Abstract
System for detecting the level using the photovoltaic principle. It is based on the detection of the angle which is formed by a float which follows the surface of the liquid, with the location of a servocontrolled photovoltaic sensor housed in an end position within range of the liquid. The level-measuring process is implemented by a calculation device which converts the value of the angle into the height of the liquid or level.
