Boiler Level Gauge Sight Glass

Reflex Gauge Glass Reflex level gauge glass is made from High Borosilicate, They are used in level gauge in boiler for water position. Reflex type one side facing the medium chamber is provided with molded grooves set at 90 degree angles. The molding process increases the resistance of the glass grooves to wear; the skin which the glass attains during molding gives it maximum smoothness and hardness.This makes it extremely resistant to the attack of boiler water. It can be used with all media at service conditions up to 4MPa and temperature up to 430 degrees Celsius. It is also named: Reflex Gauge Glasses, Sight glasses, Reflex Glasses,Reflex sight glasses, Spares For level Gauge.

The glass have a groove on one side which contact liquid tank, and in the other two sides fired red glass glaze. According to the optics refraction principle, in the absence of liquid, from the glass facade, can clearly see the red on the groove. When the fluid in the liquid level meter, the refractive index of glass and liquid is the same, the color will not be reflected, can see the white. The sizes are all customized according to clients' requests.
