To simplify installation, streamline multi-device interface coordination and data protocol integration, enable remote debugging/maintenance/upgrades, reduce operational costs, and improve real-time monitoring, data management, and decision-making capabilities in water and rainfall monitoring station projects:

The Integrated Radar Water Level Meter (RD-300-CR) serves as the core data terminal for unified monitoring of water level, rainfall, and imagery. This system integrates solar power supply, RTU, and multi-parameter sensors (water level/flow relationship, rainfall, imagery, weather, water quality, etc.) into a compact, all-in-one monitoring station. It supports image-text overlay and simultaneous data-image transmission to multiple central stations.

As the system’s central control unit, the RD-300-CR integrates power management (solar controller, rechargeable battery), data acquisition/transmission, and seamless expansion for external devices (cameras, rain gauges, water quality sensors, micro weather stations). It collects all parameters, combines them with water level data, and uploads monitoring data and images to cloud servers via protocols such as SL651, SZY206, HJ212, MQTT, or custom standards.

Remote Management Platform
A centralized cloud-based platform enables real-time device management, on-site visualization, data aggregation, and mobile APP access for grid-based, informatized management. The system is scalable to accommodate additional parameters or control functions as needed.
