SIGHT GLASS/WELD PAD SIGHT GLASS

 Available in Circular and Rectangular Pad types. 

Weld pad sight glass, also known as weld pad liquid level gauge or weld pad level indicator, is a kind of liquid level gauge that is directly welded in a way of tack welding or full welding to the container walls or in the tanks.

Weld pad level gauges are available in both reflex and transparent gauge glass configurations. It is generally used for pressure vessels, vacuum vessels, tanks, reactors, filters, boiling beds and other types of closed containers or non-critical process containers.

Tanks must be relieved of pressure and drained to install and service the gauge.

Weld pad level gauges are widely used for high vibration, highly viscous liquids, or liquids with considerable amounts of solids generated in the industrial production process of petroleum, chemical, chemical fiber, pharmaceutical, food, etc.
