Examination of turbine flow meter for multiphase flow high gas void fraction

摘要

This paper reports the examination of a turbine flow meter to measure the multiphase flow of gas, oil and water. 2" turbine flow meter has twin-rotors conjunct with a spring together and a homogenizer upstream. We have measured each flowrate of three phases by detecting the rotational speed of turbine blade, differential angle between two rotors, differential pressure of homogenizer and temperature of fluid The experimental results show that the volumetric flowrate of each phase are possible to be measured with an uncertainty within ±10% of full scale by using statistic method while the water cut varies from 0% to 100% and the gas void fraction varies flora 0% to 90%.
