KH.WFH Float Water Level Gauge for Accurate Liquid Level Measurement in Reservoirs Rivers Groundwater and Industrial Tanks
Digital Water Level Sensor for SCADA IoT Telemetry Flood Control Hydrology and Industrial Monitoring Applications
Product Introduction
The KH.WFH Float Water Level Gauge is a high-precision digital liquid level sensor designed for accurate water and liquid level monitoring in reservoirs, rivers, groundwater wells, lakes, and industrial tanks. By combining mechanical float measurement with advanced electronic signal processing, the sensor converts float displacement into digital signals, providing stable, reliable, and real-time water level readings for long-term field deployment.
Constructed with robust corrosion-resistant materials, the KH.WFH is ideal for harsh hydrological, environmental, and industrial conditions. Its compact design and flexible output options allow seamless integration with SCADA systems, IoT platforms, telemetry monitoring networks, flood control projects, and industrial automation applications.
