Reflex level gauges may be applied in numerous applications to include feed water heaters, DE aerators, boiler drums, and other types of tanks.
For a reflex level gauge, within the recess of a liquid chamber and behind a single piece of glass, is the liquid column that clamps down onto the gauge body. This glass is flat on the outside and on the inside has a series of prism grooves that face the vapour and liquid space. Based on whether light enters the vapour or liquid space, it is reflected or absorbed, respectively.
Once light encounters a groove’s surface within the vapour space it reflects to the surface of the grooves on the opposite side, followed by reflecting completely back to the observation direction. During the liquid phase, light is absorbed, which creates one display for the area that is covered by liquid and another display for the area located above the liquid.
Using the prism glass, a reflex level gauge accurately measures liquid inside the vessel. When light hits the glass where there is no liquid, the prism reflects the light directly out of the gauge. Known as the “dry” area, a silver colour is displayed while the “wet” part is displayed in black. The contrasting colours create a clear delineation line that makes it easy to view the measurement.
The external chamber is a self-contained cage designed for use with our top mounting level transmitters or switches. Quality construction and a wide selection of configurations make this cage an ideal means of utilizing the power of our many technologies without mounting directly into the process vessel.
