Product Description
Reflex gauge glass is used to read the medium level in the boiler or other tanks. The one side of the glass which is exposed to the medium has a prismatic surface and another side is smooth. The medium level inside the level gauge is indicated as the result of the light refraction principle, since the liquid filled area completely absorbs the rays of light and appears dark, whereas the rays of light are totally reflected in the gas/air filled area which appears bright.
Reflex gauge glass is made from high borosilicte glass. It has many advantages, such as cheap, low maintenance cost, easy level reading and excellent high temperature & pressure resistance. The edge can be polished or frosted.
It can be used with all media at service conditions up to 4MPa and temperature up to 430 °C.
The side facing the medium chamber is provided with molded grooves set at 90°angles. The moulding process increases the resistance
of the glass grooves to wear; the skin which the glass attains during moulding gives it maximum smoothness and hardness. This makes it extremely resistant to the attack of boiler water.
It is used on observe level gauge of boiler for water position. It is also named: Reflex Gauge Glass, Sight glass, Reflex Glasses, Reflex sight glass, Spares For level Gauge.
