Measurement of the Component-by-Component Flow Rate of a Gas-Liquid Medium by the Thermal Method

The issue of the measurement of a gas-liquid medium by the mass component-by-component flow rate is examined. A thermal method is proposed for measurement of the component-by-component flow rate of a gas-liquid medium that is flowing past on the channel, with uniformly distributed cross-sectional heat energy. Components of the medium with different heat capacity receive pulsed thermal charges different in value, recorded by heat flow sensors. The type and amount of the components is determined from the absorbed heat energy. Complex equipment is not required to implement this thermal method. Heat capacities are measured with minimum distortions of the transmission of heat flow by means of the newest sensors of a gradient type, with a small time constant and high sensitivity.
