摘要
A multiphase flow metering method comprising the detection of pressure differentials dp1 and dp2 by the respective differential transmitters (3) and (4); the detection of an intermediary volumetric flow rate value QL by an ultrasonic Doppler flow meter (5); and calculating through a microprocessor the gas-liquid ratio n1, watercut WR1, and the respective phase volume flow rates Qg1, Qw1 and Qo1 for gas, water and oil respectively. A multiphase flow meter using the same multiphase flow metering method.
