FLOW-RATE MEASUREMENT METHOD Russian patent published in 2000 - IPC

Abstract RU 2152593 C1

FIELD: measurement of mass flow rate of medium. SUBSTANCE: method is used for measuring of mass flow rate of variable-compound medium by means of thermoconvective transducer which includes heater and two thermoresistors positioned on external surface of tube. Time τ_g of thermal mark transfer between heater and fixed (control) section time τ_k of mark transfer along control section and measured. Density of measured medium is judged by difference (τ_g•τ_k). Value τ_g serves for calculation of volume flow rate. EFFECT: enhanced accuracy of measurement. 3 dwg
