Air outlets
Every duct inlet and outlet should only contain the volumetric flow that, according to its calculations, is the basic requirement for a system that works efficiently. It must therefore be possible to measure according to EN 16211 the volumetric flow in a reliable way. Particularly large vane anemometers are suitable for measuring the volumetric flows or air velocity at duct outlets as per EN 16211, as these integrate the velocity of the flow in the duct over a larger area, thereby determining disturbance from the air grille (loop method).
