FLOWMETER OF GAS-SATURATED OIL Russian patent published in 1998 - IPC

FIELD: measurement technology, measurement of flow rate of individual components of production of wells in oil industry. SUBSTANCE: flowmeter includes radiation density transducer 1 of mixture placed in pipe-line, unit 2 determining volumetric shares of components of mixture, device 3 processing structural function of process of change of density of mixture, two units 4, 5 determining rate of flow of gas and liquid phases correspondingly, two units 6, 7 setting measurement base of rate of flow of gas and liquid phases correspondingly, three units 8, 9 ,10 determining rate of flow of components of mixture ( gas, fluid and oil ), two units 11, 12 setting density of oil and water correspondingly, unit 13 setting area of cross-section of pipe-line, unit 15 setting pressure of mixture, temperature sensitive element 16 of mixture. EFFECT: enhanced measurement accuracy by provision for invariant of measurement to change of hydrodynamic structure of flow of tested mixture. 2 dwg
