Dual color water level meter B49H-10/2-W

Short Description:

The dual color water level meter B49H-10/2-W is local display instrument equipment, mainly installed on the boiler drum or various liquid pressure vessels to directly observe the water level. The dual color water level meter displays the boiler water and steam parts through optical principles, which are colored. The steam is red, the water is green, and when the steam is full, it is all red, and when the water is full, it is all green. It automatically and continuously changes with the water level, and is a reliable instrument for monitoring the boiler water level and ensuring the safe operation of the boiler.

Product Detail

Working principle and composition

The observation holes of the dual color water level meter B49H-10/2-W are located on two straight lines of the meter body, and the middle blind area is eliminated by interleaving and combining the observation holes. The red and green lights emitted by the light source are respectively directed towards the observation window of the meter body. In the vapor phase part of the meter body, the red light is directed directly in front, while the green light is oblique and absorbed on the wall; at the same time, in the liquid phase, due to the refraction of water, green light is directed straight ahead, while red light is angled onto the wall and absorbed. Therefore, observing directly in front will result in vapor red and water green; the display effect of full red for steam and full green for water. This series of dual color water level gauges mainly consists of a meter body, a valve, a light source assembly (light source box, observation cover), and a switching power supply; Meter body and light source assembly.

Purpose and characteristics

1. The dual color water level meter B49H-10/2-W is currently an advanced primary water level instrument that is intuitive and reliable. It is used for displaying water in industrial steam boilers and steam locomotive boilers.

2. The dual color water level meter has a simple and reasonable structure, and is convenient for flushing.

3. Installation and use do not require any adjustments.

4. The dual color water level meter B49H-10/2-W is not affected by water quality and has a clear water vapor interface.

5. When there is a power outage, lighting with other light sources can still distinguish the water level.

6. The dual color water level indicator light source has a long lifespan.
