2.2.1 Measure the static nozzle pressure.
– To measure the air pressure, a manometer, analog or digital (such as the Lindab
PC410) will be needed.
– Insert the measuring tube onto the specialized measuring nozzle
– Read off the static nozzle pressure from the manometer
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, and use the static nozzle
pressure and the mean value of the pins to find the current airflow.
