Steam Level Gauge - Reflex

Product Code: Steam Level Gauge - Reflex

Reflex Level Gauge — Clear, Reliable Indication for Industrial and Steam Applications

The Reflex Level Gauge from John Moncrieff Ltd provides a highly visible, direct reading of liquid levels in vessels, boilers, and process equipment. Operating on the proven principle of light absorption and reflection, it delivers a distinct black-and-silver contrast between gas and liquid phases — ensuring accurate and immediate level recognition even in challenging environments.

Available in pressure ranges from ANSI Class 150 to ANSI Class 1500, this gauge is particularly suited for low-pressure steam boilers, gas liquefaction plants, reactors, and storage vessels. Its rugged construction, high optical clarity, and dependable operation under cyclic conditions make it a mainstay across global process industries.

Operating Principle

In a Reflex Gauge, incident light is absorbed by the liquid column, creating a dark appearance, while it is reflected in the vapour space, producing a bright silver reflection. The resulting sharp contrast provides unambiguous level identification without auxiliary lighting.
