Device for determining the volumetric flow of a radial fan with at least one inlet nozzle defining an admission aperture and preconnected to a fan impeller. It is proposed that at least one pressure measuring device (24) be arranged at least partially (29) at a measuring point (23) in the area of the inlet nozzle (10) and at the same time in the area of the through-flow aperture (11), the measuring point (23) or that part (29) of the pressure measuring device (24) located there being advantageously located in the area of the inside circumference of the inlet nozzle (10). <IMAGE> |
