The Dual color water level gauge for Steam Drum B49H-10 is a liquid level monitoring device designed for boiler drums, mainly used to directly observe the water level in the drum. It uses red and green LED light sources to shoot light into the observation window of the water level meter through the principle of optical reflection and refraction, so that the operator can clearly see the water level in the drum. The equipment is widely used in power, chemical, steel and other industries to ensure the safe operation of boilers.

Technical parameters

• Measuring range: 300mm to 2000mm.

• Working temperature: -10℃ to 450℃.

• Nominal pressure: 1.6MPa, 2.5MPa, 4.0MPa.

• Display color: green for water and red for steam.

• Material: carbon steel.

• Power supply: AC 36±4V.

• Power: 6W to 10W.

Working principle

The Dual color water level gauge for Steam Drum B49H-10 works through optical principles. When light passes through liquid and gas, it will reflect and refract due to the different refractive indices. By installing red and green LED light sources in the observation window of the water level gauge, the operator can directly observe the change of water level. The display effect of the water level gauge is: water is displayed in green and steam is displayed in red. This design not only improves the accuracy of water level monitoring, but also enhances the intuitiveness of operation.

Product Features

• No power supply required: The Dual color water level gauge for Steam Drum B49H-10 does not require external power supply during normal operation, which is especially important in emergency situations such as power outages.

• Easy installation: No calibration is required, and the installation process is simple and quick.

• Wide range of applications: Applicable to a variety of media, not affected by the chemical or electrical properties of the media.

• ​​High reliability: Can still work stably under high temperature and high pressure environment.

• No blind spot design: By staggered combination of observation holes, the intermediate blind spot is eliminated to ensure the comprehensiveness of water level monitoring.

Dual color water level gauge for Steam Drum B49H-10 is widely used in water level monitoring of boiler drums, pressure vessels and other equipment. It is not only suitable for high temperature and high pressure environments, but also can work stably in corrosive media. In addition, the device can also be used in the chemical, steel and other industries to ensure the safe operation of the equipment.

Installation and Maintenance

• Installation: Ensure that the installation position is correct and the connection is firm to avoid leakage caused by improper installation.

• Maintenance: Regularly check the tightness of the water level gauge and the brightness of the light source, and replace damaged parts in time.

Dual color water level gauge for Steam Drum B49H-10 has become an ideal choice for boiler drum water level monitoring with its high reliability, intuitive display effect and wide range of applications.
