Lighting Device and Remote Monitoring System
1.Principle of bi-color display water level gaute
The air phase in the water Level gauge is colored red and the liquid phase is green ensuring a very clear display of the water Level.
When the prism shaped liquid chamber of the water level gauge is filled with a clear liquid, due to the prism effect of the liquid chamber section, the light injected is bent extensively. However, when the liquid chamber is filled with air (gas) the light bending effect is slight and almost all of the injected light travels straight, and this property is utilized.
When the color filters are set in the illuminator, as shown in the diagrams on the right the following different light phenomena occur in the air phase section (Fig. 1) and the liquid phase section (Fig. 2).
In the air phase section (Fig. 1) the red light is transmitted, passes through and appears in the visible section. However, the green light undergoes turbulent reflections on the inner wall of the liquid chamber and does not become visible. ln the liquid phase section (Fig. 2), the green light is bent and then proceeds directly and is transmitted to appear in the visible section. The red light is bent and undergoes turbulent reflections on the inner wall of the liquid chamber and does not become visible.
Consequently, the air phase appears as red and the liquid phase as green. Thanks to this red and green bi-color system, the water level can be clearly seen.

3.Remote Monitoring System
In the system for remote monitoring of the water level, the image of the water level gauge divided into bi-color phases can be transmitted by mirrors or by I.T.V. as shown in
Fig 3(Remote Monitorring usin Mirrors),
Fig 4(Remote Monitorring usin Mirrors),
Fig 5(Remote Monitoring using I.T.V).
In order to view the bi-color image correctly, please put the mirror or I.T.V.monitor in
the correct position as shown bythe mark "VIEW O'.
