measurement technology, specifically, determination of component by component flow rate of three-component gas and liquid flow of oil well. SUBSTANCE: main and additional identical to it electrical fields are formed in gas and liquid flow with the aid of setting and pickup coils placed in analyzed medium. Additional electric field is arranged along direction of flow in front of main electric field. Lines of force of both electric fields are directed perpendicular to flow. Dependence of electrical conductance of flow on time is measured by way of integration of instantaneous values of currents fed to pickup coil of main electric field. Then fractional content of components of flow is found by measured value of conductance in accordance with experimental dependence of electrical conductance of medium on time and content of components of liquid and gas in it. Later additional electric field is removed and dependence of electrical conductance on time is determined during same time interval and difference between
