KH.WFH Float Water Level Gauge | Digital Liquid Level Sensor for Reservoirs and Industrial Monitoring
Product Introduction
The KH.WFH Float Water Level Gauge is a high-precision digital liquid level sensor that integrates mechanical and electronic technologies for accurate water and liquid level measurement. The sensor converts float movement into a real-time digital signal through an encoder, providing precise monitoring of water level height and variations. Its robust design ensures reliable, long-term operation in reservoirs, lakes, rivers, industrial tanks, and groundwater wells.
Key Features
Stable and Reliable: Optimized mechanical structure provides long-term durability, strong anti-interference performance, and consistent measurement stability.
High Precision: Measures water levels with an accuracy of ≤±2 cm or 0.2% FS, offering fine resolution across a wide measurement range.
Power-Off Memory: Retains water level data after power interruptions with built-in tracking and memory function.
Multiple Output Options: Supports parallel Gray code, 4–20 mA analog, RS485 serial, or SSI Gray code outputs for flexible integration with SCADA or IoT systems.
Durable Materials: Stainless steel measuring cable and corrosion-resistant float ensure long-term outdoor and industrial use.
Application Scenarios
Continuous water and liquid level monitoring for reservoirs, lakes, rivers, and hydrological stations
Groundwater wells, water supply systems, and irrigation networks
Industrial liquid tanks, chemical storage, and wastewater systems
Pumping stations and drainage projects
Widely used in hydrology, water conservancy, environmental monitoring, and industrial process control
