Welding Pad GagesGlass-Trac Welding Pad Gages are used when standard tank connections cannot be used or when the liquid has solids in suspension. The NOTES: Welding pad gages to be used on vessels less than 36” in diameter must be special ordered. The welding pad body must be machined to allow proper fit up. When ordering, add WP to gage size number. MISSING IMAGE***************
Large Chamber
Recessed seats are machined into the liquid chamber and gage covers for protection of glass, gasket and cushion. Special bolts are used. Large Chamber Gages are made in lengths for standard flat glasses and multiple section gages are available. When ordering, add LC for large chamber to gage size number and CH for close hook-up.

On externally heated/cooled gages a metal tube is employed to transmit heating or cooling fluid. The tubing starts from an adaptor nut on one valve, passes along a machined groove in the gage body wall and connects to the adaptor nut in the opposite valve. Fluid piped through the tubing serves as the heating or cooling media. Gage bodies (liquid chambers) are made extra long to accommodate the groove and tubing. Most common heating fluids are steam and hot water. To cool gages, methane, propane, freon and ammonia refrigerants are used. The adaptor nut on the gage valves can be fitted with either a ½” NPT Female Tank connections or When ordering Glass-Trac Externally Heated/ Cooled Gages, add HC to the gage size number. FROST PREVENTION EXTENSIONGlass-Trac plastic extensions for flat gage glasses prevent frost from forming in the liquid level view slot in low temperature services. Reflex and Transparent Gages in all pressure ratings can be fitted with plastic extensions. Projecting from the view slot, the clear plastic extensions keeps the liquid level indication clearly visible. Stocked extensions are 1⅝” and 3⅝” in length. If the gage is thickly insulated, longer extensions are available. The extension is held in place by stainless steel clamps fastened to the gage cover. For extra low temperature services, Glass- Trac gages can be made of special metals. Recommended length for Frost Preventive Extensions: 1⅝” extension is standard from 80ºF ambient to 0ºF temperature. Add 1” extension length for each 100º F below 0º F. When ordering, specify length and add FP to gage size number. Drawings:

gage becomes an integral part of the vessel because it is welded right onto the outer wall. Reflex or Transparent glass is used in any of nine standard lengths. Standard covers are 3⅛” wide. 
Glass-Trac Large Chamber Gages are made in a special low pressure series of both Reflex and Transparent Gages. The large diameter chamber makes accurate liquid level readings possible under unusual conditions such as boiling, flashing, or foaming of the liquid. The chamber is manufactured from heavy duty seamless steel pipe with an inside diameter of 2⅛”. Each end of the pipe is closed off with a welded plug which is drilled and tapped for ¾” NPT connections. For close hook-ups, ¾” NPT side connections are made and ends may be drilled, tapped and plugged for cleaning as required.
Glass-Trac Externally Heated/Cooled Gages may be either low Pressure or Mid Pressure or Mid Pressure, Reflex or Transparent and have ½” or
