MEASURING METHOD OF COMPONENT-BY-COMPONENT FLOW RATE OF GAS-LIQUID MIXTURE Russian patent published in 2014 - IPC G01F1/00 

FIELD: measurement equipment.

SUBSTANCE: measuring method of component-by-component flow rate of gas-liquid mixture involves measurement of volumetric flow rate and transfer of data to a computer. Rotor rotation frequency is maintained at zero differential pressure on it; rotor torque moment values, values of its rotation frequency and viscosity of the mixture are measured; density of the mixture is determined as per the torque moment value and it is compared to one of the two known equations combining density, viscosity and component-by-component fractions of a three-component mixture; measured mixture viscosity coefficient is compared to the other of the two known equations; mass and volumetric component-by-component parts of the mixture are removed by the computer from three independent equations.

EFFECT: simplifying a measuring method of component-by-component flow rate of a gas-liquid mixture at restricted instrument composition of measuring devices; reducing the number of measurement operations requiring simultaneity for more reliable measurement of mass flow rate of medium; measuring flow parameters in one instrument place.
