The recording of the sensor data and the calculation of the flow values are carried out the easiest way by our efficient flow computer.
Suction operating mode is the preferable operating mode for these nozzles, since the atmospheric density on the inlet is very constant and disturbances on the outlet side cannot pass the constriction.
In order to ensure that an critical nozzle works optimally, geometric conditions have to be met. Free and undisturbed incoming flow is observed at high-capacity conditions at the inlet section of the nozzle: no barrier is allowed to get closer to the nozzle axis and the inlet level than 5 times the nozzle diameter. In general, the inlet diameter should be at least four times wider than the throat diameter of the nozzle, so that the flow rate in front of the nozzle remains low.
