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.

Reflex gauges function efficiently without specific illumination, relying on natural daylight, and only need artificial l
