ABSTRACT:
An apparatus for measuring the flow rate of intake air into an internal combustion engine is designed such that a conduit mounting ultrasonic sensors 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, such that the device may accurately measure the flow.
