Level Measurement (Sight Glass)

Reflex Type Liquid Level Gauge

Five 90° prismatic serrations are cut into the liquid contact surface of tempered reflex glass to give a prism effect over the whole visual area. Incident light is passed through glass at the liquid phase and is reflected back to the observer at the gaseous phase by the effect of the prism. Therefore, the liquid level can be observed as an interface between the dark liquid phase and the bright gaseous phase.
