Wet gas measurement

摘要

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.

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.
