ABSTRACT:
An airflow metering device, including a conventional airflow sensing device signally connected to a signal processor is shown, having an input flow signal correlatable to a magnitude of mass air flowing past the airflow sensing device. The signal processor is operable to determine a flow correction factor based upon a direction and magnitude of the mass air flowing past the airflow sensing device. The output of the airflow metering device is an accurate measure of airflow, and comprises the input flow signal of the airflow sensing device adjusted by the flow correction factor determined by the signal processor.
