The automatic water level station is constructed in a management mode of unmanned and supervised operation. Configure water level sensors, telemetry terminals (RTUs), communication terminals, power systems, lightning protection systems (lightning rods, down conductors, lightning grounding wires, etc.) to achieve automatic collection and remote transmission of water and rain information.
Product Features
1) Adopting an integrated design, it is easy to install, highly reliable, and easy to use and maintain. The center can configure various parameters and receive data in real time;
2) Equipped with intelligent collection of water level and rainfall data, long-term solid-state storage, and long-distance transmission functions;
3) Support three communication methods: self reporting, self reporting confirmation, and call response. The three communication methods can be mixed for networking;
4) Real time monitoring of equipment power supply voltage, working environment temperature, and system status information;
5) Flood reporting requirements: Adopt regular and incremental reporting methods, and set the reported water level amplitude based on the characteristics of the river and the fluctuation of water level.
6) Warning function: The station is located upstream of the village and can calculate water level warning indicators for downstream villages; The station is located at the outlet of the watershed and can calculate or verify the rainfall warning indicators of small watersheds.
