The liquid level is distinguished by the different brightness of the reflex glass in the water or in the steam space. Where there is liquid in contact with the glass, the incidental light is refracted to the inside of the gauge and absorbed; in the steam space, the inci-dental light is reflected against the glass grooves and the glass.
Refer to the dimensios tab to help choose size number.
Reflex level gauges can be used in most applications and offer great advantages in terms of;
* Low initial cost
* Low operating cost
* Reflex level gauges should not be used in certain cases for example:
- When the separation level between two liquids has to be read (interface);
- When besides the level indication, the observation of the liquid colour is required
- Where the media is corrosive or a solvent. Here a transparent gauge must be used with a mica to protect the glass.
