ABSTRACT:
A Karman type air flow sensor element is disposed within a duct slidably mounted between members defining an annular space. The annular space causes the intake air to increase its velocity as it approaches the inner periphery of the annular space thus creating a pressure differential zone. By moving the duct so that the inlet and outlet are exposed to different high and low pressures respectively the pressure differential across said the inlet and outlet of the duct can be controlled to vary the fraction of the total intake air inducted therethrough.
