FIELD: oil deposit automated separator system designed for measurement of crude oil production including mixture of oil, gas and water. SUBSTANCE: automated system uses Coriolis flowmeter which serves as a mass flowmeter and densimeter in combination with water-cutting monitor for calculation of volume flow rates and density of materials discharged from testing separator in combined two-phase flow of product. Density value of oil phase is corrected to obviate effect of water content in it and divided by index of mass flow rate to obtain real value for oil. System operation is controlled by automated controlled which uses system of gas shell for prevention of low pressure due to gas evolving from fluids inside testing separator. EFFECT: full automation of well testing and excluded errors in volumetric measurements occurring due to release of natural gas dissolved in oil at low pressure. 11 cl, 2 dwg
