LIQUID FLOW METER Russian patent published in 2022 - IPC G01F23/30 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measuring equipment, in particular to devices measuring the flow of liquid in a three-component mixture coming from producing wells. The liquid flow meter contains a housing of a cylindrical vertical shape, which is a measuring container with an inlet and outlet pipe. To the left of the housing along the entire length there is a pipe with an inlet and outlet channel of the gas line, and on the opposite side there is a liquid pipe that communicates a measuring tank and outlet pipes that are rigidly connected to the measuring tank. A centering axial shaft is installed inside the measuring tank, on which a float is mounted, with the ability to move along the shaft axis. At the bottom of the axial shaft, there is a valve for communication with the outlet pipe of the liquid and gas discharge line. On the working surface of the housing there are guides along which the float moves up and down, it is also a limiter of the float movement. A radar-type sensor-meter is installed on top of the measuring tank, connected to a controller for data transmission.

EFFECT: invention is aimed to increase the efficiency of measuring the flow of liquid in a three-component mixture without increasing metal consumption, manufacturing costs by effectively measuring the flow of liquid flowing through the pipeline, through the use of the meter housing as a measuring liquid storage tank and the use of a two-phase valve, and expanding the functional application of the flow meter of liquid coming from a production well.
