Call for Availability

Jergusons Series 20 glass liquid level gages are available in transparent and reflex glass for clean and dirty liquid level applications.

Jerguson's Series 20 glass liquid level gage is available in both transparent and reflex glass versions. The transparent glass style allows for dark or dirty water to be measured accurately, while the reflex glass uses glass prisms to make reading the levels easier for clear-type fluids like gasoline.

Their one-piece chamber is encased in carbon steel and shrouded to give the glass edges more protection. Gage sections are available in nine standard glass sizes. Longer models can be constructed with multiple vision slots in a continuous solid bar chamber.
