Measuring Principle
The principle of reflex level gauge is based on the difference in the refractive indices of liquid and vapor. The gauge glass has prismatic right-angled grooves on the side facing the liquid. The level is indicated as a result of the light refraction principle. The liquid filled area completely absorbs the rays of light and appears dark; while the rays of light are totally reflected in the gas/air filled area which appears bright.
