What is Sight Glass Level Gauge?


#1

The sight glass consists of a strengthened glass tube, attached to the container as shown in Figure, through which the fluid level in the container can easily be observed by the operator.

Monitoring the level from a distance, is facilitated when a magnetic float inside the tube, is allowed to rise and fall with the liquid level, causing metallic flags (or louvers) to flip and expose a different colour, indicating the level.
