Reflex Level Gauge is a sophisticated device used to measure liquid levels in a container. It utilizes a reflex glass with a prismatically grooved face pointing towards the gauge chamber. This setup facilitates a clear distinction between liquid and gas/vapor zones based on their brightness, resulting in an efficient and easy-to-read level indication.
Reflex Level Gauge with Level Gauge Glass
Reflex glass level gauges
Materials:
Level gauge glass. The critical component of a reflex level gauge is its level gauge glass. This glass is engineered to withstand the harsh conditions of various industrial applications, exhibiting resilience even under high pressure, high temperatures, or corrosive environments. It can be easily sourced and installed, thanks to the convenience of online shopping.
Level Gauge Working Principle:
The Reflex Glass Level Gauges operate based on light refraction and reflection principles. These gauges utilize specially crafted glass angled towards a chamber with 90° prismatic grooves. During usage, liquid fills the lower chamber section, while gases or vapors occupy the upper part. The liquid level is discerned from the distinct brightness contrast between the zones. Reflex gauges function efficiently without specific illumination, relying on natural daylight, and only need artificial lighting at night. The variation in brightness is achieved as follows:
The liquid zone appears significantly dark during operation due to the refraction of most light rays inside the liquid, resulting in an almost black appearance because the non-reflective gauge chamber interior prevents the refracted rays from being externally visible.
In contrast, the gas/vapor zone appears nearly silver due to total reflection of light rays at the glass/gas-vapor interface. This reflection, causing a 90° turn, makes the rays observable, thus giving the zone a bright silver appearance.
