Working principle and composition of two-color water level gauge B49H-10/2-W without blind area

No blind area series two-color water level meter observation holes in the two straight lines of the table body, through the staggered combination of observation holes to eliminate the blind area in the middle. The red and green light emitted by the light source are directed to the observation window of the surface body respectively. In the vapor phase part of the surface body, the red light is directed to the front, while the green light is slanted to the wall and absorbed. At the same time, in the liquid phase, the water refraction causes the green light to shine forward and the red light to slant off the wall and be absorbed. So in front of the observation will get steam red, water green; Full of steam all red, full of water all green display effect. This series of two-color water level meter is mainly composed of table body, valve, light source assembly (light source box, observation cover), switching power supply; Table body and light source assembly.
