Abstract

FIELD: physics. ^ SUBSTANCE: multiphase working fluid medium is passed through a vibration Venturi tube. Motion is generated in the vibration Venturi tube. A first observable property of the multiphase working fluid medium is determined based on movement of the vibration Venturi tube, and an observable intermediate value associated with the multiphase working fluid medium is determined based on the first observable property. A corrected intermediate value is determined based on the mapping between the observable intermediate value and the previous corrected intermediate value. The phase-dependent phase property of the multiphase working fluid medium is determined based on the corrected intermediate value. ^ EFFECT: high accuracy of determining mass flow and density of each phase of a multiphase fluid medium. ^ 25 cl, 98 dwg
