MULTIPHASE FLOW METER Russian patent published in 2023 - IPC G01F1/58 

FIELD: information-measuring systems.

SUBSTANCE: invention relates to the field of measuring the parameters of the flow of a multi-phase fluid and can be used in information-measuring systems of the oil-producing, oil-refining industries. The multiphase flow meter is a Venturi tube with temperature sensors installed at the confuser inlet and diffuser outlet and pressure sensors installed in the confuser and neck, in the neck wall of which, in the section plane perpendicular to the direction of the multiphase fluid flow, two X-ray transparent windows are made opposite each other, in one of which a radiation source is installed, and in the other - a radiation detector, while in the neck wall in the same sectional plane an additional X-ray transparent window is made, located at an angle of 90° to the axis between the radiation source and the radiation detector, in which an additional radiation detector is installed , and blocks for measuring the proportion of water and the proportion of methanol, including a microwave emitter and a microwave radiation detector, are installed in series at the confuser inlet.

EFFECT: high accuracy of measuring the parameters of a multi-phase fluid flow in various pipeline systems in real time without complicating the design of the device.
