Method and apparatus for proving electronic gas meters

摘要

A method and apparatus for proving an electronic gas meter and the like that includes counting the number of pulses provided by an encoder associated with a bell prover to define a volume of test fluid which is supplied to the meter under test, enalbing the meter to measure the volumetric fluid flow rate and integrating the volumetric flow rate of test fluid measured by the gas meter during the test, and data representing the actual volume of test fluid supplied to the meter under test to determine the percent proof or accuracy of the meter.
