The paper puts forward a method of combining round cylinder pressure drop - turbine meter for measuring gas - lipuid flow in a duct. The characteristics of this method were investigated in the experiments. By means of computer control,the performance of the experiments with volume fractions β=0. 0,0. 3,0. 5,0. 8 and 1. 0 was measured. Based on the observation and analysis, an equation for the round cylinder pressure drop - turbine meter measurement was developed. A theoretical discussion of the measurement method was presented.
