Product Introduction

The KH.LDX Non-Contact Radar Flow Velocity Meter is a high-precision hydrological monitoring device designed for real-time measurement of river surface velocity in rivers, streams, canals, and open channel environments.

Using advanced microwave Doppler radar technology, the device measures water surface velocity without direct contact with water, providing stable and reliable performance in complex conditions such as flood events, turbulent flows, sediment-rich rivers, vegetation interference, and floating debris environments.

Compared with traditional contact-based flow velocity sensors, the KH.LDX eliminates mechanical wear and reduces maintenance requirements, making it suitable for long-term deployment in remote hydrological monitoring locations.

The radar velocity sensor is widely applied in:

• River flow velocity monitoring
• Flood early warning systems
• Hydrological monitoring stations
• Irrigation channel management
• Smart water management platforms
• Water resource monitoring networks

By providing accurate surface velocity data, the KH.LDX supports flow analysis, flood forecasting, emergency response, and intelligent water resource management.

How It Works

The KH.LDX uses microwave Doppler radar technology to measure surface flow velocity.

The radar sensor continuously transmits microwave signals toward the water surface and analyzes the frequency shift of reflected signals caused by water movement.

The system calculates surface velocity based on Doppler frequency variation.

This non-contact measurement method provides:

• No mechanical wear or moving components
• No blockage caused by sediment, vegetation, or floating debris
• Stable operation during flood events and turbulent flow conditions
• Reliable velocity measurement for long-term monitoring
