The propagation velocity of a pressure pulse through a gas/liquid mixture flowing in a pipeline can be used for metering purposes. The pressure pulse propagation method is presented and a theoretical model developed for the propagation velocity of pressure pulses through gas/liquid mixtures. Preliminary experimental work on pressure pulse propagation measurements in air/water horizontal slug flow are reported. For these flow conditions, the velocity of a gas/liquid mixture can be obtained directly from time-of-flight measurements to upstream and down-stream stations when the void fraction is in the range 10–85 percent.
