WELL OPERATION MONITORING UNIT Russian patent published in 2021 - IPC G01F1/00 G01N9/08 

FIELD: oilfield equipment.

SUBSTANCE: invention relates to oilfield equipment of oil production facilities and can be used for automatic measurement of liquid flow rate during joint collection of oil and gas. Disclosed is an installation for determining the flow rate of a liquid during the joint collection of oil and gas, containing at least one switch 3 of the flow of well products, one outlet pipe of which is connected to the measurement line, and the other to the flow line 19. The measurement line includes means for measuring the flow rate of the gas-liquid mixture and the content free gas in a gas-liquid mixture, which are series-installed flow measurement module 6 and free gas measurement module 7, which includes gas-liquid mixture density sensors 24 installed at different immersion depths, each of which includes a float 26 connected to a rod 27 acting on a strain gauge 28 connected to the measuring unit 29.

EFFECT: creation of a non-separable installation for measuring the flow rate of a liquid during the joint collection of oil and gas, in which no sources of radioactive radiation are used, no correction of readings is required when the properties of the liquid change.
