FIELD: measurement technology. SUBSTANCE: invention is aimed at measurement of mass flow rate of air injected into internal combustion engine. Device includes holder placed sidewise to flow and temperature-sensitive element anchored in holder. Obstacle in the form of edge of protrusion to create stable stalling behind obstacle is located in zone of inlet hole of measurement conduit made in holder above temperature-sensitive element in path of pulsating air flow. EFFECT: increased measurement accuracy thanks to reduced noise component in signal of temperature- sensitive element. 5 cl, 2 dwg
