Product Description

level gauge glass(boiler sight glass)
A sight glass or water gauge is a transparent tube through which the operator of a tank or boiler can observe the level of liquid contained within.

gauge glass, made from high borosilicate 3.3 glass, has good performances:

High Hydrolytic Resistance
High Chemical Resistance
High Resistance to Thermal Shock


A level / reflex gauge is more complex in construction but can give a clearer distinction between gas (steam) and liquid (water). Instead of containing the media in a glass tube, the gauge consists of a vertically oriented slotted metal body with a strong glass plate mounted on the open side of the slot facing the operator. The rear of the glass, in contact with the media, has grooves moulded into its surface, running vertically. The grooves form a zig-zag pattern with 90° angles. Incident light entering the glass is refracted at the rear surface in contact with the media. In the region that is contact with the gas, most of the light is reflected from the surface of one groove to the next and back towards the operator, appearing silvery white. In the region that is in contact with the liquid, most of the light is refracted into the liquid causing this region to appear almost black to the operator.
