FIELD: physics.
SUBSTANCE: vibration meter for measurement of three-phase flow comprises meter design assembly comprising strain gages and measuring electronic circuitry connected therewith. Note here that said vibration meter incorporates said electronic circuitry configured to receive response signal from strain gages, to generate first measurement of three phase flow density and at least second measurement of three phase flow density. Note here that vibration response signal frequency first component is used for generation of the first measurement while vibration response signal frequency second component is used for generation of the second measurement, second frequency component being different from the first one. Vibration meter comprises also the determination of phase components and one or more flow parameters from the first measurement of density and at least second measurement of density.
EFFECT: ruling out of major errors of entrapped gas in calculation of net oil.
