Configure Model 5 Prover Software
Set the Model 5 Prover software configuration settings as shown in Figure 74 (1).
Set the TC Options box for Diaphragm TC for all meter sizes as shown in Figure 74 (2).
For more information about the values for the prover configuration, refer to Table 16.
The recommended pulses for the test and test volume are shown in Table 15 according to meter capacity.
Using the provided values allows for a test lasting a minimum of the Factory recommended thirty (30)
seconds. If your Model 5 Prover is not equipped with a 2M master meter, you will not be able to test
below 100 cfh. In this case, the minimum flow rate for testing a meter rated at 1000 cfh is 100 cfh. Use a
minimum of two (2) pulses with a minimum test volume of two (2) cubic feet.
Click the
Start
button to run the prover test as shown in Figure 74 (4).
Adding Test Points
To add test points, fill in the following fields as needed:
•
Enter the appropriate flow rate in the next available Flow Rate column.
•
Enter the appropriate test volume. Suggested values are provided in Table 15.
•
The Drive Rate/PPT value always matches the volume.
•
The remaining boxes in the row automatically populate based on the current prover default settings.
•
Fill in additional rows to add other test points. Always start with the highest flow rate and progress
downward to the lowest flow rate.
Note:
When entering values, always move to the next box by either pressing
Enter
or by
using the cursor. Pressing the
Tab
key causes errors in the test configuration.
