Product Introduction

The KH.WLX Non-Contact FMCW Radar Water Level Meter is a high-precision, compact, and lightweight radar water level sensor designed for real-time hydrological monitoring and smart water management. Using Frequency Modulated Continuous Wave (FMCW) radar technology, it measures water surface distance without physical contact, converting the data into accurate real-time water level readings.

Unaffected by rainfall, fog, waves, sediment, floating debris, or water impurities, the KH.WLX is ideal for long-term deployment in rivers, lakes, reservoirs, canals, and urban drainage systems. With low power consumption, strong anti-interference performance, and maintenance-free design, it is perfect for IoT-enabled remote monitoring, flood early warning systems, and smart city water management projects.
