MULTIPARAMETER DEVICE FOR MEASURING BY OPTICAL MEANS THE FILLING LEVEL OF TANKS AND RESERVOIRS OF LIQUIDS AND LIQUEFIED PRODUCTS, THE INDEX OF REFRACTION, AND FOR IMAGE ANALYSIS, WITHOUT MOVING PARTS

摘要

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.

1. A multiparameter device consisting of a measuring device essentially formed by a light guide, having arranged at its ends a light emitting source, an image projector and a photodetector/light and image sensor receptor coupled to an image processor and specific register; wherein the light guide abuts the light derived from a light beam, travelling its interior, not allowing external interferences and that may be composed of a bar or rod of a material transparent to the light used, and that may be image transmitting optic fiber, or the like, involved by layers of index of refraction material so that total internal reflection (RIT) occurs; involved by reflective coatings, with an index of refraction surface layer smaller than the core; wherein the light guide may have various lengths and straight formats, “U,” “S,” and “zig-zag” formats, as well as its straight section, which can vary in the geometric shape required for the material used; with this rod, light guide having inflection points of defined light obstruction, arranged along the light guide length in strategic positions to their function with varying amounts of inflection points with different light obstruction areas and location or having a gradual variation of the index of refraction throughout its structure.
