Product Introduction

The KH.LDX Non-Contact Radar Current Meter is a high-precision flow velocity monitoring instrument designed for hydrological observation, flood forecasting, and smart water management applications. Utilizing advanced microwave radar technology, it provides accurate, reliable, and real-time flow velocity data for rivers, open channels, culverts, and urban stormwater drainage systems.

The sensor integrates a microstrip antenna, RF circuit, and a high-performance signal processing unit, ensuring fast response, excellent stability, and consistent measurement accuracy. Featuring compact structure, low power consumption, and simple installation, the KH.LDX is ideal for long-term, unattended deployment in harsh outdoor environments.

Key Features

• Industrial-Grade Durability
  Waterproof and anti-condensation structural design with enhanced lightning protection and a wide operating temperature range ensures reliable performance in severe weather and challenging field environments.
• Non-Contact Radar Measurement
  Performs flow velocity measurement without contact with water, remaining unaffected by sediment, floating debris, vegetation, waves, turbidity, or changing weather conditions.
• High Measurement Accuracy
  Provides flow velocity accuracy up to ±0.01 m/s with a resolution of 0.01 m/s, ensuring precise and dependable hydrological data collection.
• Energy-Efficient Operation
  Supports intelligent switching between measurement and sleep modes, significantly reducing power consumption and making it suitable for remote, solar-powered, or IoT monitoring stations.
• Compact and Easy Installation
  Lightweight construction allows rapid on-site installation and deployment. Designed for maintenance-free operation and seamless integration with IoT, telemetry, and hydrological monitoring platforms.

Application Scenarios

• Rivers and open channels — continuous flow velocity monitoring, flood warning, and water resource management

• Urban flood monitoring — stormwater outlets, low-lying urban areas, drainage and stormwater management systems

• Culverts and pipelines — non-contact monitoring for underground pipe networks, irrigation channels, and drainage tunnels

• Hydrological monitoring networks — combined with water level sensors to support complete discharge calculation and flow analysis
