Steam Level Gauge - Bi-Colour

Product Code: Steam Level Gauge - Bi-Colour

Bi-Colour Steam Level Gauge — Precision Visibility for High-Pressure Steam Systems

The Bi-Colour Steam Level Gauge is designed specifically for high-pressure boilers operating up to 210 bar saturated steam. Featuring distinct red and green phase indication, it provides clear, instant differentiation between steam and water levels, ensuring safe, accurate monitoring in demanding industrial and power-generation environments.

Engineered for reliability under severe operating conditions, this gauge combines robust forged alloy construction with advanced optical technology to deliver an unmistakable colour contrast reading — even in low-visibility or remote-monitoring setups.

Operating Principle

The bi-colour optical system directs light through the gauge body, producing a red indication for the steam space and a green indication for the water space. The sharp colour contrast eliminates ambiguity and enables quick, confident level assessment, even at long distances or in poor lighting conditions.
