A sample prover station test result is displayed below to demonstrate an example of
adjusting the calibration.
Note: Depending on the meter's firmware version, FDM may accept flow rate entries
only in a whole number format or it may accept flow rate entries of up to two decimal
places.
7. Use the following settings to adjust the meter calibration as it relates to your test results:
Prover station mode. Use the drop-down menu to select the % in which your prover
station results are expressed:
–
(Example selection) % Error
–
% Accuracy
–
% Proof
Prover flow rate unit. From the drop-down menu, select the flow rate unit:
–
(Example selection) Imperial (cubic feet per hour)
–
Metric (cubic meters per hour)
Prover flow rate check. Enter the prover station check flow rate. This is typically 20-35% of
the meter capacity. (Example entry 50)
