FLOW METER AND AIRFLOW MEASUREMENT USING AN AIRFOIL

摘要

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.
