Large Chamber Flat

Large Chamber Flat Glass Gages

Large Chamber Flat Glass Gages for turbulent surface or extremely transparent liquids.

Combining high pressure covers and a large cylindrical chamber, these gages can improve accuracy in determining turbulent vessel liquids levels. In addition to simulating the function of a stilling well and providing a liquid column approximately four times the diameter of standard gages, large chamber gages can provide end connections up to 2" NPTF that can accommodate various instrumentation.

All materials in large chamber gages conform to AISI or ASTM specifications. RLC gages can achieve pressures to 2400 psig (16540 kPa) @ 100°F (38°C) and TLC gages can achieve pressures to 1580 psig (10889 kPa) @ 100°F (38°) for all glass sizes.

Penberthy does not recommend large chamber gages for steam/water applications.

Weld Pad Flat Glass Gages

Weld Pad Flat Glass Gages for direct mounting to vessel wall.

For applications involving high vibration, highly fiscous liquids or liquids with considerable amounts of solids, Penberthy offers end users a flat or radius weld pad gage. Because there are no nipples through which the process liquid enters the gage, clogging potential is eliminated.

When welding the gage to a vessel, it is extremely important to take proper precautions to prevent warpage of the chamber. Penberthy strongly recommends the use of an optional steel spacer for welding.

After welding, it is important to check the flatness of all glass seating surfaces as described in Penberthy’s Installation, Operation, and Maintenance manual.

All materials in weld pad gages conform to AISI or ASTM specifications. RMW and TMW gages can achieve pressures to 2000 psig (13783 kPa) @ 100°F (38°C) - when manufactured with size 1 glass.

Ultra-High Pressure Flat Glass Gages

Ultra-high Pressure Flat Glass Gages for extraordinary pressure and vapor requirements

The method of clamping and sealing the glass differs from other gages in that the glass does not experience stress concentrations imposed by bolting. The glass becomes a floating member between two solidly bolted blocks of rigid plate.

The pressure activated seal principle provides a self adjusting means of maintaining a tight joint between glass and liquid chamber. The gasket system compensates for machining variations.

Because glass can take a tremendous amount of evenly loaded compression, the gage can withstand extremely demanding pressure requirements.

All materials in TU gages conform to AISI or ASTM specifications. TU gages can achieve pressures to 6000 psig (41369 kPa) @ 250°F (121°C). Pressure rating is not glass size dependent. A higher temperature rating 400°F (204°C) @ 6000 psig (41369 kPa) can be achieved by using Viton®. Teflon® can achieve 500°F (260°C) @ 6000 psig (41369 kPa).
