Product Introduction

The KH.WLX Non-Contact Radar Water Level Meter is a compact, lightweight, high-precision water level monitoring instrument developed by KEHAO. It uses FMCW (Frequency Modulated Continuous Wave) radar technology for non-contact measurement, converting the distance to water surface into an accurate water level reading.

The sensor is unaffected by weather, sediment, or floating debris, making it ideal for long-term deployment in rivers, lakes, reservoirs, urban flood monitoring, mountain flood early warning, water supply, sewage systems, and other hydrological applications. Its low power consumption, strong anti-interference capability, and maintenance-free design ensure reliable performance in diverse field conditions.

Key Features
