Process Level Gauge - Reflex

Product Code: Process Level Gauge - Reflex

Reflex Level Gauge — High-Contrast Liquid Level Indication

The Reflex Level Gauge is available across ANSI Class 150 to ANSI Class 1500 and is ideally suited for low-pressure steam boilers, gas-liquefaction plants, reactors, and storage vessels. It provides a crisp, unmistakable indication of liquid level even in fluctuating or cyclic-duty systems.

The gauge operates on the optical principle of light absorption and reflection: light entering the gauge is absorbed by the liquid space, appearing dark, and reflected in the vapour space, appearing bright silver — delivering a clear visual boundary between gas and liquid phases.
