Abstract
A device for monitoring a urea solution in a tank of a motor vehicle tank includes a light source capable of emitting a light beam, a photodetector capable of detecting a portion of a light beam emitted by the light source, and a part made of a material allowing the propagation of a light beam emitted by the light source. The part includes a surface intended to be in contact with the urea solution. The light source, the photodetector, and the part are arranged in such a way that a light beam emitted by the light source is propagated by the surface of the part, by refraction, toward the photodetector. A tank including such a monitoring device is provided. A process for monitoring a urea solution in a tank of a motor vehicle is also provided.
