FIELD: measurement of flow rate of air sucked by internal combustion engine. SUBSTANCE: proposed device is secured on suction pipe line receiving the measuring part of device; this part has measuring channel where flow rate metering unit is located. Measuring part is turned relative to direction of flow in suction pipe line through angle of 2 to 10 deg. EFFECT: reduced spread in characteristics due to unstable conditions of flow at measuring part. 3 cl, 1 dwg
