Solide SLDL6100 Series Bi-Colour Detect Water Level Gauge
May 29, 2026| 1. Product Core Positioning
The SLDL6100 Series Bi-Colour Water Level Gauge is a high-precision measuring instrument specifically developed for water level monitoring of boilers and pressure vessels. It feeds back the real water level inside the vessel in real time based on the communicating vessel principle. The product is available in a diversified and serialized range of models and specifications, featuring high measurement accuracy, safety and reliability, easy maintenance, and long service life. It can adapt to water level monitoring needs under different working conditions and serves as key equipment ensuring safe boiler operation.
2. Working Principle
The water level gauge forms a communicating vessel structure with boilers and pressure vessels, measuring the real water level inside the vessel in real time by virtue of the communicating vessel principle. During boiler operation, the drum water level fluctuates with changes in load, combustion conditions, and feedwater flow rate. The SLDL6100 Series Water Level Gauge enables continuous and intuitive monitoring of water level dynamics to keep the water level within a safe range, eliminating potential safety hazards caused by abnormal water levels at the source, making it a core monitoring device for safe boiler operation.
3. Core Technical Advantages
1) Powerful Self-Flushing Function (Maintenance-Free)
The top of the water level gauge body is equipped with a dedicated condenser. When saturated steam from the boiler drum flows through the condenser, a large amount of salt-free pure water is generated through heat dissipation. The pure water continuously flows along the inner surfaces of the two rows of windows, powerfully flushing dirt on the mica of the observation window and preventing impurity adhesion. Meanwhile, the pure water flows back into the body cavity, continuously replacing the saturated water inside and turning the cavity water into saltfree and impurityfree pure water. This keeps the window free of fouling with clear and longlasting display, improves observation effectiveness, greatly extends the service life of window components, and reduces maintenance frequency.
2) Precise Heating Function
The product is designed with additional heating holes on the body. Saturated steam from the drum enters the heating holes through the steamside sampling port, continuously heating the water level gauge body and the water column inside the cavity. This ensures the water temperature inside the cavity remains consistent with that of the saturated water in the drum. This design completely eliminates measurement deviations of traditional water level gauges caused by low water temperature and high density, achieves accurate matching of water level display with the real drum water level under all working conditions, solves the problem of measurement distortion in lowtemperature environments, and guarantees allweather accurate and reliable monitoring data.
4. Product Value and Application Scenarios
Focusing on pain points in industrial water level monitoring, the SLDL6100 Series Bi-Colour Water Level Gauge delivers three core values: maintenancefree operation, high precision, and long service life through dual core technologies. It eliminates frequent manual cleaning and calibration, lowering equipment operation and maintenance costs. Its stable and reliable performance reduces the risk of equipment downtime due to failures and ensures continuous operation of boilers and pressure vessels. The product is widely used in utility boilers, industrial boilers, pressure vessels and other scenarios, meeting stringent water level monitoring requirements in power, petrochemical, metallurgical and other industries, and safeguarding the safety of industrial production.
In the future, Solidat will continue to deepen its presence in the industrial measurement sector, constantly optimize the technical performance of the SLDL6100 Series Bi-Colour Water Level Gauge, enhance product reliability and applicability through innovative technologies, provide global industrial customers with higherquality water level monitoring solutions, and help enterprises achieve safe, efficient and stable production.
