Reflex Level Gauge
Reflex level gauges are commonly used for level detection within a specific vessel, and the primary principle is based on the difference in refractive indices of vapor and liquid.
Reflex gauges, also referred to as prismatic level gauges, offer a well-defined image of water levels. This reduces risks of distortions or reading areas. Because of this, a reflex level gauge can be installed in a tilt-view or vertical position to produce even greater accuracy in readings along with a much better degree of reliability. As imagined, this is highly beneficial for many industries.
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 color is displayed while the "wet" part is displayed in black. The contrasting colors create a clear delineation line that makes it easy to view the measurement.
APPLICATIONS
Reflex glass level gauges can be used in most of the cases and offer great advantages in terms of: low initial cost, low operating cost, easy level reading.
Reflex level gauges cannot be used in certain cases as for example:
- When the separation level between two liquids must be read (interface)
- when besides the level indication, the observation of the liquid color is required
- When the process fluid is high-pressure water steam, since in this case the glass must be protected from the solvent action of the boiler water by using mica shields
- When the process fluid is such that can corrode the glass (e.g., high temperature alkaline solutions or hydrofluoric acid), since ica shields or Polytrifluorochloroethylene shields must be used to protect the glass
Transparent Level Gauge
Apart from glass tube level gauges, transparent level gauges are always fitted with two plate transparent glasses between which the fluid is contained. The fluid level is indicated as the result of the different transparency of the two media and in some cases (for water steam), by conveying upwards on to the surface of separation (between liquid and gaseous substances) a source of light located at the back of the gauge, the rays of which are totally reflected down to the observer.
APPLICATIONS
Transparent level gauges are suitable for almost all installations. In fact they permit:
- The use of mica shields or Polytrifluorochloroethylene shields to protect the glass from the corrosive action of the process fluid
- The observation of interface
- The observation of the liquid colour

Tubular Level Gauge
Tubular Level Gauge is one of the simplest forms of level indication used over the years. These level gauges are used in low or medium pressure conditions. Tubular Level Gauge is mounted on the side of the tank or vessel. It consists of Glass Tube, Protection Frame, packing material, End blocks, Isolation Valves, Vent and Drain Plugs
