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.
