DEVICE FOR MEASURING PARAMETERS OF GAS-LIQUID MIXTURE OBTAINED FROM OIL WELLS Russian patent published in 2017 - IPC G01N9/26 G01F1/86 

FIELD: measuring equipment.

SUBSTANCE: device comprises a measuring column with a vertical branch equipped with the first pressure difference sensor and absolute pressure and measured liquid temperature sensors, and a branch of the measuring column comprising a section of a calibrated pipeline of length L₁ of the maller diameter D₁ and a section of a calibrated pipeline of length L₂ with an abrupt enlargement of its diameter D₂ in the outlet nozzle, equipped with the second pressure difference sensor. The branch of the measuring column in the section of the calibrated pipeline of length L₁ is equipped with the third pressure difference sensor, and the vertical branch of the measuring column of diameter D is equipped with the fourth pressure difference sensor. In addition, on the vertical branch of the measuring column a vessel with "reference" liquid which maintains a constant level of heights of the "reference" liquid columns h₁ and h₂ in pulse tubes is installed, and at the input of the vertical branch of the measuring column a flow linearization grid is installed. In this case, all measuring sensors are connected to a recording unit with a program for determining the density, flow rate, viscosity, amount of water mass, oil, gas of the measured gas-liquid mixture according to the attached formulas.

EFFECT: increased accuracy of measuring the density of the measured gas-liquid mixture and expanded functionality of the device.
