PROCESS OF DETERMINATION OF MEAN CONCENTRATION OF PHASES OF TWO-PHASE FLOW Russian patent published in 1997 - IPC

FIELD: measurement technology, check of parameters of two-phase gas-and-liquid flows in power engineering and other branches of industry. SUBSTANCE: proposed process includes measurement of electric signals in n points of passage with the use of electrodes, selection of maximum signal as reference one, registration of deviation of signals on electrodes $$$ from reference one, determination of number of electrically closed electrodes $$$, determination of concentration of vapor phase by formula $$$ and determination of liquid phase by means of relation $$$, where $$$ is number of combinations of pairs of electrically closed electrodes. Transducer for realization of process has n electrodes uniformly positioned in dielectric housing with drop-shaped profile. EFFECT: increased authenticity of measurement of concentration of phases under unsteadily conditions thanks to decreased time of measurement. 3 dwg
