Sight Glasses (Level Indicators)

These gauges give a clear reading on the level of the contents of a tank. They have unbreakable sight tubes and can be supplied in lengths to suit any depth tank.

A variety of tube lengths and fitting options are available

Our range of sight glasses have been designed to comply with BS799 Pt 2 and have been developed for fitting to steel or plastic tanks. The indicator has four components that are usually fitted separately, a gate valve, level gauge, filter and fire valve are incorporated in one unit.

We are also able to manufacture simple, push to read sight gauges for use with any plastic or metal tanks if you require a cheaper alternative and do not require a filter or fire-valve incorporated.

Please contact us with your requirements.
