All Provers except 2M/10M: Allow time for the main valve to close prior to pressing the Start button.The
Prover Self Test is a short system test. Information is sent to the Controller and a test is started with a flow
rate of approximately 50 percent of the Master Meter’s capacity. Specific results are expected at the end of
the test. If the results of the test vary from the expected values by more than a slight percentage, a failed
message will be displayed. If the test results are as expected, a passed message is displayed. This does
not test the Field Meter pulser components, but the field cable must be connected to the Controller and the
Field Meter temperature probe must be connected to the Field Meter junction box.
The Prover hose should not be connected to the Field Meter in order to prevent any possibility of
over-speeding the Field Meter.
Refer to Prover Self Test in the Help Directory for additional information.
10.3 Master Meter Differential Pressure Test
Refer to Master Meter Differential Pressure Test in the Help Directory for additional information.
Select “Master Meter Differential Pressure Test” from the pull-down menu under the Hours of Operation.
This test measures the differential pressure between the Master Meter inlet pressure transducer
(blue 1/4" pressure line) and the Master Meter outlet pressure transducer (black 1/4" pressure line)
at the entered flow rates. Normally this test is run with no hose or Field Meter connected to the
Master Meter being tested.
You have the choice of running a factory preconfigured test sequence or a custom test in which you will
be prompted to enter the Prover capacity and desired flow rates manually. Enter these flow rates into the row
of gray boxes that runs across the screen. The test will start and display the differential pressure between the
inlet and the outlet of the selected Master Meter. The differential pressures are calculated
for the approximate flow rates entered during the differential pressure test’s configuration and displayed
on the left side of the computer’s screen. Differential pressure test results are dependent on how the
meter is connected.
After successful completion of the differential test, a box will appear that will signal completion.At this
point you can print/save the data. The file will be stored in a comma delimited text file in the Data
subdirectory under the Model 5 Transfer Prover directory that was created when this software
was installed.
10.4 System Leak Test
Refer to Leak Test in the Help Directory for additional information.
Select “System Leak Test” from the pull down menu directly under the Hours of Operation. Perform a
leak test to help determine if and where a leak is present in the Prover system. Leakage during a Field Meter
test will result in a lower Accuracy (higher Corrected Proof) reading than that typically expected. The volume
registered by the meter under test is compared to the volume registered by the Master
Meter. In an Automatic test, the Field Meter starts and stops the test according to the test volume
selected in the software configuration. Perform a leak test using either the automatic vacuum test or
positive pressure method.
Important:
Place a Dust Cap over the inlet of the Field Meter and secure in place. If a Dust Cap is not
available, use a mating flange and gasket, or other method that will produce an air tight seal at the
opening of the Field Meter inlet.
