1. We can make it according your specification
2. It widely used in steamed industry
Liquid level gauges for steam and prcess applications
Indication
Very clear
Steam-Vapour space silver white Water-Liquid space dark
The principle of the reflex glass isbased on the difference in the refractive
Indices of liquid and gas or, in particular, of water and steam. The
Liquid column is contained within the recess of the centre-piece behind the
Gauge glass which is clamped within the gauge body.
If a ray of light encounters the surface of one of the 45 ° C slanted grooves in
The gas or steam space it is reflected to the opposite surface of the groove and
From there totally reflected back into the direction of observation. The steam
Or gas space therefore appears silver-white.
