FLOW RATE MEASURING SYSTEM OF GAS-LIQUID BOREHOLE FLOW AGENTS Russian patent published in 2008 - IPC G01F1/74 G01N22/00 G01F1/86 E21B47/10 

FIELD: physics.

SUBSTANCE: system contains two high-frequency resonators mounted on dielectric pipe, each of which represents short-circuited meander lined conductor with two mutually orthogonal inputs-outputs, constraint and constraint-dividing coils, Coriolis acceleration flowmeter with electronic flow and density transducers, pressure probe, computing controller, controlled high-frequency alternator and switchboard, flow pattern controller, first and second calibration controllers of Coriolis acceleration flowmeter, two input amplifiers, four transmitting paths and eight blocking capacitors. 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 selection of stored array calibration of Coriolis acceleration flowmeter according to specified pattern.

EFFECT: invention raises accuracy of measurement even at essentially unsteady current of a stream.
