KH.LDX Non-Contact Radar Current Meter | High-Precision Flow Velocity Sensor for Rivers and Flood Monitoring
Product Introduction
The KH.LDX Radar Current Meter is a high-precision, non-contact flow velocity sensor designed for hydrological monitoring, flood forecasting, and smart water management. Using advanced radar technology, it outputs accurate flow velocity data for rivers, channels, culverts, and urban drainage systems. The integrated microstrip antenna, RF circuit, and signal processing unit ensure fast, stable, and reliable measurements. Compact, energy-efficient, and easy to install, the KH.LDX is ideal for long-term deployment in harsh field environments.
Key Features
Industrial-Grade Durability: Waterproof, anti-condensation, and lightning-protected housing with a wide operating temperature range for reliable field operation.
Non-Contact Radar Measurement: Flow velocity readings are unaffected by weather, sediment, debris, or vegetation, ensuring consistent data.
High Precision: Provides ±0.01 m/s accuracy and 0.01 m/s resolution for reliable hydrological monitoring and research.
Energy-Efficient Operation: Intelligent measurement and sleep modes reduce power consumption, ideal for remote monitoring stations.
Compact and Easy Installation: Lightweight design supports rapid deployment, maintenance-free operation, and seamless integration with IoT monitoring systems.
Application Scenarios
Rivers and channels — Continuous flow velocity monitoring for flood prevention, water resource management, and hydrological research.
Urban flood monitoring — Real-time flow detection at stormwater outlets, low-lying areas, and city drainage systems.
Culverts and pipelines — Non-contact monitoring for underground pipe networks, industrial channels, and irrigation systems.
Hydrological monitoring networks — Works seamlessly with water level sensors to provide complete discharge and flow monitoring solutions.
