A mass air flow meter having smaller overall external dimensions than prior devices to facilitate packaging within the engine compartment of a vehicle. Contributing to this smaller size is the use of an "inside-out" venturi in which the inside diameter of the device body is relatively straight and an airfoil shaped body located in the airflow causes the venturi effect. Advantages of this design include high signal to noise ratio, lower manufacturing costs and reduction of bulk.
