SYSTEM FOR MEASURING THREE-COMPONENT FLOW Russian patent published in 2008 - IPC G01F1/74 G01F1/56 

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

SUBSTANCE: system contains three coaxially mounted high frequency resonators, each one of which is provided with two mutually-orthogonal inputs-outputs, short-circuited limiting coils, computing and management block, controllable high frequency generator and commutator, input amplifiers, six receiving-transmitting routes. On basis of method of radio-wave high frequency probing of controlled stream in two mutually-orthogonal directions the system measures relative content of its components, and using autocorrelation measurement method the system determines stream speed and on basis of results of these measurements the system calculates component-wise volumetric flow of gas-liquid substance. Mode controller makes it possible to trustworthily determine component-wise flow for substantially transient flow of gas-liquid substance, and method of its mutually-orthogonal probing ensures capability for measurements for fully steady flow of homogeneous substance, when local irregularities of component composition are not present in the stream.

EFFECT: increased efficiency.
