2.2.2 Calculating the airflow
– After measuring the static nozzle pressure, read the setting of the four pins in the
corners to find the mean value of the pins.
– Locate the diagram on the faceplate or see diagram 1-2, and use the static nozzle
pressure and the mean value of the pins to find the current airflow.
