FIELD: measurement equipment. ^ SUBSTANCE: system includes two high-frequency resonators in the form of short-circuited conductors with two mutually square inputs-outputs, mounted on dielectric tube, two limiting coils and limiting separation coil, Coriolis flow metre with electronic flow rate and density converters, pressure sensor, computation and control unit, controlled high-frequency generator and switch, flow mode controllers, first and second coriolis flow metre gauging controllers, two input amplifiers, four transmission paths and eight separation condensers. By the method of high-frequency radio wave probing, relative volume component content is measured in two orthogonal directions; flow velocity is measured by autocorrelation measurement method; and mass flow rate and density of examined medium are measured with the help of coriolis flow metre and gauging controllers. Gauging controllers select coriolis flow metre gauge relevant to the flow mode. ^ EFFECT: enhanced measurement accuracy even for greatly instable flow. ^ 5 dwg |
