Apparatus and method for automatically detecting at least one fluorescent contained in a functional fluid and / or light-absorbing indicator

摘要

The present invention relates to a method and a device for automatically detecting at least one fluorescent contained in a liquid fuel and / or light-absorbing indicator during the dumping of the fuel into a machine, in particular a prime mover of a vehicle. According to the invention, the detection by- Irradiation of the fuel to be detected during the filling process with at least one light source (3) in a measuring section (2),- Collection of light (14), comprising the functional fluid in the measuring section (2), and / or of the indicator contained in this effect is based on the basis of a fluorescence by means of a light reception device (5), wherein the intensity of the light of the at least one indicator or its concentration is influenced,- Generating at least one the intensity of the light striking the light reception device follows the contour of the measurement signal (8, 9),- Evaluation of the at least one measurement signal (8, 9) in an evaluation unit (10) and comparison with stored values.
