Abstract (en)
An apparatus for measuring the flow rate of intake air into an internal combustion engine is designed such that conduit-mounted ultrasonic transducers (4) can respond quickly to changes in the intake air temperature. In this manner, any modulation of the emitted ultrasonic energy due to temperature effects can be eliminated, so that the device may accurately measure the flow. The detector portion (2) carrying the sensors (4) is mounted within a casing (1) (e. g. the air filter casing) by a partition wall (9) which is downstream of the sensors (4).
