6.3.2 Calculating the actual air flow
• After measuring the static pressure, read the settings of the four JetCone adjustment pins to find the mean value of the
pins.
• Locate the diagram inside the openable perforated faceplate, (also see diagrams in 6.3.5), and use the static nozzle
pressure and the mean value of the pins to find the current airflow.
6.3.3 Changing the actual air flow
• Measure the static nozzle pressure.
• Locate the air pressure/airflow diagram inside the openable perforated faceplate. (Also see diagrams in 6.3.5).
• Find the mean value of the 4 pins to reach the desired airflow, in the diagram. Use the static nozzle pressure and the
desired airflow to find the mean value of the 4 pins.
• Adjust the 4 pins in the beam, so the mean value of the pins will correspond with the mean value found in the diagram.
• See example in 6.1.2 / 6.1.3 .
