ABSTRACT:
Apparatus for obtaining the mass flow rate of engine aspirated air. An ultrasonic transducer measures the density of atmospheric air, while coincidentally measuring the velocity of air within a venturi of an engine air induction tube. The two individual measurements produce a single electric output signal proportional to the mass flow rate of air.
