METHOD FOR MEASURING FLOW RATE OF LIQUID CARRIER USING CORIOLIS EFFECT Russian patent published in 2024 - IPC G01F1/84 

FIELD: instrumentation.

SUBSTANCE: invention relates to instrument making, namely to devices for measuring mass flow of liquid carriers. Disclosed is a method for measuring flow rate of a liquid carrier using the Coriolis effect, according to which inside the housing there is a rotor assembly with a central shaft of rotation and a plurality of radial channels from the outer circumference of the rotor assembly to the central cavity of the rotor assembly, rotor assembly is made of two coaxial cylinders fastened by end covers, radial channels are located in one plane, inner cylinder is fixed on a horizontal shaft, which is mounted in rotary bearings installed in a closed housing enclosing the rotor assembly with a minimum gap and having inlet and outlet holes in the plane of radial channels along a horizontal line passing through the axis of rotation, flexible pipelines are connected to the holes, flow rate of liquid carrier is measured by dynamometer loaded with housing and rotor assembly. A diaphragm of variable diameter is installed behind the outlet hole and the diaphragm diameter is adjusted based on the condition of equality of pressure of the liquid carrier in the outlet and inlet pipelines.

EFFECT: high accuracy of measuring flow rate of a liquid carrier.
