What is a sight glass
A sight glass is a type of level sensor which is used to check the level of liquids in steam boilers or a liquid container. The most common method of checking liquid level is to use a sight glass.
Therefore, it is also termed gauge glass. The liquid level can be observed through the sight glass, which is mounted on the tank. Graduations are marked on the sight glass so that the level can be measured.
How does sight glass work
A basic sight glass for a tank in which the liquid level in the sight glass refers to the liquid level in the tank. The liquid value in the tank rises and falls in synch with the level in the sight glass. Thus, the level of liquid in the tank is monitored by checking the level in the sight glass.
A high-pressure sight glass is used to make measurements by reading the location of the liquid level on the calibrated scale. In high-pressure tanks, this kind of sight glass is utilized with the proper safety measures. The interior diameter of the glass tube must be small, and the wall must be thick.
