WET GAS MEASUREMENT Russian patent published in 2013 - IPC G01F1/84 

FIELD: measurement equipment.

SUBSTANCE: first apparent property of multiphase process fluid medium is determined based on movement of an oscillatory movable flow tube. At least one apparent intermediate value corresponding to multiphase process fluid medium is determined based on the first apparent property. At least one corrected intermediate value is based on conversion of connection between apparent intermediate values and corrected intermediate values. At least one phase-dependent property of multiphase process fluid medium is determined based on corrected intermediate values. Degree of humidity of multiphase process fluid medium is determined based on at least one phase-dependent property that is determined based on corrected intermediate values. The second apparent property of multiphase process fluid medium is determined using a variable pressure drop flow metre. Phase-dependent property of phase of multiphase process fluid medium is determined based on degree of humidity and the second apparent property.

EFFECT: improving wet gas measurement accuracy.
