transducer Positioning 1 The TFXP system will provide repeatable measurements on piping systems that do not meet these requirements, but the accuracy of these readings may be influenced to various degrees. Rev. 5/09 - 2.
PART 2 - TRANSDUCER & RTD INSTALLATION 2. Transducer Spacing TFX transit time flow meters are sold with four different transducer types: DTTN, DTTH, DTTS and DTTC. Meters that utilize DTTN or DTTH transducer sets consist of two separate sensors that function as both ultrasonic transmitters and receivers. DTTS and DTTC transducers integrate both the transmitter and receiver into one assembly that fixes the separation of the piezoelectric crystals.

Table 2.
PART 2 - TRANSDUCER & RTD INSTALLATION Important! Enter all of the data on this list, save the data and reset the TFX before mounting transducers The following information is required before programming the instrument. NOTE: Much of the data relating to material sound speed, viscosity and specific gravity is preprogrammed into the TFX flow meter. This data only needs to be modified if it is known that a particular liquid’s data varies from the reference value.
PART 2 - TRANSDUCER & RTD INSTALLATION 3. Transducer Mounting After selecting an optimal mounting location (Step 1) and successfully determining the proper transducer spacing (Step 2) the transducers may now be mounted onto the pipe. Pipe Preparation Before the transducers are mounted onto the pipe surface, an area slightly larger than the flat surface of each transducer must be cleaned of all rust, scale and moisture.
PART 2 - TRANSDUCER & RTD INSTALLATION The spacing between the transducers is measured between the two spacing marks on the sides of the transducers. These marks are approximately 3/4 inch back from the nose of the transducer. See Figure 2.3. DTTS and DTTC transducers should be mounted with the cable exiting within ±45 degrees of the side of a horizontal pipe. See Figure 2.2 on page 2.8. On vertical pipes the orientation is not critical. Figure 2.
PART 2 - TRANSDUCER & RTD INSTALLATION Transducer Positioning 2. Place the upstream transducer in position and secure with a mounting strap. Straps should be placed in the arched groove on the end of the transducer. A screw is provided to help hold the transducer onto the strap. Verify that the transducer is true to the pipe — adjust as necessary. Tighten the transducer strap securely. 3. Place the downstream transducer on the pipe at the calculated transducer spacing. See Figure 2.5.
PART 2 - TRANSDUCER & RTD INSTALLATION 4. If after adjustment of the transducers the signal strength does not rise to above 5 percent, then an alternate transducer mounting method should be selected. If the mounting method was W-Mount, then reconfigure the TFX for V-Mount, reset the TFX, move the downstream transducer to the new location and repeat Step 3 on page 2.10. 5. Certain pipe and liquid characteristics may cause signal strength to rise to greater than 195 percent.
PART 2 - TRANSDUCER & RTD INSTALLATION DTTH Transducers for High Temperature DTTH High Temperature Transducers Mounting of high temperature transducers is similar to standard DTTN transducers. High temperature installations require acoustic couplant that is rated not to “flow” at the temperature that will be present on the pipe surface. Installation consists of the following steps: 1. Apply a thin coating of high temperature acoustic couplant to the entire surface of the transducer face.
PART 2 - TRANSDUCER & RTD INSTALLATION 2. On horizontal pipes, mount the transducer in an orientation so that the cable exits at ±45° 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 is not critical. See Figure 2.2 on page 2.8. 3. Tighten the wing nuts or “U” bolts so that the grease begins to flow out from the edges of the transducer and from the gap between the transducer halves. Do not over tighten. 4.
PART 2 - TRANSDUCER & RTD INSTALLATION Figure 2.10 — Bisecting the Pipe Circumference 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 2.2 on page 2.8 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.
PART 2 - TRANSDUCER & RTD INSTALLATION 5. For DTTN transducers, place a single bead of couplant, approximately 1/2 inch (12 mm) thick, on the flat face of the transducer. See Figure 2.4 on page 2.9. Generally, a siliconebased grease is used as an acoustic couplant, but any greaselike substance that is rated to not “flow” at the temperature that the pipe may operate at will be acceptable. 6. Place the upstream transducer in position and secure with a stainless steel strap or other.
PART 2 - TRANSDUCER & RTD INSTALLATION Figure 2.11 — Z-Mount Transducer Placement Mounting Track Installation Rev. 5/09 D010-2102-010 Mounting Track Installation 1. The D010-2102-010 transducer mounting track is used for pipes that have outside diameters between 2 and 10 inches (50-250 mm). If the pipe is outside of that range, select a standard V-Mount or Z-Mount mounting method. 2. Install the single mounting rail on the side of the pipe with the stainless steel bands provided.
PART 2 - TRANSDUCER & RTD INSTALLATION Figure 2.12 — D010-2102-010 Mounting Track Installation Rev. 5/09 6. Secure with the thumb screw. Ensure that the screw rests in the counter bore on the top of the transducer. (Excessive pressure is not required. Apply just enough pressure so that the couplant fills the gap between the pipe and transducer.) 7. Place the second transducer in between the mounting rails near the dimension derived in the Transducer Spacing section.
PART 2 - TRANSDUCER & RTD INSTALLATION 4. RTD INSTALLATION For typical installations, the length of RTD wire should equal the length of the flow transducer cable. Ensure that the length of wire included with the RTDs is adequate to reach from the supply and return pipes to the location of the TFX transmitter. If the length of wire is insufficient, wire can be added on but a small temperature offset will result.
PART 2 - TRANSDUCER & RTD INSTALLATION Figure 2.13 — Surface Mount RTD Installation Insertion RTD Installation Insertion RTD Installation Insertion RTDs are typically installed through 1/4" compression fittings and isolation ball valves. 1. It is recommended that insertion RTDs be mounted downstream of the flow measurement transducers to avoid causing flow instability in the flow measurement region. 2. Insert the RTD into the flow stream so that a minimum of 0.25" of the probe tip extends into the pipe.

PART 3 - STARTUP AND CONFIGURATION Before Starting the Instrument NOTE: The TFX 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 Sonotemp® silicone grease was utilized as a couplant, a curing time is not required. However, if Dow 732 or another permanent RTV was used, the adhesive must fully cure before power is applied to the instrument.
PART 3 - KEYPAD CONFIGURATION General After installation of the transducers and connection of appropriate cabling to the TFX, keypad configuration of the instrument can be performed. All entries are saved in non-volatile FLASH memory and will be retained in the event of power loss. The TFX can be configured through the keypad interface or by using the ULTRALINK™ Windows® compatible software utility. (See Part 4 of this manual for software details.

PART 3 - KEYPAD CONFIGURATION 4. OUTPUT 2 MENU The second I/O bay is internal to the TFXP and can perform a number of different functions depending on the ISO Module installed. The following is a list of the current options and their menu designations. OUT2 MEN -- OUTPUT #2 MENU (Choice) 1. 2. 3. 4. 5. 6.
PART 3 - KEYPAD CONFIGURATION Figure 3.8 — 4-20 mA Output Wiring The 4-20 mA output can be configured to source current (internally powered) or sink current (externally powered). The choice of sink or source is configured at the factory to source current unless otherwise instructed at the time the TFX is ordered. The 4-20 mA output module interfaces with virtually all recording and logging systems by transmitting an analog current that is proportional to system flow rate.
PART 3 - KEYPAD CONFIGURATION External Power Configuration (Current Sink): If the 4-20 mA output module was ordered from the factory for external power the 4-20 mA module requires power from an external DC power supply. The voltage of the external power source must be sufficient to power the module and drive the loop load.
PART 3 - KEYPAD CONFIGURATION Example 1: To span the 4-20 mA output from -100 GPM to +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 Example 2: To span the 4-20 mA output from 0 GPM to +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 The 4-20 mA ISO-MOD is factory calibrated and should not require adjustment unless it is replaced.
PART 3 - KEYPAD CONFIGURATION NOTE: The CAL 4MA and CAL 20MA entries should not be used in an attempt to set the 4-20 mA range. Utilize the FL 4MA and FL 20MA, detailed on page 3.26, for this purpose. Procedure: 1. Disconnect any wires presently connected to the spring clips on the end of the 4-20 mA output cable. Connect the ammeter in series with the spring clips on the end of the 4-20 mA output cable. NOTE: Be sure to connect the multimeter test leads for current measurement.
PART 3 - KEYPAD CONFIGURATION 4-20 mA Test 4-20 TST -- 4-20mA Output Test Allows a simulated value to be output from the 4-20 mA module. By incrementing this value, the 4-20 mA output will transmit the indicated current value. NOTE: This test is only available when the 4-20 mA module is set up to source current.
PART 3 - KEYPAD CONFIGURATION Example 2: To span the 0 to 2.5k Hz output from 0 GPM to +100 GPM, with 1.25k Hz being 50 GPM, set the FL 0H and FL 25KH inputs as follows: FL 0H = 0.0 FL 25KH = 100.0 K-Factor Programming K-Factor Programming If the device receiving the pulse output is capable of K-factor scaling, it is possible to use the rate pulse output in a totalizing function. See K-Factors Explained in the Appendix. Figure 3.11 — Rate Pulse Output Wiring Rev. 5/09 -3.
PART 3 - KEYPAD CONFIGURATION ISO-MOD: Dual Relay Module (Optional) RELAY -- Dual Relay (Choices and Values) RELAY 1 AND RELAY 2 1. None 2. Totalizer a. Totalizer Multiplier 3. Flow a. On Setting b. Off Setting 4. Signal Strength a. On Setting b. Off Setting 5. Errors (NONE) (TOTALIZE) (TOT MULT) (FLOW) (ON) (OFF) (SIG STR) (ON) (OFF) (ERRORS) Two independent SPDT (single-pole, double-throw) Form C relays are contained in this module.
PART 3 - KEYPAD CONFIGURATION Batch/Totalize Mode Totalize mode configures the relay(s) to output a 50 mSec pulse (contact changeover) each time the display totalizer increments – divided by the Total Mult. The Total Mult value must be a whole, positive, numeric value. Example 1: If the Totalizer Exponent is set to E0 (×1) and the Totalizer Multiplier is set to 1, then the relay will pulse each time the totalizer increments one count, or each single, whole measurement unit totalized.
PART 3 - KEYPAD CONFIGURATION Signal Strength Alarm The Sig Str alarm will provide an indication that the flow meter signals between the transducers have fallen to a point where flow measurements may not be possible. It can also be used to indicate that the pipe has emptied.

PART 4 - SOFTWARE UTILITIES Important Notice! The TFXP flow meter can be used with two software utilities, ULTRALINK™ and Data Logger. The ULTRALINK™ utility is used for configuration, calibration and communication with the TFXP flow meter. The Data Logger utility is used for uploading and translating data accumulated in the data logger module located in the pocket on the front faceplate of the flow meter.
PART 4 - SOFTWARE UTILITIES Initialization Connect the infrared communications adapter to a PC communication port and point the communicator at the TFXP infrared window located in the lower right-hand corner of the keypad. If meter is ordered with either ISO-MOD RS232 or ISOMOD RS485 options, connect the PC communications cable directly to the DB-9 connection located on the side of the TFXP meter. Click on the Communications button in the menu bar. Next click on Initialize.
PART 4 - SOFTWARE UTILITIES Figure 4.2 — “Data Display” Screen Pipe and Liquid Configuration The first screen that appears after clicking the Configuration button is the BASIC tab. See Figure 4.3 on page 4.5. Basic Tab General Units allows selection of either English (U.S.) or Metric units of measure. If measurements of the pipe are to be entered in inches, select English. If measurements are to be entered in millimeters, select Metric.
PART 4 - SOFTWARE UTILITIES Transducer Mount selects the orientation of the transducers on the piping system. See Part 2 of this manual and Table 2.2 on page 2.5 for detailed information regarding mounting modes for particular pipe and liquid characteristics.

Damping values are decreased to allow the flow meter to react faster to changing flow rates.
PART 4 - SOFTWARE UTILITIES 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 unidirectional system this value is typically set to zero to indicate zero flow while in an error condition. In a bi-directional system, the percentage can be set such that zero is displayed in an error condition.
PART 4 - SOFTWARE UTILITIES Time Domain Filter adjusts the number of raw data sets (the wave forms viewed on the ULTRALINK™ Diagnostics Screen) that are averaged together. Increasing this value will provide greater damping of the data and slow the response time of the flow meter. This filter is not adaptive – it is operational to the value set at all times. Low Signal Cutoff is a duplicate entry from Flow tab. Adjusting this value adjusts the value on the Flow tab.
PART 4 - SOFTWARE UTILITIES 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 entry is entered in picoseconds and is differential time. If very small fluid velocities are to be measured, increasing the Flow Filter MinHysteresis value can increase reading stability.
PART 4 - SOFTWARE UTILITIES Output Configuration Output Tab The entries made in the Output tab establish input and output calibration and ranges for ISO-MOD modules installed in the TFX flow meter. If a module was ordered from and installed at the factory, then the Output tab will contain information and configuration for that module. If a module has been changed from the factory setting, a configuration error will result.
PART 4 - SOFTWARE UTILITIES Calibration/Test is used to adjust the factory calibration span of the 4-20 mA output and to test the output. The 4-20 mA output is factory calibrated and should not require adjustment in the field. If the module is replaced or if recalibration is required, the following procedure is used to calibrate the span of the module: 1. Connect a milliamp meter serially within the 4-20 mA module output. 2. Check the Calibration/Test box. 3. Select the 4 mA Calibration box. 4.

HEAT FLOW ADDENDUM General The TFX flow meter with the optional RTD (heat flow) Module installed 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 FLOW ADDENDUM Installation Installation 1. Follow the instructions outlined in the standard TFX manual for proper installation of the ultrasonic transducers. After installation, verify that the signal strength is sufficient for stable flow readings and, if possible, perform a Zero flow calibration on the pipe. Please note that all readings require a full pipe of liquid. 2. Select areas on the inlet and outlet pipes where the RTDs will be mounted.
HEAT FLOW ADDENDUM 5. Route a cable from the electrical junction box back to the TFX flow meter. Connect the RTDs as illustrated in Figure A.2. Note that the SNS1 and DRV1 wires originate from the same location on the RTD. Figure A.2 — RTD Connection Programming Transmitter Programming 1. The RTDs included with the TFX heat flow option have been factory calibrated and are marked with an identification as to which terminal, #1 or #2, the RTD has been calibrated.
HEATFLOW FLOWADDENDUM DDENDUM HEAT UNIT list. Select the appropriate RATE INTERVAL from the list (seconds, minutes, hours, days). Be aware that the instrument can only display values as large as 99,999,999. 4. Select an appropriate TOTALIZER UNIT from the list; BTUs, MBTU, MMBTU, or TON . 5. From the main display, three values can be accessed that may aid in troubleshooting the heat flow instrument.
HEAT FLOW ADDENDUM Accuracy Accuracy The accuracy of BTU measurements relies on two separate measurements – mass flow and difference temperature. The BTU meter can measure volumetric flow to within about 1% of reading accuracy. For example if the liquid is chilled water in the range of 40-60 °F, the influences on mass flow accuracy within this temperature range, with a volumetric flow meter are on the order of 0.073% potential error.

K-Factors Explained The K-factor (with regards to flow) is the number of pulses that must be accumulated to equal a particular volume of fluid. You can think each pulse as representing a small fraction of the totalizing unit. An example might be a K-factor of 1000 (pulses per gallon). This means that if you were counting pulses, when the count total reached 1000, you would have accumulated 1 Gallon of liquid. Using the same reasoning each individual pulse represents an accumulation of 1/1000 of a gallon.
Example 2 Known values are: Full Scale Flow Rate Full Scale Output Frequency = 85 GPM = 650 Hz 650 Hz x 60 sec = 39,000 pulses per min K-factor = 39,000 pulses per min = 458.82 pulses per gallon 85 GPM The calculation is a little more complex if velocity is used because you first must convert the velocity into a volumetric flow rate to be able to compute a K-factor.
4) What is the flow rate in GPM at 4.3 ft/sec. 0.384 gallons x 4.3 FPS x 60 sec (1min) = 99.1 GPM Now that the volumetric flow rate is know all that is needed is an output frequency to determine the K-factor. Known values are: Frequency Flow Rate = = 700 Hz (By measurement) 99.1 GPM (By calculation) 1) 700 Hz x 60 sec = 42,000 pulses per min 2) K-factor = 42,000 pulses per min = 423.9 pulses per gallon 99.

TFX Communications Using UltraLink The current implementation of the UltraLink software utility was originally developed for Windows 95, Windows 98, and Windows 2000 using a standard RS-232 port. These operating systems left the choice of serial ports much more in the users hands. The physical connection was also the age-old DB-9 serial connections found on all computers of the time. With the introduction of Windows XP using USB serial ports inputs connections became a little more troublesome.
This converter is required regardless of the operating system or the type of port on the computer. The next step up is the infrared connections used on TFXD, PE1, TFXP, HTTP, PE3, TFXM, PE2 transit time meters and MFX series mag probes. Do not confuse this with the general propose infrared ports built into many computers, calculators, and printers. To make a connection to UltraLink a dedicated IR device is required.
USB (Universal Serial Buss) Ports USB ports also come in a variety of physical configurations. The two most common are USB A and USB B. In most computers the USB A configuration is the most default. The first problem is the need to convert the RS-232 output to a USB format. Complicating issues even more is that there are two major flavors of USB implementations depending on the age of the computer.
The device manager window should look something like this. Communicating with UltraLink Once the com port properties are known the next step is to configure UltraLink to talk on the correct port with the correct device. Open UltraLink and from the main data display screen click on the Communications drop down in the menu bar. When the communications drop down opens choose Initialize. The initialize window has two fields to make choices from. The first choice is for the com port to be used.
The figure on the left shows a typical communications setup for a TFXL, HTTF, or PTTF. The TFXL, HTTF, and PTTF all use a standard RS232 com port type. The TFXD, PE1, TFXP, HTTP, PE3, TFXM, and PE2 primary communications link uses the IrDA Actisis 220L infrared communications adapter. A typical com port setup for this device would look similar to this. Once the com port and com port type have been entered press OK to finalize the initialization.
Verifying Communications There are several possible combinations of indicators that signal communications status. In the lower right hand corner of the Data Display screen there is a Comm box that can take on one of three values. A green OK means that the physical connection to the serial port is intact. A red Error indicates some kind of communications problem. A red Offline is saying that the connection between the computer and UltraLink has been turned off.
Digital Communications Protocol for TFX Flow Meters Host protocol A digital communications protocol is utilized. Each message is guarded with the standard CRC-16 error detection (C source code is included) The host protocol is a master-slave type protocol with the flowmeter being the slave. The messages have the following format: … A unit may be assigned an address that responds to (valid addresses are 1-7E). All devices respond to address 7F (ie.
