INTRODUCTION 1.1 OVERVIEW Thank you for purchasing the PT900 ultrasonic flow meter. PT900 is a portable transmitter for measurement of liquids phase product.  It’s designed for the industrial market including water, wastewater, steel, campus energy etc. PT900 will utilize a new electronics platform and industrial design to make it extremely simple to install and use in the field.  The PT900 consists of a transmitter with electronics, CRR transducers system including the new clamp-on fixture and cable.   The PT900 system will also have optional accessories including a thickness gauge, clamp-on temperature transmitters, and a fixture for up to 48”.  PT900 system will connect via Bluetooth to a separate display (tablet) for programming.                          Figure 1: PT900 system (Pipe Mounting)

They are in acoustic communication with each other, meaning the second transducer can receive ultrasonic signals transmitted by the first transducer and vice versa.  In operation, each transducer functions as a transmitter, generating a certain number of acoustic pulses, and then as a receiver for an identical number of pulses. The time interval between transmission and reception of the ultrasonic signals is measured in both directions. When the liquid in the pipe is not flowing, the transit-time downstream equals the transit-time upstream. When the liquid is flowing, the transit-time downstream is less than the transit-time upstream.  The difference between the downstream and upstream transit times is proportional to the velocity of the flowing liquid, and its sign indicates the direction of flow.

Also there needs to be a section in the manual that pertains to batteries, wiring, APP installation and necessary software/hardware platforms for installation purposes. Other sections can be noted in PT878 manual.] 2.4.1 Mounting the Bracket   Figure 6: Pre-Assembly Process  Before mounting, check that the screw mechanisms (chain mechanism screws) that are pre-attached to the end pieces (end flats) are unscrewed to their full potential [A] and that the last joint in the chain is secured within the chain mechanism screw slot on both sides of the fixture [B]. It is highly recommended that the pin is engaged securing the bottom portion of the clamp mechanism to the top portion [C] and that the thumb screw is tightened on the movable clamp [D] so that no motion is allowed throughout the mounting process.    Figure 7: Distance Parameters Adjust the bracket position so that the closest end flat rests at the preferred distance from inlet/outlet/joint/fitting of the pipe.

 Contents PT900 User’s Manual                                                                                                                                                                                                                12  IMPORTANT:  There must be allotted a straight run of at least 10 diameters (nominal pipe diameters) before the upstream transducer and, preferably, at least 5 diameters after the downstream transducer. A clearance of at least 6in should be provided from the edge of each end flat to the nearest joint/welding/flange. Please see figure 2.2 for clarification.  Place the fixture so that minimal effort is required to maintain the fixture position (e.g. even if horizontal positioning is eventually preferred, place the bracket on top of the pipe for mounting). Check that the pipe rests in the small slot cutout on the bottom edge of the end flats.  Note:  Make sure to mount the bracket with the final orientation in mind so that the markings on the rail rod can be easily read.    Figure 8: Chain Connection  While holding the end flat closest to the pivotal inlet/outlet/joint/fitting, loop the metal chain around the pipe so that it wraps all the way around. Pull the chain firmly, without compromising the brackets position, and force the chain to slide into the small slot located at the opposite side of the end flat from the chain mechanism screw [E].   Repeat this process for the opposite chain so that the bracket is firmly mounted but has enough leeway to be able to adjust bracket alignments.  Adjust the bracket into the preferred orientation on the pipe. Re-center the end flats on the pipe using the small slot cutout on the bottom edge of the end flats as a tangent-to-pipe indicator. (Level may be necessary, depending on accuracy required, to verify that the bracket is aligned down the center of the pipe.)  Once aligned, tighten the chains by twisting the nut on top of both chain mechanisms’ screws until the chain is tight enough to resist the bracket’s movement [A, Figure 2.1]. Verify that this extra restraint did not affect the center alignment. If this is the case, loosen the nuts, realign, and tighten the screws until the bracket is aligned and secured tightly.  2.4.2 Installing the Transducers Bracket Before installing the transducers, the transducer holder must be attached to the transducer. In many cases, the transducer holder will already be installed when shipped. If this is the case, skip to section 2.4.3 for installation of the transducers. E End Flat Chain Screw  Mechanism

In order to attach the transducers to their holder, slide the holder onto the top of the transducer so that the circle slots near the top of the transducer sides are closely aligned with the filled holes on the side of the transducer holder.   Screw the hex socket set screws from the transducer housing into the holes of the transducer. Once tightened, these screws will lock the housing into place.  See Figure 2.4 for clarification.  Figure 9: Transducer Assembly 2.4.3 Installing the Transducers If necessary, unscrew the thumb screw on the movable clamp to permit axial positioning.  Position the movable bottom clamp so that it rests at the measurement marking matching that of the preferred axial distance. Measurement markings should be read on the side of the clamp indicated by the arrows.  Note:  Distance between transducers vary based on pipe dimensions, number of traverses, wall thickness, etc. APP can automatically calculate distance and help to position the transducer at a preferred distance for optimal signal quality (described further in Chapter 3.6.5).  Tighten the thumb screw to lock movable clamp into place while being cautious not to adjust set axial positioning.

IMPORTANT:  Slide the transducers into place with an orientation so that the wire connector is pointed away from the opposing clamp. In other words, the wire connectors should be oriented in opposite directions. The arrows on the end flats help to indicate the wire connector direction if needed.                                                      Apply proper coupling to both of the transducer bottoms to help remove air impurities from readings and supply a more fluent contact with the pipe.  Note:  Water based lubricant is not recommended for heated, long term, or multiple traverse measurements.  Swing both of the top portions of the clamp back into alignment with the clamp bottom and lock them back into place by sliding the pin through the hole on the side of the top portion into the hole on the side of the bottom clamp.

Caution! While releasing the cam, make sure that you are not making any contact with the clamp surface. Potential that stored energy acting on cam will cause cam to make hard contact with clamp face. Objects or body parts in between contact faces could result in minor injuries.

Please refer to Appendix E for all kinds of supported transducer type.  If user have selected a standard transducer, the PT900 APP will display programmed with the needed parameters.  If user have selected a special application transducer “Other”, all parameters need to be edited.  The FREQUENCY option defines to transmit a signal at a frequency to which the transducer can respond. The drop-down list consists five options, ranging from 0.25MHz to 4MHz.  The TW option defines the time delay, which is actually the time the transducer signal spends travelling through the transducer and cable. The PT900 calculates the flow rate from the upstream and downstream transit times in the fluid, so the TW must be subtracted out for an accurate measurement. The factory supplies the time delay on a sheet of paper inside the transducer case.  If user have selected Clamp-On transducer, three more inputs are required: WEDGE ANGLE, WEDGE TEMPERATURE and WEDGE SOUND SPEED. But if transducer is standard, WEDGE ANGLE and WEDGE SOUND SPEED is supplied by PT900. Only WEDGE TEMPERATURE needs to be input. 3.6.4.2 REYNOLDS Correction Factor If the user turn the REYNOLDS CORRECTION FACTOR to ON, this correction factor will be effective in most application, including all those that utilize clamp-on transducers. It makes a small adjustment to the flow rate reported by the PT900. Reynolds Correction is necessary, as the velocity of the fluid measured along a diametrical path must be related to the total area average velocity over the entire pipe cross-section. 3.6.4.3 Meter Factor Click the METER FACTORS button, a menu will pop up like below.

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 PT900 uses various digital signal processing techniques, including cross-correlation, to determine transit times and then uses the transit times to calculate flow velocity.   With this time-different technique, flow velocity would be calculated accurately. During this signal processing, many related variables could be measured. And all these variables are useful to monitor the working status of the PT900 and the field instrument.  So PT900 application provides user a powerful function to monitor all different variables in real-time. From the side bar menu, select the   MEASURE option, variable measurement results would be showed like below figure 42.   All value displayed is the real-time measurement. But if system is OFFLINE, the value would always be the last got number when previous ONLINE.

If turn on the power saving mode, MEASUREMENT TIME and SLEEP TIME need to be configured.  o MEASUREMENT TIME supports 5 selections, 5min/10min/20min/30min/60min. o SLEEP TIME supports 8 selections, 30min/60min/90min/120min/150min/180min/210min/240min. o If MEASUREMENT TIME is 5 min, and SLEEP TIME is 30 min, the PT900 transmitter would measure for 5 minutes and sleep for 30 minutes in alternation.  The PEAK DETECT option enables the user to check the method to identify the peak of the received signal. The PT900 transmitter supports two different methods, PEAK method and THRESHOLD method. o In the PEAK method, the peak is identified by testing a derivative of the signal. The peak method is more reliable in identifying the signal in dynamic conditions. o In the THRESHOLD method, the peak is identified as the point where the signal crosses a threshold that is a percentage of the maximum signal detected. The threshold method is more reliable in marginal signal conditions.  If THRESHOLD method is selected in PEAK DETECT, the THRESHOLD DETECT is also need to be configured. There are two methods that THRESHOLD DETECT supports, Auto and Manual. o In Auto method, threshold would be detected by transmitter automatically. o In Manual method, minimum and maximum threshold percentage (available from 0 to 100) need to be input. And peak percentage is also required.  The DELTA T OFFSET is the difference between the upstream and downstream transit time of the transducer. And the delta-T offset value should normally be set to zero.  The ZERO CUTOFF enables the user to set the offset near “zero” flow. Near a zero flow rate, the PT900’s readings may fluctuate due to small offsets caused by thermal drift or similar factors. To force a Zero display reading, when there is minimal flow, enter a zero cut-off value is required.  Finally, don’t forget to click the SAVE button.  3.9.4 How to test meter The TEST option enables the customer to ensure that the PT900 is performing properly. Two test methods are supported: o Watchdog Test o Wave Snapshot.

If measured velocity falls outside these limits, the VELOCITY RANGE error message appears in measurement screen.  Second, low and high limits for the AMPLITUDE discriminator are required to be input. The amplitude discriminator measures the size of the transducer signal sent from the PT900. If the signal falls outside these limits, the AMPLITUDE ERROR message appears.  Third, the acceptable limits for the SOUND SPEED, which based on conditions in customer’s particular system, are required. The SOUND SPEED ERROR message appears if the fluid sound speed exceeds that entered in the FLUID option of the PROGRAM menu by more than this percentage. The default value is 20% of the nominal sound speed.  Fourth, the ACCELERATION limit for detecting cycle skipping is required. The CYCLE SKIP ERROR message appears if the velocity changes by more than this limit from one reading to the next.

ERROR CODES AND TROUBLESHOOTING  4.1 ERROR DISPLAY IN THE MEASUREMENT In MEASURE interface, the top middle line of the APP displays top priority error message during operation. This line, called the Error Line, includes two parts: Error Channel and Error String. The Error channel indicates the error occurs in which channel, while the Error string gives a detailed description of the error information  4.1.1 Error Channel  Error Channel Error Header Channel 1 CH1 Channel 2 CH2 Meter No specified channel  4.1.2 Flow Error String Flow errors are errors in the course of making a flow measurement. These errors can be caused by disturbances in the fluid, such as excessive particles in the flow stream or extreme temperature gradients. The errors could also be caused by an empty pipe or other such issue with the fluid itself. Flow errors are typically not caused by a malfunction of the flow measurement device, but by an issue with the fluid itself.  4.1.2.1 Low Signal Problem: Poor ultrasonic signal strength or the signal exceeds the limit via the Program; Cause: When SNR is less that the value of “Signal Low Limits” or the signal cannot be found when the flow is started, the Low Signal error will occur. Poor signal strength may be caused by a defective cable, a flowcell problem, a defective transducer or a problem in electronic console. A signal that exceeds the programmed limits is probably caused by the entry of an improper value in the menu Transmitter  Service  Error Limits Signal Low limits ; Action: Check the components listed above (Refer to 4.2 Diagnostics). Also check the inputted value in the menu Transmitter  Service  Error Limits Signal Low limits;  4.1.2.2 Sound Speed Error Problem: The sound speed exceeds the limits programmed in the menu Transmitter  Service  Error Limits SOUND SPEED +- limits; Cause: When the measured sound speed is out of the limit of sound speed, it will cause this error. The error may be caused by incorrect programming, poor flow conditions and poor transducer orientation; Action: Correct the programming errors. Refer to 4.2 Diagnostics, to correct the flowcell and/or transducer problems. . Also check the inputted value in the menu Transmitter  Service  Error Limits SOUND SPEED +- limits;   4.1.2.3 Velocity Range Problem: The velocity exceeds the limits programmed in the menu Transmitter  Service  Error Limits Velocity MIN/MAX LIMIT; Cause: When the measured velocity is out of the limit of velocity, it will cause this error. The error may be caused by improper programming data, poor flow conditions and/or excessive turbulence;

Also, check the entered value in the menu Transmitter  Service  Error Limits Velocity MIN/MAX LIMIT. Refer to 4.2 Diagnostics, to correct the flowcell and/or transducer problems.  4.1.2.4 Signal Quality Problem: The signal quality is outside the limits programmed in the menu Transmitter  Service  Error Limits Correlation Peak; Cause: The peak of the upstream or downstream correlation signals has fallen below the correlation peak limit, as set in the menu Program  Advanced  Error Limits Correlation Peak. This may be caused by a flowcell or electrical problem. Action: Check for sources of electrical interference and verify the integrity of the electronics console by temporarily substituting a test flowcell that is known to be good. Check the transducers and relocate them, if necessary. See 4.2 Diagnostics, for instructions.  4.1.2.5 Amplitude Error Problem: The signal amplitude exceeds the limits programmed in the menu Transmitter  Service  Error LimitsAmp Disc Min/Max; Cause: Solid or liquid particulates may be present in the flowcell. Poor coupling for the clamp-on transducers; Action: Refer to 4.2 Diagnostics, to correct any flowcell problems;  4.1.2.6 Cycle Skip Problem: The acceleration exceeds the limits programmed in the menu Transmitter  Service  Error LimitsAcceleration; Cause: This condition is usually caused by poor flow conditions or improper transducer alignment; Action: Refer to 4.2 Diagnostics, to correct any flowcell and/or transducer problems   4.2 DIAGNOSTICS 4.2.1 Introduction This section explains how to troubleshoot the PT900 if problems arise with the electronics enclosure, the flowcell, or the transducers. Indications of a possible problem include:  Display of an error message on the tablet measure screen.   Erratic flow readings  Readings of doubtful accuracy (i.e., readings that are not consistent with readings from another flow measuring device connected to the same process). If any of the above conditions occurs, proceed with the instructions presented in this chapter.  4.2.2 Flowcell Problems If preliminary troubleshooting with the Error Code indicates a possible flowcell problem, proceed with this section. Flowcell problems fall into two categories: fluid problems or pipe problems. Read the following sections carefully to determine if the problem is indeed related to the flowcell. If the instructions in this section fail to resolve the problem, contact GE for assistance.
 Contents PT900 User’s Manual                                                                                                                                                                                                                76 4.2.2.1 Fluid Problems Most fluid-related problems result from a failure to observe the flow meter system installation instructions. Refer to Chapter 2, Installation, to correct any installation problems.  If the physical installation of the system meets the recommended specifications, it is possible that the fluid itself may be preventing accurate flow rate measurements. The fluid being measured must meet the following requirements:  1. The fluid must be homogeneous, single-phase, relatively clean and flowing steadily.  Although a low level of entrained particles may have little effect on the operation of the PT900, excessive amounts of solid or gas particles will absorb or disperse the ultrasound signals. This interference with the ultrasound transmissions through the fluid will cause inaccurate flow rate measurements. In addition, temperature gradients in the fluid flow may result in erratic or inaccurate flow rate readings. 2. The fluid must not cavitate near the flowcell.  Fluids with a high vapor pressure may cavitate near or in the flowcell. This causes problems resulting from gas bubbles in the fluid. Cavitation can usually be controlled through proper installation design. 3. The fluid must not excessively attenuate ultrasound signals.  Some fluids, particularly those that are very viscous, readily absorb ultrasound energy. In such a case, an error code message will appear on the display screen to indicate that the ultrasonic signal strength is insufficient for reliable measurements. 4. The fluid sound speed must not vary excessively.  The PT900 will tolerate relatively large changes in the fluid sound speed, as may be caused by variations in fluid composition and/or temperature. However, such changes must occur slowly. Rapid fluctuations in the fluid sound speed to a value that is considerably different from that programmed into the PT900, will result in erratic or inaccurate flow rate readings. Refer to “Chapter 3, Initial Setup and Programming” and make sure that the appropriate sound speed is programmed into the meter.  4.2.2.2 Pipe Problems Pipe-related problems may result either from a failure to observe the installation instructions, as described in Chapter 2, or from improper programming of the meter. By far, the most common pipe problems are the following:  1. The collection of material at the transducer location(s).  Accumulated debris at the transducer location(s) will interfere with transmission of the ultrasound signals. As a result, accurate flow rate measurements are not possible. Realignment of the flowcell or transducers often cures such problems, and in some cases, transducers that protrude into the flow stream may be used. Refer to Chapter 2, Installation, for more details on proper installation practices. 2. Inaccurate pipe measurements.  The accuracy of the flow rate measurements is no better than the accuracy of the programmed pipe dimensions. For a flowcell supplied by GE, the correct data will be included in the documentation. For other flowcells, measure the pipe wall thickness and diameter with the same accuracy desired in the flow rate
 Contents PT900 User’s Manual                                                                                                                                                                                                                77 readings. Also, check the pipe for dents, eccentricity, weld deformity, straightness and other factors that may cause inaccurate readings. Refer to Chapter 3, Initial Setup, for instructions on programming the pipe data.  In addition to the actual pipe dimensions, the path length (P) and the axial dimension (L), based on the actual transducer mounting locations, must be accurately programmed into the flow meter. For a GE Sensing flowcell, this data will be included with the documentation for the system. If the transducers are mounted onto an existing pipe, these dimensions must be precisely measured. 3. The inside of the pipe or flowcell must be relatively clean.  Excessive buildup of scale, rust or debris will interfere with flow measurement. Generally, a thin coating or a solid well-adhered build up on the pipe wall will not cause problems. Loose scale and thick coatings (such as tar or oil) will interfere with ultrasound transmission and may result in incorrect or unreliable measurements.  4.2.3 Transducer Problems Ultrasonic transducers are rugged, reliable devices. However, they are subject to physical damage from mishandling and chemical attack. The following list of potential problems is grouped according to transducer type. Contact GE if you cannot solve a transducer-related problem.  4.2.4 Bluetooth Connection Problems The communication between transmitter and tablet is based on Bluetooth, which is a wireless protocol. So if the distance between the transmitter and tablet is too big or they are blocked by some solid thing, such as a big wall, the communication will be bad. In this case, some false negatives would occur. Please move your body to near the transmitter first.

COMMUNICATION 5.1 MODBUS 5.1.1 Introduce In general, the PT900 flow meter follows the standard Modbus communications protocol defined by the reference MODBUS APPLICATION PROTOCOL SPECIFICATION V1.1b. This specification is available at www.modbus.org on the Internet. With this reference as a guide, an operator could use any Modbus master to communicate with the flow meter.  Listed below are two limits of this implementation:  1. The PT900 supports only four of the standard function codes. These are Read Holding Registers (0x03), Read Input Registers (0x04), Write Multiple Registers (0x10), and Read File Record (0x14). 2. The flow meter needs a 15 ms gap between Modbus requests. The prime objective of the flow meter is to measure flow and drive the output, so the Modbus server has a low priority.  5.1.2 MODBUS Map    Register (in Hex) Register (in Decimal) Access Level Description RO/RW Format 100 100 256 User Product Short Tag RW CHAR * 16  108 264 User Product Long Tag RW CHAR * 32  118 280 User eAI1Label RW CHAR * 16  120 288 User eAI2Label RW CHAR * 16  128 296 User eLogName RW CHAR * 16  130 304 User Product Electronical serial number RW CHAR * 16  138 312 User Product fixture serial number RW CHAR * 16  140 320 User Product transducer1 serial number RW CHAR * 16  148 328 User Product transducer2 serial number RW CHAR * 16  150 336 User Product transducer3 serial number RW CHAR * 16  158 344 User Product transducer4 serial number RW CHAR * 16  160 352 User eUserFunc1Lable RW CHAR * 8  164 356 User eUserFunc2Lable RW CHAR * 8  168 360 User eUserFunc3Lable RW CHAR * 8  16C 364 User eUserFunc4Lable RW CHAR * 8  170 368 User eUserFunc5Lable RW CHAR * 8  174 372 User eUserFunc1Unit RW CHAR * 8  178 376 User eUserFunc2Unit RW CHAR * 8  17C 380 User eUserFunc3Unit RW CHAR * 8  180 384 User eUserFunc4Unit RW CHAR * 8  184 388 User eUserFunc5Unit RW CHAR * 8  188 392 User eTabALable RW CHAR * 8  18C 396 User eTabBLable RW CHAR * 8

To protect the product and user data safety, a private protocol is structured based on common Bluetooth 4.0 protocol.  And PT900 flow meter does not support display screen and keypad, so it cannot use Numeric Comparison and Passkey Entry.
