The M21F-V50 Telemetry Terminal integrates the functions of a traditional hydrological telemetry terminal, wireless long-distance transmission via 2G/3G/4G full-network compatibility and NB-IoT short message, and wireless short-distance transmission via LoRa. It delivers comprehensive capabilities including data collection, storage, transmission, display, control, and alarm for hydrology, water resources, geological disaster monitoring, and meteorology.
Equipped with a high-performance industrial-grade 32-bit communication processor, it provides a complete set of interfaces: tipping bucket rain gauge, RS232, RS485, SDI, Ethernet, 4~20mA, 0~5V analog inputs, digital I/O, and relay outputs.
Water conservancy informatization, hydrology measurement, water environment monitoring, flash flood disaster prevention, reservoir and dam safety monitoring.
