FLOW-RATE MEASUREMENT METHOD

摘要

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 taug of thermal mark transfer between heater and fixed (control) section time tauk of mark transfer along control section and measured. Density of measured medium is judged by difference (taug.tauk). Value taug serves for calculation of volume flow rate. EFFECT: enhanced accuracy of measurement. 3 dwg
