Simple installation for measurement of two-phase gas–liquid flow by means of conventional single-phase flowmeters

The paper describes a method of measuring the flow rate of the components of a two-phase gas–liquid mixture. The proposed method ensures the separation of two phases using a rather simple modification of pipeline configuration than using separating vessels to achieve this aim. The two components can then be measured using conventional single-phase flowmeters. The errors of the separating and metering installation are about ±(3–4)% in the flow rate range 3:1.
