Product Introduction
The KH.WLX is a high-precision, low-power, and non-contact radar water level meter that operates on FMCW (Frequency Modulated Continuous Wave) technology. Compact and lightweight, it delivers reliable performance with features such as high accuracy, strong anti-interference capability, easy installation, and maintenance-free operation, making it ideal for long-term field use.

Features
• Long service life – Industrial-grade design with anti-condensation, waterproof, and advanced lightning protection features. Operates stably across an ultra-wide temperature range, suitable for various field environments.
• FMCW radar technology – Enables non-contact measurement unaffected by weather, sediment, or floating debris. Simple installation and maintenance-free operation ensure long-term reliability.
• Energy efficient – Intelligent combination of measurement and sleep modes reduces power consumption for long-term unattended monitoring.
• Fast response – Extremely short measurement time, with a minimum response time of 100 ms.
• Verified accuracy – Fully compliant with GB/T 15966-2017 “Basic Parameters and General Technical Conditions for Hydrological Instruments.”

Application Scenarios
Ideal for water level monitoring in rivers, lakes, tides, and reservoirs, as well as urban flood and drainage monitoring during the rainy season. It is also suitable for water supply, sewage systems, and auxiliary water treatment operations.
