SYSTEM FOR MEASURING FLOW OF GAS-LIQUID FLOW COMPONENTS Russian patent published in 2008 - IPC G01F1/74 G01F1/56 

FIELD: oil extractive industry, possible use for controlling debit of oil wells.

SUBSTANCE: the system contains three coaxially mounted high frequency resonators, each one of which is provided with two mutually-orthogonal inputs-outputs, short-circuited limiting and limiting-separating coils, computing-controlling block, controllable high frequency generator and commutator, input amplifiers, six receiving-transmitting routes. On basis of the method for radio-wave high frequency probing of controlled flow in two mutually-orthogonal directions, relative content of components is measured, by automatic tuning measurement method, flow speed is determined, and on basis of results of these measurements, component-wise volumetric flow is calculated. Mode controller conducts analysis of flow movement mode.

EFFECT: increased precision of measurements in two extreme flow modes: transient and fully steady flows.
