Product Introduction
The KH.LBRD radar water level meter adopts advanced electromagnetic wave ranging technology with precise time measurement. The sensor emits electromagnetic waves to the water surface and receives the echo, calculating parameters such as the distance from the sensor to the water surface, the rate of change of distance (radial velocity), azimuth, and height.
This innovative radar technology achieves a major advancement in water level monitoring, providing millimeter-level accuracy, long measurement range up to 70 meters, high reliability, and easy installation. It can be connected to computers, PLCs, or RTUs through standard interfaces to form a comprehensive water level monitoring and control system.

Features
• High precision: Utilizes high-frequency microwave ranging technology with a measurement accuracy of ±3mm for precise and stable data output.
• Simple installation and maintenance: Non-contact measurement with no mechanical wear, allowing for continuous online monitoring and 24-hour unattended operation.
• Strong anti-interference performance: Measurement results are independent of water quality and unaffected by floating objects, ice, or water flow turbulence.
• Durable and cost-effective: Designed for long service life with low power consumption and robust materials.

Application Scenarios
The KH.LBRD radar water level meter is suitable for monitoring:
• Water levels of rivers and reservoirs
• Open channels and dam tailwater
• Upstream and downstream water levels of reservoirs
• Flood monitoring, mountain torrent prevention, and water level control in pressure regulating towers or wells
It is widely used in water conservancy, hydrology, flood control, and environmental monitoring applications.
