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.
