Working principle
The observation hole of this water level gauge is on two straight lines in the length direction of the watch body, and the middle blind area is eliminated by staggered combination of observation holes. The red and green light emitted by the light-emitting diodes are directed to the observation window of the watch body respectively. In the vapor phase part of the watch body, the red light is directed straight ahead, while the green light is slanted to the wall and absorbed; at the same time, in the liquid phase part , due to the refraction of the water, the green light is directed straight ahead, and the red light is absorbed obliquely to the wall. Therefore, if you look straight ahead, you will get steam red and water green; steam full red and water full green display.
