METHOD AND DEVICE FOR MEASUREMENT OF GAS-LIQUID MIXTURE AND ITS COMPONENTS FLOW RATE Russian patent published in 2010 - IPC G01F3/38 G01F15/08 

FIELD: measurement equipment.

SUBSTANCE: invention is related to the field of gas-liquid flow rate measurement. Capacity of calibrated chamber is measured under conditions of plant operation in working mode of well. Flow rate of gas-liquid mixture is measured. Besides capacity of calibrated chamber and flow rate of gas-liquid mixture are measured simultaneously in each cycle of calibrated chamber emptying or in specified number of cycles with the help of capacity carrier, for instance tube-piston unit. Device for measurement of gas-liquid mixture flow rate comprises horizontal separator, measuring calibrating chamber arranged in the form of vertical accumulating reservoir, and also pipeline that drains gas-liquid mixture. Separator and calibrating chamber are joined according to principle of communicating vessels by pipelines of gas-liquid and gas line. Pipeline that drains gas-liquid mixture is equipped with carrier of capacity, for instance tube-piston unit.

EFFECT: improved accuracy of flow rate measurement.
