December 2003 Chapter 1 Features and Capabilities The TransPort™ Model PT868 is a transit-time flowmeter which combines all the features of a full-size flowmeter with the advantages of a portable instrument. This section describes the TransPort features and general system, and explains the theory of operation. Overview The TransPort measures acoustically conductive single-phase fluids, which may have a second phase present.
December 2003 The TransPort has the ability to store site data for up to 20 sites into files which can be accessed at a later time. A menu-driven user program asks you all the necessary setup questions for a particular site. Once you complete answering the necessary questions, you simply save the information into a file. The TransPort stores these files and other data in non-volatile memory, which retains the information even if power is off.
December 2003 System Description The TransPort is one part of the flowmeter system. The flowmeter system consists of two essential subsystems: the flowcell and the electronics package (the TransPort). The Flowcell The flowcell is that part of the system that uses ultrasonic pulses to interrogate the flow. It consists of the flowcell pipe and the transducers. A.
December 2003 Electronics Package The TransPort consists of circuits that generate, receive, and measure the travel time of the ultrasonic pulses. It also contains a microcomputer that controls operation and calculates flow measurement parameters. Specific circuits function as follows: A.TRANSMIT SIGNAL GENERATOR - The transmit signal generator, under control of the microcomputer and timing circuit, synthesizes the signal that drives the transmitter. B.
December 2003 Theory of Operation The TransPort is a transit-time ultrasonic flowmeter. When ultrasonic pulses are transmitted through a moving liquid, the pulses that travel in the same direction as the fluid flow (downstream), travel slightly faster than the pulses that travel against the flow (upstream). The TransPort uses various digital signal processing techniques, including cross-correlation, to determine transit times and then uses the transit times to calculate flow velocity.
December 2003 Chapter 2 Initial Setup Before making measurements, you must prepare the TransPort for operation.

December 2003 Using the Graph Format (cont.) Note: Since the time displayed on the status line will only show whole minutes and not seconds, if you selected a time increment of less than 1 minute, the time will not change every time you press the cursor key. For example, if you chose a 5-second increment, you will have to press the cursor key 12 times before the time changes. Use the [←] [→] keys to access the other feature key options for viewing the data in the graph format.
December 2003 Log Format The Log Format enables you to display logged data graphically or numerically. The TransPort displays all of the data in the log file; however, because of the limited space on the screen, the TransPort cannot display all data on the screen simultaneously. Therefore, you must use the feature key options to view the remaining data. Note: Before viewing a log, you must create a log. This process is described in Chapter 6, Logging Data.
December 2003 Using the Numeric Log Format Figure 4-5 below shows an example of a log displayed in the numeric format. The screen displays the measurement values numerically, including the time and date the measurement was taken. Each set of measurement values is called a record. The TransPort is capable of storing up to 120 pages of records. Each page consists of 120 records. The last line of the screen displays any error messages.

December 2003 Displaying the Signal (cont.) When displaying the signal, the TransPort can display the following : • Upstream signal (Sup) • Downstream signal (Sdown) • Upstream Correlation (Cup) • Downstream Correlation (Cdown) • Cross-correlation (CC) You can toggle between the above displays using the [1] and [2] keys. [1] toggles up, and [2] toggles down. Additionally, [4] vertically enlarges the signal, and [5] reverts it to the original size.
December 2003 Chapter 6 Logging Data A powerful and flexible feature of the TransPort is data logging. The TransPort enables you to choose from up to six sets of parameters to log. You can also select the start time and date, end time and date, and time interval. Logs can run one at a time or simultaneously. Error and circular logs are also available. Logged data is internally stored in battery backed up memory. The TransPort stores logged data in pages, allocating 120 pages of memory for data logging.
December 2003 Once you make your data logging selections, the TransPort enables you to view the amount of memory left. You may also stop logging or view logged data while or after data is logged as described in Chapter 4, Displaying Data. This section describes: • How to enter the Log Menu. • How to setup the data logger. • How to view the data logger memory. • How to stop logging.
December 2003 Entering the Log Menu To access the Log Menu, press the [LOG] key. The screen should appear similar to that shown in Figure 6-1 below. The indicator box shows you are at the beginning of the Log Menu. Refer to Appendix D, Menu Maps, Figure D-3 for a flow diagram of the LOG Menu.

December 2003 Entering Data Log Parameters (cont.) Once you have completed entering the log parameters, the TransPort returns you to the beginning of the Log Menu. You should now check if there is enough memory available to store the parameters you desire to log as described in the following section. To exit, press the [EXIT] key. The “*” in the indicator box indicates the TransPort is currently logging.
December 2003 Checking the Data Logger Memory Although the TransPort has 120 pages for logger memory, it is a good practice to check the availability of logger memory after setting up a log to see if the amount of data you want to log exceeds the amount of available memory. To check the memory do the following: 1. If you have not, access the Log Menu by pressing the [LOG] key. 2. Press [F2] to select memory.
December 2003 Checking the Data Logger Memory (cont.) Use the following formula to figure out how many pages a log will use: length of log × no. of readings/unit time = no. of records then, no. of records ÷ 120 = no. of pages For example, if you select a log to run for 24 hours with a time increment of 1 minute this log will use 12 pages of memory because: 24 × 60 = 1440 records 1440 ÷ 120 = 12 pages To Stop Logging To stop logging: 1. Press the [LOG] key to access the Log Menu. 2.
December 2003 Error Logging To compile a log of up to three specified error parameters, follow this procedure: 1. Press the [LOG] key to access the Log Menu. 2. Press [F4] to select “ERROR.” 3.

If you have one or more logs left, the TransPort returns to the beginning of the Clear Log option. You may now clear another log or press the [EXIT] key to return to making measurements.
December 2003 Chapter 8 Calibrating Analog Outputs and Inputs To calibrate the analog outputs and inputs, or use the optional ultrasonic thickness gage, you must enter the Calibration Menu by pressing the [CAL] key. When you enter the Calibration Menu the screen appears similar to that in Figure 8-1 below. The Calibration Menu has the three following options (refer to Appendix D, Menu Maps, Figure D-6 for a flow diagram of the Calibration Menu): • A/OUT - enables you to calibrate the analog outputs.
December 2003 Analog Outputs To calibrate the TransPort 4-20 or 0-20 mA output, you need to connect a multimeter or ammeter to the analog output connector shown in Figure 8-2 below (refer to page 2-3 for more information for connecting the analog output). XDCR UP- DOWN- STREAM STREAM PWR 1 ANALOG I/O RS232 1 7 2 3 2 6 FLOW 1 PWR RS232 1. 12VDC-28VDC 6W MAX. 2. RETURN 1. GND(BROWN) 2. TX(RED) 3. RX(ORANGE) 4. DTR(YELLOW) 5. No Connection . (GREEN) 4 6 5 8 ANALOG I/O 1.
December 2003 Analog Outputs (cont.) 4. The screen will display four choices: 4 mA, 20 mA, TEST and EXIT. Press [F1] to select “4 mA”. You must calibrate the low end to 4 mA regardless of the type of output you are using. (If you are using a 0-20 mA output, the TransPort extrapolates the 0 mA point from the 4 mA calibration.) 5. Check the mA reading on the multimeter or ammeter. It should read close to 4 mA. If it does not, use one of the following keys to adjust the reading to 4 mA.
December 2003 Testing the Analog Output Linearity If you select Test in Step 4, the PT868 automatically sets the output to 50%. The resulting mA reading should read close to 12 mA on a 4-20 mA scale (10 mA on a 0-20 mA scale). 1. At the % FULL SCALE prompt, enter a value from 0 to 100 % and press [ENT]. 2. Check the resulting mA reading again. If the reading is off, go back and recalibrate the analog output zero and full scale.
December 2003 Analog Inputs The TransPort enables you to calibrate the analog inputs using a temperature range or a 4 to 20-mA current. To calibrate the temperature input, you need to connect a low and high temperature reference (or calibrated current source) to the temperature input connector shown in Figure 8-3 below. XDCR UP- DOWN- STREAM STREAM PWR 1 ANALOG I/O RS232 1 7 2 3 2 6 FLOW 1 PWR RS232 1. 12VDC-28VDC 6W MAX. 2. RETURN 1. GND(BROWN) 2. TX(RED) 3. RX(ORANGE) 4. DTR(YELLOW) 5.
December 2003 Low and High Calibration Use the following steps to calibrate the inputs: Calibrating the Low Input 1. Connect the low temperature reference (or current source) to the temperature input (see Figure 8-3 on the previous page). 2. If you have not already, enter the Calibration Menu by pressing the [CAL] key. 3. Press [F2] to select “A/IN.” 4. The prompt will ask you to select Input 1 or Input 2. Press [F1] to select Input 1 or [F2] to select Input 2. 5.
December 2003 Low and High Calibration (cont.) You have completed calibrating the analog inputs. You may now do one of the following: • If you are finished calibrating inputs/outputs, press [EXIT] twice and the TransPort begins taking measurements. • If you want to calibrate the analog output, press [EXIT] and refer to page 8-2 for instructions. To reconnect the analog outputs and inputs, refer to Chapter 2, Initial Setup.
December 2003 Chapter 9 Using the Ultrasonic Thickness Gage The TransPort can measure thickness when equipped with the optional ultrasonic thickness transducer (supplied separately). The ultrasonic thickness transducer connects to the transducer connectors. The internal thickness gage not only measures the thickness of a pipe, but can also measure the sound speed of a substance if the thickness is known. The Thickness Gage is factory calibrated and programmed.
December 2003 Connecting the Ultrasonic Thickness Transducer Plug the ultrasonic thickness transducer into the transducer connectors located on the top of the TransPort (see Figure 9-1). Note that the transducer cable plug must be oriented with the center pin down. Thickness Transducer PWR 1 ANALOG I/O RS232 XDCR 1 7 2 3 2 6 4 6 5 8 1 Figure 9-1: Ultrasonic Thickness Transducer Connections !WARNING! When unplugging the transducer, pull on the molded plug only. Do not pull on the cable.
December 2003 Measuring Pipe Thickness The TransPort displays thickness measurements numerically. You may also view the signal and thickness measurements graphically. The graph format displays the signal for as long as you hold the transducer to the pipe. The graph format also has a special feature that enables you to find the signal zero crossing used to calculate the thickness. Use the following sections to make thickness measurements. Making Measurements To measure the pipe wall thickness: 1.
December 2003 Making Measurements (cont.) 3. Use the [←] [→] keys to view all the selections for pipe material. Use the appropriate feature key to make a selection. If your pipe material is not listed, choose the “OTHER” option and enter the longitudinal sound speed of the pipe material. Sound Speeds and Pipe Size Data contains a list of common pipe materials and the corresponding longitudinal sound speeds.
December 2003 Measuring the Sound Speed The Thickness Gage is capable of measuring the sound speed of a material if the thickness of the material is known (at a flange, for example). Use the steps below to measure the sound speed: 1. Press the [CAL] key to enter the Calibration Menu, and then press [F3] to select “WALL”. The screen should appear similar to that shown in Figure 9-4. 2. Press [F3] to select “SNDSP.
December 2003 Graphically Displaying Thickness Transducer Signal To troubleshoot the unit or verify thickness readings, the TransPort enables you to view the thickness transducer signal. To display the thickness gage signal, press the [F1] key to select “GRAPH.” Note: If you are not in the Calibration Menu, press the following keys: [CAL]; [F3] to select “WALL”; [F1] to select “GRAPH.” Figure 9-5 below shows an example of thickness signal.
December 2003 Graphically Displaying Thickness Transducer Signal (cont.) The TransPort displays 120 samples per page. Since there is a limited amount of space to display readings, use the feature key options to view the remaining data. The following options are available (use the [←] [→] keys to view all the options): • [] keys - to move one sample at a time. • [] keys - to pan an entire page. Each page is 3.75 msec.
December 2003 Calibrating the Thickness Gage The ultrasonic thickness gage is factory calibrated; therefore, you only need to perform calibration if you receive new transducers or have a reason to doubt the accuracy of the readings. To calibrate you will need: • a test block, which is shipped with the thickness transducer (or test block of known sound speed and length) • ultrasonic couplant To calibrate the thickness gage, you must enter the Calibration Menu and then enter the appropriate data.
December 2003 Calibrating the Thickness Gage (cont.) 3. The TransPort displays one of the test block lengths. This is the end you should use to calibrate first. Apply couplant to the appropriate end of the test block and place the thickness transducer on the block. The transducer face should be flat against the surface of the test block. 4. The screen should display approximately the correct thickness of the test block. Press the [F1] key to select “CAL.” The TransPort locks in the calibration. 5.
December 2003 Programming the Ultrasonic Thickness Gage Once you access the Thickness Gage option, the TransPort converts from an ultrasonic flowmeter to an ultrasonic thickness gage. The thickness gage has a Program Menu that enables you to view or change the following parameters: • Low Signal Threshold • Detection Threshold • Transducer Delay • Gain Level • Signal Inversion The thickness gage settings are entered at the factory. You should not change them unless instructed by the factory.
December 2003 Programming the Ultrasonic Thickness Gage (cont.) PROGRAM Start LOW SIGNAL THRESHOLD 45 Figure 9-6: Thickness Gage Program Screen Low Signal Threshold This parameter sets the signal strength alarm. If the signal strength falls below this value, a “Low Signal” message appears on the screen. This number should be set to 45 unless otherwise instructed by the factory. To change this number: 1. Use the numeric keys to enter the new number. 2. Press [ENT].
December 2003 Transducer Delay This number represents the time the ultrasonic signal takes to travel from the TransPort to the pipe material surface. This number should be set to 7.0 microseconds unless otherwise instructed by the factory. To change this number: 1. Use the numeric keys to enter the new number. 2. Press [ENT]. The TransPort proceeds to the next prompt.
December 2003 Signal Inversion This prompt enables you to invert the thickness transducer signal. Signal inversion may be required if your thickness readings are showing excessive jitter or for certain unusual combinations of pipe and fluid or pipe and lining. Consult the factory before measuring the thickness of lined pipes.
December 2003 Chapter 10 Diagnostics and Troubleshooting The TransPort is a reliable instrument that is easy to maintain. It will provide accurate flow measurement readings as long as it is operated as described in this manual. If problems do arise with the electronics, transducers or the flowcell, the TransPort displays an error message specifying the possible problem. The TransPort also has a set of diagnostic parameters to help you find and remedy the problem.
December 2003 Error Code Messages Error Code messages appear on the screen while you are displaying measurements. Error Codes do not appear when you are displaying measurements in graph form, or when displaying logged data. The Error Code messages are only general descriptions of the possible problems. Use Table 10-1 on the next page to isolate and remedy the problem. If you are unable to remedy the problem, contact GE Panametrics.
December 2003 Table 10-1: Error Messages Error Message Problem Possible Cause Action E0 No error. Displays briefly after the display of another error message None required. E1 Low Signal Poor ultrasonic signal strength. Broken cable. Flowcell problem. Transducer problem. Electronic failure. Check transducer cable. See Flowcell Problems on page 10-8 and Transducer Problems on page 10-12. Check programming and transducer spacing. Contact the factory if problem persists.
December 2003 Table 10-1: Error Messages (Continued) Error Message 10-4 Problem Possible Cause Action E4 Signal Quality If too high - electronic failure. If too low - flowcell, electrical problem. Check for source of electrical interference. Check electronics with a test flowcell. If unit still fails to operate, contact the factory E5 Amplitude Error Excessive particles or bubbles present in fluid. A lot of second phase present See Flowcell Problems on page 10-8.
December 2003 Displaying Diagnostic Parameters The TransPort provides a Diagnostic Menu to aid in troubleshooting in the event of flowcell, transducer, or electrical problems. Note: The TransPort must be displaying measurements in the Big or Dual Formats as discussed in Chapter 4, Displaying Data, on pages 4-2 and 4-3 to view diagnostic parameters. You can enter the Diagnostic Menu two ways: • Use the right arrow key until “DIAG” appears and then press [F4] to select, or • Press the [EXIT] key.
December 2003 Table 10-2: Diagnostic Parameters Diagnostic Parameter Displays Good Bad SS up Displays the signal strength for the upstream transducer. 50-80 <50 SS do Displays the signal strength for the downstream transducer. 50-80 <50 SNDSP Displays the measured sound speed of the fluid. Check the sound speed of fluid in Sound Speeds and Pipe Size Data. Tup Displays the upstream transit time of the ultrasonic signal in micro seconds.
December 2003 Table 10-2: Diagnostic Parameters (Continued) Diagnostic Parameter Displays Good Bad AMPup Displays the value for the amplitude discriminator of the upstream transducer. 20-28 less than 20 or greater than 28. AMPdn Displays the value for the amplitude discriminator of the downstream transducer. 20-28 fluctuations less than 20 or greater than 28 fluctuations P#up Displays signal peaks for the upstream transducer.
December 2003 Flowcell Problems Flowcell problems fall into two categories: fluid problems and pipe problems. Read the following sections carefully to determine if such problems exist. Fluid Problems Most fluid-related problems can be solved by proper design of the flowmeter installation and the proper choice of transducer frequency. Contact GE Panametrics if you cannot solve a fluidrelated problem. Certain fluid properties may prevent proper flow measurement.
December 2003 Fluid Problems (cont.) 4. THE FLUID SOUND SPEED MUST NOT VARY EXCESSIVELY. The TransPort will tolerate relatively wide, but slow, changes in fluid sound speed due to changes in fluid composition and temperature. However, if you are measuring a fluid that is considerably different from the fluid programmed into the TransPort, you may have to adjust the meter for the new fluid. Refer to Chapter 3, page 3-10, Entering Pipe Parameters.
December 2003 Pipe Problems Improper pipe conditions and/or flowcell installation can cause problems with measurement of the fluid flow. Check the items below if you suspect this class of problem. Contact GE Panametrics if you cannot solve pipe-related problems. 1. THE INSIDE OF THE PIPE OR FLOWCELL MUST BE RELATIVELY CLEAN. Excessive build up of scale, rust, or debris will interfere with flow measurement. Generally, a thin coating or a solid well-adhered buildup on the pipe wall will not cause problems.
December 2003 Pipe Problems (cont.) 4. THE PIPE SURFACES SHOULD BE SMOOTH (FOR CLAMP-ON). When using clamp-on transducers, both the inside and the outside of the pipe at the transducer locations must be smooth. If the pipe is extremely rough, the ultrasonic signal will be scattered by the rough surface, and will not be received by the flowmeter, preventing flow measurement. 5. THE PIPE MUST ALLOW ULTRASOUND TO PASS THROUGH (FOR CLAMP-ON).
December 2003 Transducer Problems Ultrasonic transducers are rugged. However, they are subject to physical damage due to mishandling and chemical attack. Clampon transducers are also subject to installation variables such as physical misalignment and faulty coupling to the pipe on which they are mounted. Because transducer problems are largely dependent on the type of transducer used, wetted or clamp-on, the following list of potential problems is grouped according to transducer type.
December 2003 Wetted Transducer Problems (cont.) 3. INTERNAL DAMAGE An ultrasonic transducer consists of a ceramic “crystal” bonded to the transducer case. The bond between the crystal and the case may be damaged by extreme mechanical shock and by temperature extremes. The crystal itself can also be damaged by the same conditions. The internal wiring can be corroded or shorted if contaminants enter the transducer housing. 4.
December 2003 Clamp-on Transducer Problems 1. POOR COUPLING TO PIPE Clamp-on transducers must be in intimate contact with the pipe. The pipe wall must be smooth and generally free of paint. The couplant material must fill voids between the transducer and the pipe, and must be firmly coupled or bonded to both the pipe and the transducer. The pipe and transducer must be clean and dry for permanent couplant, such as grease or epoxy, to adhere properly.
December 2003 Clamp-on Transducer Problems (cont.) 4. PHYSICAL DAMAGE Transducers may be physically damaged by dropping them onto a hard surface or striking them against another object. Usually the connector on the transducer is the part that is damaged, as it is the most fragile. Minor damage may be repaired by carefully bending the connector back into shape. If the connector cannot be repaired, replace the transducers.
December 2003 Clamp-on Transducer Problems (cont.) If the coupling or pipe wall are not the problem, try relocating the transducers using the following method. However, before beginning, make sure the transducers are not located on or near pipe welds or seams: • Move the upstream transducer about 1/2 inch (12.7 mm) closer to the downstream transducer. If this resolves the problem, you must modify the “S” dimension programmed into the TransPort by using the following steps: 1. Press [PROG] . 2.

December 2003 Appendix A Entering Special Transducer Pipe Parameters If you are using special transducers, the TransPort should be completely programmed when you receive your unit. However, in the unlikely event that data is lost, use this appendix to properly program pipe parameters. The series of prompts that appear in this menu depend on the type of special transducers you are using: wetted or clamp-on.
December 2003 PROGRAM Pipe parameters TRANSDUCER NUMBER 91 Figure A-1: Screen After Pressing PIPE Key 1. Entering the Transducer Number Enter the transducer number. Because you are using a special transducer, do the following: 1. Press [F1] to tell the TransPort you are using a special transducer. 2. Enter a number. The TransPort allows you to use more than one set of special transducers, therefore, assign a number from 91-99. 3. Press [ENT]. 2.
December 2003 Entering Parameters for Clamp-On Transducers If you are using Rayleigh or Shear wave clamp-on transducers, you will get the following prompts: • • • • • • • • • • • • • • • Frequency Tw (time delay) Wedge Angle Wedge Sound Speed Pipe Material Pipe Sound Speed Pipe O.D.
December 2003 Entering Parameters for Clamp-On Transducers (cont.) 4C. Entering the Time Delay Tw, the time delay, is actually the time the transducer signal spends travelling through the transducer and cable. This time must be taken into consideration since the TransPort calculates the flow rate by subtracting the time of the upstream and downstream signals. Therefore, the time delay must be subtracted out for an accurate measurement.
December 2003 Entering Parameters for Clamp-On Transducers (cont.) 7C. Entering the Pipe Material Enter the pipe material. Since clamp-on transducers send their ultrasonic signals through the pipe wall, the sound speed of the pipe material must be factored in to obtain an accurate flow measurement. Clamp-on transducers are applicable on a variety of pipe materials, only a few of which are among the options for this prompt.

December 2003 Entering Parameters for Clamp-On Transducers (cont.) 13C. Entering the Reynolds Correction Factor The Reynolds Correction Factor is a number based on the viscosity and flow rate of the fluid. Generally, it should only be enabled when using transducers mounted in a diametrical path (such as clamp-on or tilted diameter). If you enable the Reynolds Correction Factor, you will also need to enter the Kinematic Viscosity of the fluid (units are ft2/sec or m2/sec depending on the units selected).
December 2003 Entering Parameters for Clamp-On Transducers (cont.) 16C. Display of Transducer Spacing The next prompt shows the suggested spacing of the transducers calculated from the information entered. Use the Liquid Transducer Installation Guide as a guide to installing the transducers on the pipe with the spacing dimension (S) given here. Set the transducers to the spacing shown at this prompt.
December 2003 Entering Parameters for Wetted Transducers If you are using wetted transducers, you will see the following prompts: • Frequency • Tw (time delay) • Pipe OD (pipe outside diameter) • Pipe Wall • Path Length (P) • Axial Dimension (L) • Tracking Windows • Fluid Type • Reynolds Correction Factor • Calibration Factor 3W. Entering the Frequency Enter the transducer frequency.
December 2003 Entering Parameters for Wetted Transducers (cont.) 4W. Entering the Time Delay Tw, the time delay, is actually the time the transducer signal spends travelling through the transducer and cable. This time must be taken into consideration since the TransPort calculates the flow rate by subtracting the time of the upstream and downstream signals. Therefore, the time delay must be subtracted out for an accurate measurement. Use the numeric keys to enter the time delay (in microseconds).
December 2003 Entering Parameters for Wetted Transducers (cont.) 6W. Entering the Pipe Wall Thickness If you are not sure of the pipe wall thickness, Sound Speeds and Pipe Size Data contains some standard pipe sizes with their corresponding wall thicknesses. Also, the pipe wall thickness can be determined by using the optional internal ultrasonic thickness gage as described in Chapter 9, Using the Ultrasonic Thickness Gage. Use the numeric keys to enter the pipe wall thickness. Press [ENT]. 7W.
December 2003 Entering Parameters for Wetted Transducers (cont.) 8W. Enter the Axial Length (L) GE Panametrics has calculated the axial length (L) of the ultrasonic signal based on the transducer configuration for your particular application. Find the axial dimension on the flowcell or from other supplied documentation. 1. Press the appropriate feature key to select the desired units. 2. Use the numeric keys to enter the axial length. Press [ENT].

Then use the appropriate feature key to make a choice. Depending on the fluid type you choose, the TransPort may ask you for additional information such as fluid temperature or sound speed. 11W.
December 2003 Entering Parameters for Wetted Transducers (cont.) You have completed entering data into the PIPE option. You may at this time do one of the following: • Use the [↑] and [↓] arrow keys to verify or change data. • Continue to enter data in other menus as described in Chapter 3, Programming Site Data. • Press [EXIT] to exit the Program Menu and begin taking measurements. If you decide to exit, you must have already programmed the system parameters in order to make flow measurements.
December 2003 Appendix B Calculating P and L Dimensions If you are using wetted transducers, the TransPort requires that you enter the path length and the axial dimension. These dimensions are referred to as P and L. P is the transducer face to face distance and L is the axial projection of P in the flow stream. To determine L, physically measure the distance between the center of the transducer ports at the inside wall as shown in Figure B-1, if possible. If not, consult the factory.
December 2003 To determine P, you need the following: • the pipe inside diameter (ID) • the wall thickness (WT) • the installed pipe coupling length (CL) • the transducer face depth (FD) • the mounting angle (MA) Use Figure B-2 to properly measure the coupling length. Typically, the transducer face is positioned just outside the inside diameter (ID) of the pipe, or slightly retracted inside the coupling.
December 2003 Use the following formula to determine the P dimension: [ID + 2(WT)]/(cos MA) + 2(CL - FD) = P Dimension For example, given the following: • a stack inside diameter of 48 in. • wall thickness of 3/8 in. • installed coupling length of 2.0 in. • a transducer face depth of 1.75 in. • 45 degree mounting angle The P dimension would be [48 in. + 2(3/8 in.)]/(0.7071) + 2(2.0 in. - 1.75 in.) = 69.4 in.
December 2003 Appendix C Serial Connections The TransPort can transmit stored data and displayed readings using the RS232 communication port. In order to enable the TransPort to communicate properly, you must use the proper cable. Panametrics provides the following cables which are compatible with most computer or serial devices (see Table C-1). Table C-1: Serial Port Cables Cable Part # Connector Description Cable Length Typical Device 26DLC/9F-6 “D” Type, 9 pin female contacts 1.8 m (6 ft) 3.
December 2003 If you wish to construct a suitable cable, use the information in Table C-2 to make the RS232 pin connections.

December 2003 Appendix E Temperature Transmitter Installation The TransPort requires a supply and return temperature input to measure energy rate and consumption. You must connect the temperature sensors to a 4 to 20 mA transmitter (powered by the TransPort or externally) and then from the transmitter to the TransPort (a special GE Panametrics cable is required to make transmitter to TransPort connections).
December 2003 Guidelines for RTD Installation You should have discussed possible installation sites with an applications engineer or field sales person by the time you receive the RTDs. However, you should follow these guidelines to ensure accurate temperature measurement: • Do not install the RTD on a pipe seam. • Clean the pipe at the installation location. • Do not install the RTD on the top or the bottom of the pipe. • Apply thermal couplant to the RTD before mounting it to the pipe.
December 2003 Assembling the Clamping Fixture (cont.) 5. Each RTD has a securing post (located on the rounded portion of the RTD) that secures the RTD in place when it is mounted on the pipe. Place the RTD on the strap by sliding the strap under the securing post. IMPORTANT: Make sure you place the RTD on the strap so when the strap is wrapped around the pipe, the flat surface of the RTD sits against the pipe. 6.
December 2003 Making Electrical Connections The TransPort will not accept a signal directly from the RTD; therefore, you must have some type of 4 to 20-mA transmitter. GE Panametrics supplies a dual transmitter (DTR) with a special LEMO connector that attaches to the TransPort. The TransPort supplies power to the DTR using an internal 16 V supply.
December 2003 Connecting the Transmitter to the TransPort If you are using the GE Panametrics DTR, simply plug the LEMO connector into the ANALOG I/O connector as shown in Figure E-1.

December 2003 Appendix F Ultrasonic Thickness Gage Theory of Operation All ultrasonic thickness gaging involves timing the round trip of a sound pulse in a test material. Because solid metal has an acoustic impedance that differs from that of gasses, liquids, or corrosion products such as scale or rust, the sound pulse will reflect from the far surface of the remaining metal.
December 2003 Factors Affecting Performance and Accuracy A. Surface Condition - Loose or flaking scale, rust, corrosion or dirt on the outside surface of a test piece will interfere with the coupling of sound energy from the transducer into the test material. Thus, any loose debris of this sort should be cleaned from the specimen with a wire brush or file before measurements are attempted.
December 2003 Factors Affecting Performance and Accuracy (cont.) As with any difficult application, experimentation with actual product samples is the best way to determine the limits of a particular gage/transducer combination on a given surface. B. Transducer Positioning/Alignment - For proper sound coupling the transducer must be pressed firmly against the test surface.
December 2003 Factors Affecting Performance and Accuracy (cont.) Remember that an ultrasonic test measures thickness at only one point within the beam of the transducer, and that in corrosion situations wall thicknesses often vary considerably. Test procedures usually call for making a number of measurements within a defined area and establishing a minimum and/or average thickness.
December 2003 Factors Affecting Performance and Accuracy (cont.) D. Taper or Eccentricity - If the contact surface and the back surface are tapered or eccentric with respect to each other, the return echo again becomes distorted and the accuracy of measurement is diminished. E. Acoustic Properties of the Material - There are several conditions found in engineering materials that can severely limit the accuracy and thickness range that can be measured. 1.
December 2003 Appendix G Screen and Error Messages This appendix contains the common screen and error messages that may appear on the TransPort screen either while the unit is making measurements or while you are performing a task.
