Abstract
A device for detecting the specific gravity and level of liquid in a container comprising a light source, a photoelectric transducer positioned in light receiving relationship with respect to the light source, a float which has a predetermined specific gravity and is displaced depending upon the change in specific gravity and level of the liquid, and means operatively coupled to the float so as to permit or interrupt the light transmission from the light source to the photoelectric transducer.
