Working Principle:
The reflex level gauge is used to see the water level in the boiler drum. The working principle is based on the light separator & retraction laws.When in operation the chamber is filled with water in lower zone & vapors or gases in the upper zone. The liquid level is distinguished by the different brightness of the glass in liquid & in vapor zone. The liquid level (water) in the chamber will be seen blacky where as the vapor region will reflect silvery in color and then level can be distinguished.
Construction:
This instrument is made of a metal body chamber & window on front side. The window is covered by glass plate with sealing gasket and hold in position by `U’ bolt & nut. The glass length varies in length from 200mm to 400mm.The mounting on boiler vessel flanged connection. The level gauge can be provided with isolating valves for isolation.
