Measurement of the volume flow, especially in dusty applications. Easy installation on existing ducts, no Venturi or similar conversions are required. Can be used in environments with low dust loads or in harsh conditions with e. g. high dust loads.
AirFlow P is the perfect measuring device for volumetric flow measurement at positions where differential pressure measurements can not be used due to excessive dust loading or where duct conversions are not possible or desirable.

FUNCTIONS
Via two antennas that protrude into the air duct, the AirFlow P is able to perform a very accurate speed measurement.
If the area of the duct is stored on the evaluation unit, the AirFlow P system supplies a signal at the analogue output cubic metres per hour (v x A).
By using the latest technologies, it is possible to measure a volume flow with the AirFlow P in clean gas ducts with a dust loading of only a few mg/m³.
It is also possible to use the AirFlow P as a pure speed measuring device, e. g. in order to keep the actual material velocity constant.
