Abstract (en)

[origin: WO9951943A1] A combination gas meter and regulator (10) is disclosed. The meter (18) is disposed in a high pressure region upstream of the regulator (14). The meter (18) includes an ultrasonic transmitter/receiver arrangement (20a, 20b) that transmits a relatively low frequency ultrasonic signal through a gas flow tube (22). Variations in the time of flight of the signal are used to determine the gas flow. The combination further includes a pressure sensor (24a, 24b) in the high pressure region, the output of the meter being a pressure compensated measurement of the gas flow.
