KENCO Flat Glass Gauges are used where direct visual observation of process fluids is required.  These gauges are suitable for a wide range of applications with pressures up to 4000 psig (275.79 bar) @ 100°F (37.7°C), and temperatures up to 750°F (398.8°C) @ 2300 psig (158.57 bar).  KENCO gauges are available in a wide variety of construction materials, connections and other options to meet most specifications.

Reflex gauges have a single piece of glass, mounted on one side of the chamber. This piece of glass is flat on the outside, and has a series of prisms on the inside, facing the process fluid. When light strikes the portion of the glass covered by a liquid, the light is reflected from the back of the chamber. This area appears “black”. When light strikes the glass where no liquid is present, the prisms reflect the light directly out of the gauge. This area appears “silvery”. Reflex gauges provide an excellent way to measure clear, or difficult to see fluids. The “silvery”/”black” interface is easy to see from several feet away.

Why Use Flat Glass Gauges

Flat Glass Gauges have been in use for over 100 years.  They give you the ability to directly view the process fluid under temperature/pressure conditions that would render most other level technologies useless.  Their construction is very robust, and reliable.  They define the term “simple to use”.  After installation, the only tool you will need is your eyes. Flat Glass Gauges are relatively inexpensive as compared to most other level technologies.
