Series W20 & W300L Weld Pad™ Liquid Level Gages
Features
Applied directly to tank
User must determine if acceptable for ASME Sec. VIII
Recessed Gasket Seat in Chamber and Cover
Tempered Borosilicate Glass conforming to BS3463, JIS B8211, & DIN 7081
Wetted parts conforming to NACE MR0175 & MR0103 available
All parts listed in ASTM & ASME B31 .3
Standard Weld Pad Gages
Available in both reflex and transparent types. Generally used for non-critical applications. When using standard weld pad liquid level gages, the tank must be relieved of pressure and drained to service the gage. Seal pots are a typical application. This type of gage is not used on critical process equipment because you cannot perform maintenance or replace a gage without shutting down the entire process.
Isolable Weld Pad Gages
Jerguson Isolable Weld Pad Gages follow the general design of standard Jerguson weld pad gages but other the additional advantages of integral valves. Because the gage can be isolated from the vessel by the valves, gaskets or glass can be replaced without lowering the level of liquid below the gage inlet or relieving pressure from the vessel. Isolable gages are installed by matching the valve inlets with holes drilled in the vessel and making a 100% fillet weld between the vessel wall and the valve inlets. The gage chamber is tack welded to the vessel.
