Transparent Liquid Level Gauge

Simco Transparent liquid level gauges consist of two flat transparent glasses where the light can enter / exit from the back to the front of the gauge thus illuminating the liquid level which is contained in the chamber separating the  two glasses. The liquid level is indicated by the different transparency of the two media.

A source of light (Illuminator) maybe located at the back of the transparent level gauge, light from the illuminator passes through the process fluid and is then viewed by the observer so that a level measurement can seen.

This type of gauge is used for measuring both total and interface liquid level of fluids in a vessel and also allows the use of Mica shields on the glass for excellent protection in  steam service (if the environment is corrosive then Kel-F shields should be used instead).
