4 Transfer Prover Operation Introduction The Transfer Prover is a portable proving system designed to provide accurate field proving for rotary, turbine, and diaphragm meters. The compact design allows the prover to be transported to field locations without the need of a dedicated vehicle or multi-person work crews. The prover system s low power design allows testing and blower operation using a standard AC/DC inverter as opposed to the need for a dedicated AC circuit or gas generator. Materials/Tools Needed Pipe Wrenches Small Crescent Wrench Screw Driver Allen Wrenches Assembly Steps: Prepare the site. The prover uses air to measure the meter under test. Therefore the run must be shut in or placed in bypass mode before starting this test. The index or chart on the output drive of the meter under test must be removed. The inlet and outlet sides of the run must be identified, and the proper connectors installed for either an upstream or a downstream test.

Connecting the Electronics XARTU/TP Transfer Prover Manual Copyright 2014 Eagle Research Corporation Page 8

9 Running the Test RTU Interface The following section discusses the keypad interface to the Transfer Prover. These menu options can be accessed using the keypad attached to the front of the enclosure or through Field Manager s Virtual Keypad. Note that the keypad strokes denoted in the following text are enclosed in <> brackets. Those brackets are not on the keypad. There are multiple selection screens at the beginning that enable the user to specify setup options that may change from site to site. In general, these screens have a header in all capital letters on the top line and a list of options on the remaining three lines. A left arrow points to which option is selected. This selection can be changed using the arrows on the keypad. Pressing <ent> saves the selection and advances the display to the next selection menu. At any point the user can abort a setup by pressing <esc>. Doing so will cause the display to return to the first selection screen. The transfer prover remembers the selections made for the previous proof and uses these values as the default selection next time the selection screens are accessed. Baud Rate Screen At any point during the selection menu, the Transfer Prover can be connected to a laptop using Field Manager. When first connected, the Transfer Prover display will show the baud rate. This tells the operator which baud rate to select in Field Manager. Once the baud rate has been noted, press <esc> to return to the beginning of the selection screens. Pressing other buttons at this point may cause the Transfer Prover to inadvertently advance to the next selection screen. XARTU/TP Transfer Prover Manual Copyright 2014 Eagle Research Corporation Page 9

10 Selection Mode The first selection screen allows the user to choose between starting a proof and performing a self test on the prover. At any point during the option selection process or during the proving process, pressing <esc> will return the program to this screen. Start Proof begins the process of configuring a proof test. The next selection screen will be ENTER OPERATOR NAME. Self Test will put the Transfer Prover in a mode that tests its internal components against a specific flow rate. Skip ahead to the section entitled Self Test for more information. Start Proof Mode Enter Operator Name This selection screen can be disabled by Field Manager. If it does not appear on the Transfer Prover display skip ahead to the next selection screen description. With this selection screen, a user can enter their name as the operator which will be stored in history in conjunction with the setup and results of each test. This entry will appear on the summary report generated by Field Manager. The string can be up to 16 alphanumeric characters long. To enter an identifier, the keypad must be used in a manner similar to texting with a cell phone. The following describes each key s function. Most of the keys have multiple items listed, press the key multiple times within two seconds to produce the desired symbol. For instance, pressing <1> three times consecutively with no more than two seconds between each key press will result in a & being displayed on the screen. If two consecutive desired symbols are on the same key, a two second delay must be observed after the first character is on the screen before continuing to the second. XARTU/TP Transfer Prover Manual Copyright 2014 Eagle Research Corporation Page 10

Abc capitalizes the first symbol and leaves the remaining symbols lower case. ABC capitalizes all symbols. 123 turns the keypad into a strictly numbers pad. abc prints all symbols in lower case. Note: on older models and Field Manager Virtual Keypad this key is denoted <+/->. <down arrow, bsp> moves the cursor to the left one space and then clears the current symbol. If the cursor is in the middle of the entry, all symbols to the right of the cursor will be shifted left by one position. <left arrow> moves the cursor one position to the left. <right arrow> moves the cursor one position to the right. <ent> saves the entry as the Meter ID and advances to the next selection screen. <esc> aborts the entry and returns to the SELECT MODE selection screen. One other notable function provided by this text entering function is Insert. To insert, simple move the cursor to the place a symbol addition is needed, and then enter the symbol regularly. Example 1 Pressing <ABC 123> puts the display in number only mode. Then pressing <1>, <0>, <5>, <2>, <3>, <8> will produce the following. Example 2 Pressing <3>, <3>, <2>, <4>, <5>, <5>, <5>, <3>, <3>, <0>, <2>, <2>, <2>, <2> will produce the following when in Abc mode.

12 Enter Meter ID This selection screen can be disabled by Field Manager. If it does not appear on the Transfer Prover display skip ahead to the next selection screen description. With this selection screen, a user can enter a meter identification number that will be stored in history in conjunction with the setup and results of each test. When the proof history is polled from the Transfer Prover, each record can easily be recognized. This entry is the only value displayed with the date and time of the proof in the report generator. Without this value it can be difficult to distinguish each proof. This screen behaves exactly as the selection screen titled ENTER OPERATOR NAME. Enter Meter Name This selection screen can be disabled by Field Manager. If it does not appear on the Transfer Prover display skip ahead to the next selection screen description. This selection screen provides a second description string for a given site. It behaves exactly as the selection screen titled ENTER OPERATOR NAME. Once finished with this screen, press <ent> to proceed to the next selection screen. XARTU/TP Transfer Prover Manual Copyright 2014 Eagle Research Corporation Page 12

13 Master Meter Each Eagle Research Transfer Prover can be configured to support multiple master meters. This selection screen is used to specify which master meter is connected to the Transfer Prover for the current proof. When entering calibration data, it is important to also enter the master meter serial number. This number will appear below the master meter designator. The operator must verify that the electronics box is pared with the proper master meter each time the test is preformed. Choose the appropriate option, and then press <ent> to go to the next selection screen. If the Transfer Prover is only configured for one master meter, this screen will appear for a brief period and then automatically advance to the next screen. Input Option The Transfer Prover comes with a gate box and a push button switch. The gate box is mounted on top of the meter under test s output drive in the same fashion as an Eagle Corrector. The push button option is used when no output drive is available. Choose the input option used for the current test, and then press <ent> to advance to the next selection screen. Temp Comp Meter If the meter under test has a temperature compensated index drive, select yes. Otherwise, select no. Select the proper option, and then press <ent> to go to the next selection screen. XARTU/TP Transfer Prover Manual Copyright 2014 Eagle Research Corporation Page 13

14 Output Drive This selection screen allows the user to specify the output drive of the meter under test. The optional values that appear in the screen can be picked in Field Manager. A different set of optional values can be specified for each master meter. This value is in cubic feet per revolution. After picking the appropriate option, press <ent> to go to the next selection screen. Master Location This selection screen can be disabled by Field Manager. If it does not appear on the Transfer Prover display skip ahead to the next selection screen description. With the Eagle Research Transfer Prover, the master can be placed upstream or downstream of the meter under test. When using pressure compensation, this option is very important as it determines which meter should show a higher uncorrected volume. If the master meter is always located in the same position with respect to the meter under test, this value can be universally specified and this selection screen disabled. Once the correct location is selected, press <ent> to advance to the next selection screen. XARTU/TP Transfer Prover Manual Copyright 2014 Eagle Research Corporation Page 14

15 Leak Detect This selection screen can be disabled by Field Manager. If it does not appear on the Transfer Prover display skip ahead to the next selection screen description. Selecting Skip will simply advance to the Active screen. Choosing Start will lead to the following screen. To understand the ideas behind the leak detection feature and how to arrange the hardware of the Transfer Prover to perform leak detection, see the section entitled Testing Setup for Leaks. Once satisfied that no significant leaks are present, press <ent> to advance to the next screen. Summary Screens Validation Type This selection screen can be disabled by Field Manager. If it does not appear on the Transfer Prover display skip ahead to the next selection screen description. With this selection screen, a user can select if the meter was tested the way it was found or after any changes, how it was left. This will be stored in history in conjunction with the setup and results of each test. When the proof history is polled from the Transfer Prover, each record will state if it was an as found test or as left test. Once the validation type is selected, press <ent> to advance to the next selection screen. XARTU/TP Transfer Prover Manual Copyright 2014 Eagle Research Corporation Page 15

16 Test Volume This selection screen can be disabled by Field Manager. If it does not appear on the Transfer Prover display skip ahead to the next selection screen description. If this value is skipped, the default value specified in Field Manager is used as the test volume. This value defines how much air will flow though the master meter for each proof cycle. Since this is a volume based criteria, the time for different flow rates can vary dramatically. For instance, a test using a 3MR master meter at a flow rate 300 CFH will take 10 times as long as the same test at a flow rate of 3000 CFH. With the gate box this difference is negligible. However, when using the push button option, the user may want to select flow rates that make the test last at least 45 seconds in order to minimize the user input error. After choosing the desired value, press <ent> to go to the next selection screen. Active Screen At this point in the process, the Transfer Prover has been configured for a particular test, the desired flow rate has been specified, and leak testing has been performed. The screen below is referred to as the Active Screen. The first line is a header that specifies the master meter type. The second line is the flow rate as calculated by the master meter. This value updates in real time as the hand valve on the blower hose is adjusted. The third line is differential pressure. This value is in inches of water and refers to the differential pressure between the inlet of the master meter and the inlet of the meter under test. A negative value is a good indication something is not setup correctly or the proof is not properly configured. This item can be disabled in Field Manager in the event pressure compensation is not needed. XARTU/TP Transfer Prover Manual Copyright 2014 Eagle Research Corporation Page 16

17 The fourth line alternates between the field meter temperature (FMT) and the master meter temperature (MMT). The FMT is determined by the external temperature probe connected to the Transfer Prover. The MMT signal is fed into the Transfer Prover through a temperature probe inside the master meter. This pair of values can be disabled in Field Manager. In order to get the best results from the Transfer Prover, the temperatures should be stable. They will most likely not be equal, but should be settled before performing a test. For instance if a meter had gas flowing though it at 60 F, and then a blower begins pulling 75 F air though it, the temperature of the field meter will increase from 60 F to 75 F at a rate proportional to the flow rate. When the flow rate, differential pressure, and flow temperatures are satisfactory, press <ent> to go to the next menu. Countdown Screen The countdown screen keeps the user informed of the progress of a proof as it happens. The Cnts Left parameter shows the user how many counts remain to be received from the meter under test. This value varies depending on the Test Volume selected during the configuration process. The countdown is uniform, and therefore can be used to estimate the time remaining for a given proof. The DP, MMT, and FMT update periodically. This feature provides the user with a way to monitor the progress of the test and gage the stability of the flow parameters during the calculation phase of the proof. Results Screen The results screen show the percent error, percent accuracy, and/or percent proof. The type of error is configurable in Field Manager. This screen can display all three, any two, or just one error. The Accept/Reject flag is used to expedite reporting in Field Manager. Every proof is stored in the RTU history regardless of the Accept/Reject selection. When the history from the Transfer Prover is loaded into Field Manager, this flag is used to determine the default proofs selected for reporting. XARTU/TP Transfer Prover Manual Copyright 2014 Eagle Research Corporation Page 17

18 Press <jump> to reject the history value. Press <ent> to accept the value. After leaving the results screen, the menu returns to the active screen. From here the user can adjust the flow rate and start another proof. The configuration parameters remain the same. Self Test Master Meter Each Eagle Research Transfer Prover can be configured to support multiple master meters. This selection screen is used to specify which master meter is connected to the Transfer Prover for the current proof. Choose the appropriate option, and then press <ent> to go to the next selection screen. If the Transfer Prover is only configured for one master meter, this screen will appear for a brief period and then automatically advance to the next screen. XARTU/TP This screen will only appear briefly. It gives the user a simple way to view the Transfer Prover firmware version. This screen automatically advances to the next screen. Adjust Flow to 1000 CFH XARTU/TP Transfer Prover Manual Copyright 2014 Eagle Research Corporation Page 18

19 This screen delays to give the user time to verify a flow rate of 1000 CFH is running through the master meter. As this is a test of the master meter, it is best to use another device to determine a flow rate of 1000 CFH. This flow rate must be within five percent in order for the self diagnostics to work. Once the flow rate is set, press <ent> to continue to the next selection screen. Testing Prover This screen may last for up to 20 seconds. During this time, the Transfer Prover calculates its own flow rate to verify that all internal settings are correct. It also measures the counts per revolution and verifies that all are evenly spaced. In the event something is not properly connected to perform the test, an error like the following may appear. Under certain conditions the error may be more specific. In those cases please contact Eagle Research Corporation for more information. Flow Rate The flow rate screen shows the user the flow rate calculated by the master meter. Press <ent> to continue. Please Wait XARTU/TP Transfer Prover Manual Copyright 2014 Eagle Research Corporation Page 19

20 This screen creates a pause while the Transfer Prover makes its final calculations and verifications. The pause should not be longer than 10 seconds. If every part of the test is successful, the PASSES screen will automatically appear. If any of the test criteria fails, the FAILS screen will automatically appear. If this screen appears, the Transfer Prover requires some type of adjustment in order to work properly. Pressing <ent> returns to the SELECT MODE screen. Testing for Leaks When performing a leak test, the master meter should be hooked directly to the vacuum and there should be no openings to the atmosphere. The basic idea is if a leak exists, air will be pulled into the leak and through the master meter causing the counts to increase. When the vacuum pump is first engaged and a vacuum is pulled on the system, a few counts will appear on the display. After this initial surge of counts, the rate of counts should decrease significantly. In theory the rate of counts should go to zero, but this is very unlikely in real world conditions. Since a small leak will most likely exist, it is important to define what constitutes an unacceptable leak. An additional consideration for this discussion is that pulling a vacuum as described will induce a differential pressure several inches more than the maximum flow rate under normal proving. Therefore this process can dramatically exacerbate any leak. Furthermore it is important to evaluate where leaks are originating. A leak that lies between the inlet of the upstream meter and the outlet of the downstream meter will cause an increase in the measurement error. Leaks originated outside of this section are not desired, but they do not significantly contribute to the calculation error since they add or subtract equal amounts of volume from both meters. An average proof, with a volume of 10 cubic feet going though a 3M meter at 1500 CFH, will last about 24 seconds. A leak between the meters quantified as one pulse per second in the master XARTU/TP Transfer Prover Manual Copyright 2014 Eagle Research Corporation Page 20

21 meter, could add 0.3% error to the calculation. In reality the leak quantified at full vacuum may actually be at least 3 times smaller at the pressures of a 1500 CFH test. Therefore a more realistic estimation of the leak induced error would be about 0.1%. In either case, both induced errors are significantly smaller than the commonly used pass/fail criteria of +/- 2.0%. Field Manager for Transfer Prover Eagle Research s Field Manager software provides an easy to use interface to the Transfer Prover for modifying the keypad menu structure, storing proving results, and creating reports. The navigation bar located at the top of the window provides fast access to the different options supplied by this user-friendly application. Connecting To connect to the Transfer Prover, first attach the communications cable and watch the display screen above the keypad. The communications baud rate will appear. In Field Manager, press the button in the upper left corner labeled Connect. The following window will appear. In this window select the connection type, which will most likely be Direct. Make sure the proper Communications Port is selected. Choose the Baud Rate indicated on the display when the communications cable was connected. Finally, click on the OK button at the bottom of the window. Field Manager will XARTU/TP Transfer Prover Manual Copyright 2014 Eagle Research Corporation Page 21

22 automatically detect, interview, and connect to the Transfer Prover. After connecting to the Transfer Prover, some questions may be asked, such as changing the Site ID or time. The Site ID will only need to be changed if the value is equal to 1. Choose a value that is greater than 1 but less than XARTU/TP Transfer Prover Manual Copyright 2014 Eagle Research Corporation Page 22

23 Loading and Using Configurations in Field Manager We are now ready to load the configuration from the Transfer Prover into Field Manager. On the navigation bar, select View/Config. Field Manager will use the information collected from the Transfer Prover to populate the edit forms associated with this database. The names given to tabs along the bottom of the window represent the different tools and customizable features available to the user. For example, in the above screen the last 8 tabs can each be modified to be different master meters. Some master meters are preset as the tabs show, while the last two are uncommitted spares. The functionality of these screens is identical. The master meter name is used to select a specific master meter when navigated with the keypad. The Master Meter S/N is used to specify the meter used during the test and also lets the users know to which meter the calibration file is attached. This value appears in the automated report generated by Field Manager. The base pulses are determined in conjunction with the base volume CF. XARTU/TP Transfer Prover Manual Copyright 2014 Eagle Research Corporation Page 23

24 Together they let the Transfer Prover know how many pulses to expect for a given volume. The Enabled check box tells the Transfer Prover if the corresponding master meter is active. All active master meters will be available from the keypad. The output drive options let the Transfer Prover know which options to make available to the user during a proof. The Simulation Flow Rate is the flow value provided to the meter during a self test. The Cal Adjust Units specifies how the user plans to enter the correction parameters. The table of Flow Rates and Cal Adjusts is used to enter the calibration data. As a note of caution, the Transfer Prover will give an error if a flow rate that is outside the bounds of calibration is used. For instance, if a 3M master meter was calibrated down to 300 CFH and a test in the field was run at 297 CFH, the Transfer Prover would flag this test as an error since it could not interpolate the calibration factor. The Configuration tab, shown above, is used to customize the menu options available to the user from the keypad. The following values determine if an option is available to the user: Enable Operator Name Entry, Enable Meter ID Entry, Enable Meter Name Entry, Leak Test Enabled, Up/Down Stream Enable, Test Volume Enable, and Validation Type. The following options are used as default values during the initial test or they are used to specify options not made available to the user: Mode, Master Meter, Field Meter Pulse Option, Output Drive, Temperature Compensated Meter, XARTU/TP Transfer Prover Manual Copyright 2014 Eagle Research Corporation Page 24

25 Leak Test, Master Meter Position, and Test Volume. The option Error Display Type is used to specify how the results are displayed at the end of each test. Several values are used to define the hardware used for a test. These include Pressure Correction Type, Temperature Correction Enable, Analog Input Display Mode, and Gate Box Pulses Per Revolution. Flow Rate Units and TRP Name are reserved for specific applications. For standard applications the values of these parameters are XARTU/TP_1 and Air, respectively.

39 After the calibration has been saved it will return to the main Multi-Point Calibration screen. Calibrating Master Meter Flow A reference meter with a known percent difference will be needed for calibrating the master meter flow. In Field Manager, connect to the unit and click on the View/Config button. Along the bottom of the screen click on the tab of the master meter that is being calibrated. In the left hand column enter in each flow rate that the meter will be calibrated at, starting with Flow Rate 1. In the right hand column click on the drop down box next to Cal Adjust Units. Select the Units that will be used during the calibration process. Set up both meters as you would in a normal proof, with the reference meter as the master meter, and the master meter being calibrated set up as the meter under test. Pick a flow rate and run a proof. Record the value given at the end of the test. Take the known percent difference from the reference meter and add it to the number that was recorded. Enter this value in the right hand column corresponding to the flow rate at which it was tested. Click on the Send All Changes button. When anything in the edit form has been changed, this button will turn red. XARTU/TP Transfer Prover Manual Copyright 2014 Eagle Research Corporation Page 39

40 Run the test again at the same flow rate. The result of this test should match the error from the reference meter at that flow rate. This process might need to be repeated several times until the percent difference matches the error of the reference meter. Continue this process for each flow rate until complete.
