ABSTRACT:
A method and apparatus for the calibration of electronic gas meters and the like includes subjecting the meter under test to test fluid at a series of differing known volumetric flow rates, determining the meter response using a bell prover to determine volume flow rate, and using data obtained from the series of tests in the calculation of calibration data which is stored in the memory of the electronic meter for use in subsequent volumetric flow measurement by the meter.
