FIELD: instrumentation.
SUBSTANCE: invention relates to instrument making, namely to devices for measuring mass flow of liquid carriers. Method of measuring liquid carrier flow rate using Coriolis effect, according to which inside the housing there is a rotor assembly with a central shaft of rotation and multiple 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 horizontal shaft, which is mounted in rotary bearings installed in closed housing. Housing encloses the rotor assembly with a minimum gap and has two holes in the plane of the radial channels along the horizontal line passing through the axis of rotation. Flexible pipelines are connected to the holes. Fluid carrier flow rate is measured by dynamometer loaded with housing and rotor assembly. Radial channels are made with a rectangular cross-section, on the outer circumference of the rotor assembly and on the surface of the central cavity of the rotor assembly, the walls of adjacent radial channels, located parallel to the axis of rotation, are aligned with each other, shape and size of holes in closed housing for supply and discharge of liquid carrier are selected to be identical with cross section of radial channels on outer circumference of rotor assembly.
EFFECT: high accuracy of measuring mass flow rate of a liquid carrier.
