ABSTRACT:
A meter proving method and system. At lease some of the illustrative embodiments are methods comprising establishing a prover time by a prover device, measuring a flow rate of a fluid with a flow meter that uses multiple measurements taken over a period of time to produce each individual flow rate value (the flow meter electrically coupled to the prover device), and generating a meter volume over the prover time based on the flow rate. The generating the meter volume based on the flow rate does not involve: generating a pulse train output signal by the flow meter; and generating the meter volume based on an attribute of the pulse train.
