Method and apparatus for proving electronic gas meters at low flow rates
Patent
·
OSTI ID:7089723
This patent describes a method for proof testing of an electronic fluid flow meter and the like at low flow rates. It comprises: supplying test fluid to the meter under test; measuring the actual volume flow rate of test fluid supplied to the meter using a volume measurement standard apparatus and a timing means associated with the volume measurement standard apparatus for measuring the interval of time taken for the test fluid to pass through the meter; enabling the meter to measure the volume flow rate of test fluid supplied to the meter during the time interval measured by the timing means and to provide data indicative of measured volume flow rate during the time interval; and correlating the measured volume flow rate for the fluid passed through the meter with the actual volume flow rate in proving the operation of the meter.
