Bingo 3 is a general purpose liquid detector. It provides an indication of the presence or absence of liquid and is ideal for monitoring critical heights on any liquid tank, including gasoline, jet fuel or diesel. It uses infrared refraction differences to reliably and immediately indicate whether the sensor is immersed in liquid. It is mountable on any wall of an enclosure. When properly mounted, the LED portion of the sensor is outside of the tank and only the optical facets penetrate into the tank.
