Method and apparatus for determining the gas flow rate of a gas-liquid mixture |
摘要 |
A method and apparatus are provided for determining the gas flow rate of a gas-liquid mixture which has a gas volume fraction (GVF) of at least 85% and which is conveyed along a conduit. The conduit is fitted with a differential pressure flow meter and a fluid densitometer. The method comprises: measuring the pressure difference across the differential pressure flow meter and measuring the density of the mixture using the densitometer; estimating the GVF of the mixture from the measured density; and calculating the gas flow rate from the measured pressure difference and measured density. A corrective term which comprises the estimated GVF is used in the calculation to correct the gas flow rate for the high GVF value of the mixture.
