One embodiment provides a flow meter including an airfoil movably secured
in the airflow path of a fan in an electronic system. The airfoil is
configured to generate a lift component in response to the airflow. A
sensor engages the airfoil and generates a signal in relation to the
movement of the airfoil. Airflow parameters such as volumetric airflow
rate and turbulence may be identified by an analysis of the movement of
the airfoil.
