AGENT-SPECIFIC FLOW RATE MEASURING SYSTEM OF GAS-LIQUID BOREHOLE 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 conductor with two mutually orthogonal inputs-outputs and 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. Selecting of reliable calibration corresponding to actual condition of controlled flow allows for precise measurement of flow rate and density of medium even for considerably unstable nonuniform gas-liquid flow. Collection of gas-liquid flow pattern, velocity, flow rate, density and pressure data received with computing controller provides accurate and reliable calculation of agent-specific flow rate of controlled medium and data transmission to outer systems.

EFFECT: improved measurement accuracy.
