Reflex level gauges
Reflex level gauges allow the medium to be viewed through a reflex glass. The side of the glass exposed to the medium has a prismatic surface, while the other side is smooth. The medium level inside the gauge is indicated by the principle of light refraction: the liquid-filled area absorbs the rays of light completely and appears dark, while the rays of light are fully reflected in the gas/air-filled area, which subsequently appears bright.
Reflex level gauges offer significant advantages in terms of low purchase and maintenance costs, as well as ease of level reading. However, they cannot be used in certain cases—for example, when the separation level between two liquids must be read, when discerning the colour of a liquid is required, or when measuring high-pressure water steam.
A105 and SS 316L are used as standard materials; alloy or other materials are available on request.
