Jerguson® Armored Level Gages

reflex(ret) Jerguson® Reflex Level Gages are ideal for clean total level indication applications for refining, petrochemical and general use applications. The reflex prisms are molded and polished to provide a crisp black-silver bi-color indication of the fluid level. As light passes into the reflex glass, if there is fluid present, the light continues through the glass and reflects off the back of the level gage, providing a black color for fluid level regardless of the actual color properties of the process fluid. If fluid is not present, the light is reflected off the glass back towards the user, providing a shiny silver or mirror-like appearance to indicate vapor space.
transparent cross section Jerguson® Transparent Level Gages are selected for interface level indication, dirty service or any application that requires the use of a shield to protect the glass from corrosion. A transparent gage is also known as a "thru-vision" gage since the gage is constructed with two pieces of flat polished glass assembled on opposite sides of the level gage chamber. Since the user can see straight through the gage, it is also easy to view the fluid properties, such as color, whereas this would not be possible with a reflex gage. The use of an illuminator is always recommended on a transparent gage.
