FLOW RATE MEASURING SYSTEM OF TERNARY BOREHOLE GAS-LIQUID 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, the first and the 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 is used to measure flow velocity, and Coriolis acceleration flowmeter and calibration controllers are used to measure flow rate and density of controlled medium.

EFFECT: selection of reliable calibration allows for precise measurements of flow rate and density of medium even for considerably unstable nonuniform gas-liquid flow.
