Method and apparatus for calibration of electronic gas meters
Patent
·
OSTI ID:6467243
This patent describes a method for calibration of a fluid flow meter and the like. It comprises: supplying a gaseous test fluid to the meter under test in a series of different known flow rates; measuring the volume flow rate of the test fluid supplied to the meter and the time taken at each flow rate using a volume measurement standard apparatus and a timing means; enabling the meter under test to measure the volume flow rate of the fluid which flows through the meter at each test flow rate and recording the volume flow rate measured by the meter at each test flow rate; and deriving from the recorded and measured fluid flow rates obtained for each test flow rate, data for use in the calibration of the meter.
