Sound-damped volumetric flow controller model Piano / Piano-S Description The shorter design compared with conventional pressure reducing boxes simplifies mounting in constricted places and allows space to be saved due to the low overall height. Due to the smaller dimensions, installation has been radically simplified. The sound-damped volumetric flow controller type Piano with rectangular connection can be connected to rectangular ducts to DIN 24190 or to spiral ducts to DIN 24145 via a transition piece. This allows the sound-damped volumetric flow controller type Piano to be used for different...

Sound-damped volumetric flow controller model Piano / Piano-S Technical data Static minimum pressure difference Volumetric flow range NW Attention, the following specifications are important for the programming of the volumetric flow controllers: - this table merely specifies the complete measuring range of the controller (volumetric flow range), calibration curve 12 m/s - If the customer absolutely wants a calibration curve, it must be specified! - When the air volume drops below the Vmin shown in the chart, the correct functioning of the volumetric flow controller is no longer guaranteed! -...
