Abstract
The performance of turbine flowmeter and Venturi meter in oil‐water two‐phase flow measurement was investigated. Experiments were carried out on horizontal pipelines of 0.5‐inch, 1.0‐inch and 1.5‐inch diameters, with the total flowrate range of 0.9∼4.5m3/h and the oil volume fraction range of 15% ∼ 85%. Experimental results show that the measurement errors of the turbine flowmeter and the Venturi meter obviously increase, whether the static mixer is installed on the experimental loop or not. Also, the non‐homogeneity of the oil‐water two‐phase flow and the swirl flow produced by the static mixer have negative influence on the performance of turbine flowmeter and Venturi meter. Research work further indicates that the oil fraction has significant influence on the measurement results of Venturi meter.
