Abstract:
1. A method comprising: passing a multi-phase process fluid through a vibratable flowtube and a differential pressure flowmeter; inducing motion in the vibratable flowtube; determining a first apparent property of the multi-phase process fluid based on the motion of the vibratable flowtube; determining one or more apparent intermediate values associated with the multi-phase process fluid based on the first apparent property; determining one or more corrected intermediate values based on a mapping between the apparent intermediate values and the corrected intermediate values; determining one or more estimated phase-specific properties of the multi-phase process fluid based on the corrected intermediate values; determining a measure of wetness of the multi-phase process fluid based on the one or more estimated phase-specific properties; determining a second apparent property of the multi-phase process fluid using the differential pressure flowmeter; and determining a corrected phase-specific property of a phase of the multi-phase process fluid based on the measure of wetness and the second apparent property.
