Study on measurement of oil gas water three phase flow with conductance correlative flow meter

Since oil gas water three phase flow is a complex process, it is quite difficult to measure its parameters. Most of single phase flow meters do not fit for three phase. A conductance correlative flow meter is studied for three phase flow measurement. The experiment results show that this method is feasible. And the applying technique conditions are that water volume ratio of liquid is more than 50%, gas volume ratio is less than 40% , and the flow rate is not less than 1 m/s. Under the conditions, the maximum measure error is less than plusmn 5%.
