Ray : Retro Reflective Optic Level Switch

Measuring Principle

An infrared emitter sends chopped light into the Prism. When in air the light undergoes total internal reflection and is sensed by the Photo-detector.

When the Prism is covered by the liquid, the light gets dispersed and so is not detected. This change is processed to signal an alarm.
