Tank Level Gauges & Indicators

Tank level gauges with sight glasses are used for the continuous indication of the liquid level within a tank or vessel. They usually consist of a top and bottom fitting with isolation and drain cocks fitted. They are installed to the outside of the tank or vessel with tubular glass or perspex between them.

Johnson valves offer these gauges for different duties including marine, boiler house and oil tank indication with glass cut to your requirements. Protectors and guards can also be made to your requirements.
