KH.WFH Float Water Level Gauge
Digital Liquid Level Sensor for Reservoirs, Rivers, Groundwater, and Industrial Monitoring
Product Introduction
The KH.WFH Float Water Level Gauge is a high-precision digital liquid level sensor that combines mechanical float measurement with electronic signal processing to deliver accurate, real-time water and liquid level monitoring. Using an encoder, float displacement is converted into digital signals, ensuring stable and reliable readings for long-term deployment.
Designed with robust construction and corrosion-resistant materials, the KH.WFH is suitable for harsh environments, including reservoirs, lakes, rivers, groundwater wells, and industrial liquid tanks. Its compact design and flexible outputs make it ideal for integration with SCADA, IoT, and telemetry monitoring systems.
Key Features
- Stable and Reliable
Optimized mechanical and electronic design provides long-term durability, strong anti-interference capability, and consistent measurement stability. - High Precision
Accurate water level measurement with an error of ≤±2 cm or 0.2% FS, providing fine resolution across a wide measurement range. - Power-Off Memory
Built-in tracking and memory function retains water level data even after power interruptions. - Flexible Output Options
Supports Parallel Gray code, 4–20 mA analog, RS485, and SSI Gray code for seamless integration with SCADA, IoT, or telemetry systems. - Durable Materials
Stainless steel measuring cable and corrosion-resistant float ensure reliable long-term operation in outdoor, industrial, and hydrological environments.
