About us

Visilume Ltd

Visilume supplies a wide range of sight glasses for viewing the contents and also the level of tanks, vessels or pipelines. Sight glasses allow you to monitor liquid flow either manually or at a distance. Sight glasses can be installed by welding, bolting or clamping into your equipment. Sight glasses are assembled to suit the needs of your specific plant and vary in pressure from high vacuum through atmospheric to high pressures up to 1000 bar. There is a very wide range of applications so there are sight glasses suitable for each application from cryogenic through to furnaces. Sight glasses can be as small as 6mm and as large as 600mm. Site glass surrounds are made of diverse materials to suit your process, these include aluminums, carbon steels, stainless steels, duplex stainless steels and hasteloys. We have a wide range of sight glasses to suit different processes and environments:

* Circular sight glasses for viewing the contents of a tank or pressure vessel. * Metaglas sight windows which have unmatched strength and offer the ultimate solution for operator and process safety. * Glass tube liquid level gauges to view the contents of a tank or pressure vessel. * Rectangular site glass fittings to view the level and contents of a tank or pressure vessel. * Transparent level gauges to view the contents of a pressure vessel. * Sanitary and hygienic equipment. * Water treatment sight window fittings
