The airflow sensor is used for measuring the airflow of the fan.
The method is based on pressure differential. The pressure is
measured at the specific point in the inlet cone and the reference
pressure is measured upstream of the inlet cone. The air flow
sensor is factory mounted in the inlet cone.
