Product Introduction
The KH.LDX radar current meter is a high-precision non-contact flow velocity sensor designed for hydrological monitoring, flood control, and smart water management applications. Built with an integrated microstrip antenna, RF circuit, and signal processing unit, it directly outputs accurate water flow velocity data. With an ultra-sensitive low-noise amplifier and advanced radar technology, the KH.LDX provides fast, stable, and reliable velocity measurement even in harsh environments. Its compact design, low power consumption, and easy installation make it ideal for long-term field deployment in rivers, channels, culverts, and drainage systems.

Key Features

• Industrial-grade design — Waterproof, anti-condensation, lightning-protected housing with wide operating temperature range ensures durability in extreme environments.

• Non-contact radar technology — Unaffected by climate, sediment, floating debris, or vegetation, ensuring stable and accurate flow velocity measurements.

• High precision measurement — Provides flow velocity data with ±0.01m/s accuracy and 0.01m/s resolution for reliable hydrological monitoring.

• Energy-efficient operation — Measurement and sleep modes work together to reduce power consumption, ideal for remote monitoring stations.

• Compact and easy to install — Lightweight design allows quick installation, maintenance-free operation, and integration with IoT-based monitoring systems.

Typical Applications
The KH.LDX radar current meter is widely used in hydrological monitoring, flood forecasting, and smart water resource management:

• Rivers and Channels — Continuous flow velocity monitoring for flood prevention, water resource allocation, and hydrological research.

• Urban Flood Monitoring — Real-time detection of flow velocity and discharge at stormwater outlets, low-lying areas, and city drainage systems.

• Culverts and Pipelines — Non-contact monitoring of underground pipe networks, industrial channels, and irrigation systems.

• Hydrological Monitoring Networks — Works with water level sensors to provide complete discharge and flow monitoring solutions.
