The device has a framework, storage tank, doser and distributor nozzles (2), which are arranged at a distance from each other at a distributor rod. A spray fan (3) ejected from the distributor nozzles is directly illuminated by light sources such as LEDs (4), which are arranged at the distributor nozzles. A sensor unit receives light rays reflected from the spray fan, and is attached to the light sources. |
