Long Range Radar Water Level Sensor for Rivers, Reservoirs & Industrial Tanks | IoT Level Monitoring System
High-precision non-contact radar water level sensor for rivers, reservoirs, groundwater, and industrial tanks. Long-range IP68 device for IoT hydrological and industrial monitoring systems.
Product Introduction
The KH.LBRD High-Precision Radar Water Level Sensor is a long-range non-contact level measurement device designed for continuous monitoring of rivers, reservoirs, groundwater wells, industrial tanks, and liquid storage systems.
Using advanced radar ranging technology, it measures water level without physical contact, ensuring stable and accurate performance even in harsh environments such as waves, heavy rain, sediment, foam, dust, and temperature fluctuations.
It is widely used in hydrological monitoring stations, industrial automation systems, flood warning networks, and IoT-based smart water management platforms, providing real-time and reliable level data for decision-making and control systems.
How It Works
The radar emits electromagnetic waves toward the liquid surface and calculates distance based on the reflected signal.
This non-contact method ensures:
- No corrosion or fouling
- No mechanical wear
- Stable operation in extreme environments
