Borosilicate glass is resistant to almost all known materials due to their high resistance to aqueous solutions of salts, organic substances, halogens (chlorine, bromine) and most acids.
Glass for liquid level indicators are made of thermally tempered borosilicate glass and are used in steam boilers at pressures up to 3.5 MPa (35 kgf / cm2), inclusive. In a special performance indicators borosilicate glass, any can be increased many times!
To indicate the liquid level using special glass. They are installed inside steam boilers and other vessels. Usually it is a flat thermally hardened borosilicate glass. There are also serrated glasses which have a smooth surface and a viewing risks prismatic surface opposite thereto.
Main dimensions glasses are shown in the table.

Glass should be colorless. Allowed a bluish, greenish or yellowish tint glass, if they do not reduce the transmittance of light. (For corrugated glass transmittance is not standardized).
Smooth glass have two equally carefully sanded and polished working surfaces. They are perfectly transparent and applied more broadly in steam boilers with nominal pressure up to 3.5 MP (without extra pads mica) in steam boilers with a pressure of 3.5-12 MPa (with mica gasket), in tanks with petrochemical products with a pressure up to 16 MPa and temperatures up to 100 degrees Celsius.
Fluted glass with one hand carefully sanded and polished. The side of the glass which is in direct contact with the liquid contains deposited at an angle of 90 degrees, risks. Through these windows fluid looks dark area, and fumes - light. Corrugated glass is set in steam boilers with nominal pressure up to 3.5 MPa.
The main forms of such products are round and oval.
There are also heat-resistant borosilicate glass execution that can withstand the temperature drop to 500˚S.
