5.3 Meter proving
The public utility commissions or various governmental regulations may require you to check the accuracy
of the actual volume of gas flowing through a gas meter. Prover devices such as the Dresser Model 5
Prover and the Elster/American Meter SNAP Sonic Nozzle Prover are used for verifying the accuracy of the
volume of gas flowing through a gas meter. Prover devices pass a known volume and temperature of gas
through the meter being tested. They compare their own standard volume to the volume reported by
EC350, which is mechanically connected to the rotary gas meter.
EC350 uses switch closure pulse counts for providing volume data to the Prover device. The meter bodies
and EC350 are tested at various rates such as 10%, 50%, and 100% of rated capacity. You can connect
EC350 to a prover to test both uncorrected and temperature corrected volumes.
EC350 has a special operating mode that makes meter proving process very easy and fast. This mode is
called Pushbutton Proving . No special configuration settings are required to use the Pushbutton Proving
feature of EC350.
