SYSTEM OF MEASUREMENT OF MASS FLOW OF THREE-COMPONENT GAS-LIQUID FLOW COMPONENTS OF OIL WELLS Russian patent published in 2008 - IPC G01F1/74 G01N22/00 G01F1/86 E21B47/10 

FIELD: physics.

SUBSTANCE: invention may be used for monitoring of oil wells debit. System contains two high-frequency resonators that are coaxially installed on dielectric tube and each of them represents short-circuited zigzag conductor with two mutually-orthogonal inputs-outputs and limiting and limiting-dividing coils, Coriolis acceleration flow meter with transducers of flow and density, pressure sensor and temperature sensor, computer-control unit, controlled high-frequency generator and switchboard, controller of stream flow modes, the first and the second controllers of Coriolis flow meter calibrations, two input amplifiers, four transmitting routes and eight dividing condensers. On the basis of method of radio wave high-frequency sensing of flow in two mutually orthogonal directions relative volumetrical content of its components is measured, by means of method of autocorrelated velocity change flow velocity is determined and with the help of Coriolis flow meter and calibration controllers mass flow and density of controlled medium is measured.

EFFECT: increase of flow rate measurement accuracy.
