MEASURING INSTRUMENT OF CONTENT OF DISPERSE PHASE IN THE GAS FLOW Russian patent published in 2018 - IPC G01N25/56 G01F13/00 G01N1/20 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the field of quality control of the preparation of natural and associated petroleum gases to transport, and also to the field of quality control of liquids transported through pipelines in the oil and gas industry and can be used by fuel and energy, chemical, petrochemical and oil and gas refineries. Measuring instrument of content of dispersion phase in gas flow includes a sampling probe, a separator equipped with an element filter and a batch meter for liquid separated from gas, a gas flow-regulation valve, an inhibitor tank and an inhibitor delivery valve to the gas flow-regulation valve, a cartridge filter for mechanical impurities trapping from the gas, and additionally comprises a device for automatic moving of the sampling probe along the cross-section of the test pipeline, a pressure-differential transducer between the sampling line and the testing gas-dispersed flow to be sampled for isokinetic sampling due to the automatic maintenance of the valve-regulator, installed at the output of the sampling line, the zero value of the pressure difference between the sampling line and the testing gas-dispersed flow, the means for thermostating, the mass flow meter for taking the amount of the separated liquid in the measuring tank into account, containing the liquid level gage.

EFFECT: accuracy increase in measurement of the content of the dispersed phase in the flow.
