Transparent level gauge is also known as transparent level indicator,transparent glass level gauge. Transparent level gauges are usually fitted with two plate transparent in glasses between which the fluid is contained. When the upper chamber is filled with gas and the lower chamber is filled with liquid, the fluid level is indicated as the result of the different transparency. At the back of the transparent level gauge is a light source with rays reflecting down to the observer making it possible to read or estimate the measurement.
For most application, a transparent level gauge is appropriate. Compared with reflex level gauge, transparent level gauge can be used in higher working pressure and some corrosive fluid environment.
To avoid leakage in case of glass breakage, safety ball-check device is usually provided in cross-fittings or shut-off valves.To protect glass surfaces from corrosive action of the process fluid, Transparent Level Gauges can be fitted with Mica shields or Polytrifluorochloroethilene shields.
