FLOW RATE MEASURING SYSTEM OF TERNARY GAS-LIQUID FLOW AGENTS Russian patent published in 2008 - IPC G01F1/74 G01N22/00 G01F1/86 

FIELD: physics.

SUBSTANCE: system contains two high-frequency resonators coaxially mounted on dielectric pipe, each of which represents short-circuited zig-zag rectangular cross section conductor with two mutually orthogonal inputs-outputs and constraint and constraint-dividing coils. Coriolis acceleration flowmeter with electronic flow and density transducers, pressure probe and temperature sensor, computing controller, controlled high-frequency alternator and switchboard, flow pattern controller, the first and the second calibration controllers of Coriolis acceleration flowmeter, two input amplifiers, four transmitting paths. Using radio high-frequency flow probing method in two mutually orthogonal directions the volume content of flow agents is measured. While autocorrelation flow velocity variation method combined with Coriolis acceleration flowmeter and calibration controllers is used to measure flow rate and density of controlled medium. Calibration controllers assuming flow pattern controller data allow for selected calibration of Coriolis acceleration flowmeter according to specified pattern.

EFFECT: invention improves measurement accuracy at unstable flow.
