Patent ID: 7716994

Claim:
A method comprising: passing a multi-phase process fluid through a differential pressure flowmeter, the multi-phase process fluid including at least a first phase and a second phase; measuring a flowrate of the multi-phase process fluid as a single-phase fluid using the differential pressure flowmeter; passing the multi-phase process fluid through a Coriolis flowmeter; measuring a value of a property of the multi-phase process fluid using the Coriolis flowmeter, the measured value including an inaccuracy caused by the multi-phase process fluid passing through the Coriolis flowmeter; correcting the measured value of the property based on the flowrate measured using the differential pressure meter to account for the inaccuracy, thereby generating a corrected value of the property; and determining a flowrate of the first phase or the second phase of the multi-phase process fluid based on the corrected value of the property.
