Liquid level gauge sets
Circular design for vessels


SPETECH® liquid gauge glass sets are designed for use with all types of indicating liquid gauges with direct and television reading systems used in pressure vessels, including those with exposure to thermal and chemical loads.

The glass is made from a special-purpose borosilicate glass characterised by a low coefficient of linear expansion and a very high thermal and chemical resistance. This glass is also characterised by very high purity and homogeneity. The superficial stresses, as initially set in into the glass guarantee a high bending strength (and thus, mechanical strength under conditions of internal pressure load), as well as resistance to sudden temperature changes. The glass supplied by SPETECH® complies with the standard dimensions as per DIN 7080, DIN 7081, BS3463, Ö-NormM7353, etc.
