MULTI-PHASE FLOW METER Russian patent published in 2014 - IPC G01F1/40 

FIELD: measurement equipment.

SUBSTANCE: measurement device (100) and system for measurement of physical properties of separate phases of a multi-phase flow that flows in a pipeline (110), besides, the measurement device (100) comprises a measurement section (120), at least two separate and extended chambers (130), formed at least by one longitudinal barrier (140), besides, at least one of the chambers (130) comprises a facility to measure physical properties of the multi-phase flow flowing through the chambers (130), and in which the internal diameter of the pipeline (110) is less in the location, where the measurement section (120) is located, in which there is a narrowing (220) of inner walls of the pipeline (110). At the same time the facility to measure physical properties of a multi-phase flow includes sensors of pressure (150) for measurement of pressure differences in different locations with different cross sections in the measurement device (100) and electrodes for measurement of electric properties of a multi-phase flow, and in which there is at least one inner electrode (160), connected with a longitudinal barrier (140) and electrically isolated from this barrier (140), at the same time in the inner wall of the pipeline (110) there is at least one external counter electrode (170) built in, electrically isolated from this wall.

EFFECT: maximum sensitivity, minimisation of any effects of an edge field along edges, and accordingly higher accuracy of measurement.
