MISURA DELLA PORTATA VOLUMETRICA
Misura della portata volumetrica, soprattutto in applicazioni polverose. Facile installazione su condotti esistenti, non sono necessarie conversioni Venturi o simili. Può essere utilizzato in ambienti con bassi carichi di polvere o in condizioni difficili con, ad esempio, alte temperature o carichi di polvere elevati.
AirFlow P è il dispositivo di misurazione perfetto per la misurazione della portata volumetrica in posizioni in cui le misurazioni della pressione differenziale non possono essere utilizzate a causa di un eccessivo carico di polvere o dove le conversioni dei condotti non sono possibili o desiderabili.
Disponibile nuova versione per alte temperature, adatta per applicazioni fino a 800°C

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.
