Jerguson Large Chamber Gages are designed to give an accurate liquid level reading of liquids that have a tendency to surge or boil.  These gages are highly effective in:

1.  reducing the boiling effects of entrained gas being released under low pressure,

2.  eliminating apparent level fluctuations that occur in standard gages (with small chambers) when boiling / flashing vapors try to rise to the surface, and

3. applications where the operating temperature is below freezing and high ambient temperatures cause the temperature of the fluid in the gage to exceed the boiling point of the liquid.  In applications where the operating temperature is below freezing the gage must be equipped with non-frost extensions.

 Jerguson Large Chamber Gages are available in reflex or transparent design.  The liquid chamber is constructed of heavy tubing, carefully slotted and machined to provide plane seats for the gaskets and glass assemblies.  Covers are steel secured with specially designed steel bolts.

Series L10 Pressure-Temp Ratings

TEST PRESSURE: All gages are hydrostatically tested by Jerguson prior to shipment @ 1 -1/2 times the design pressure rating at 100°F (38°C).
