WET GAS MEASUREMENT
First Claim
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 a measure of wetness of the multi-phase process fluid based on a mapping between one or more of the apparent intermediate values and the measure of wetness;
determining a second apparent property of the multi-phase process fluid using the differential pressure flowmeter; and
determining one or more phase-specific properties of the multi-phase process fluid based on the measure of wetness and the second apparent property.

Abstract
A first apparent property of a multi-phase process fluid is determined based on the motion of the vibratable flowtube. One or more apparent intermediate values associated with the multi-phase process fluid are determined based on the first apparent property. A measure of wetness of the multi-phase process fluid is determined based on a mapping between one or more of the apparent intermediate values and the measure of wetness. A second apparent property of the multi-phase process fluid is determined using the differential pressure flowmeter. One or more phase-specific properties of the multi-phase process fluid is determined based on the measure of wetness and the second apparent property.
