A new multiparameter device for measuring by optical means, the level of filling of tanks and reservoirs for liquids and liquefied products, index of refraction and image analysis, without moving parts, which is more specifically intended, but without restrictions of application, for the measuring the level of a liquid in a reservoir, besides being able to make possible the distinction and detection of the type of liquid included in this reservoir, by measuring the index of refraction and image analysis of these liquids, performing this task in a simple, practical and efficient manner through a specific configuration utilizing optical and electronic means, without use of moving parts, what allows that the same may be used for numerous applications between them, for the fuel quality control, the fuel identification, the measuring of the index of refraction, flow measurement, color measurement, temperature measurement and pressure measurement, inter alia, and more specifically for application in the automotive and associated industries.
