Clear level sight glass is mounted with plain glass on the front as well as the back, the liquid column being between these two glasses.
Checking the level occurs by viewing the surface of the liquid, which assumes a concave shape similar to a small bubble in cases of transparent fluids such as water., for example. This concave shape on the surface of the liquid is the only indication of the position of the level..
This sight glass is recommended for saturated steam up to 85 bar*. Its panes are protected by mica sheets to resist the chemicals generated by the steam alkalinity at high pressures.
It can be supplied with light sources for better level visualization.
*For pressures up to 180 20 bar, contact us, getting into contact here on the website!
