FIELD: measurement of flow rate of multiphase streams with the aid of thermal flowmeters. SUBSTANCE: temperature difference is measured in two sections of measurement length between which fixed quantity of heat is fed, overheating of temperature-sensitive resistors during operation under mode of hot-wire anemometer is additionally measured in the course of fixed time interval as well as time during which each temperature-sensitive resistor has overheating value with in bounds of range characteristic of each substance included in stream and ratio of this to fixed time interval is taken into account for determination of flow rate. EFFECT: improved authenticity of method. 3 dwg
