Jerguson Large Chamber Liquid Level Gages are designed to give an accurate liquid level reading of liquids that have a tendency to surge or boil.  These glass 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.
