The HB400 Water Level Meter is a cutting-edge water level monitoring device developed using satellite interferometric remote sensing technology for water level inversion. It features high spatial and temporal resolution, a wide range of signal sources, and does not require direct contact with water for installation and operation. This makes it highly suitable for monitoring water levels in rivers, lakes, reservoirs, and other water bodies, especially in areas with complex terrain or large-scale water areas. The device is particularly effective for emergency flood monitoring, as it can be easily deployed along embankments to accurately measure water levels and transmit data via wireless networks or BeiDou short messages.

• High Measurement Accuracy: Water level measurement accuracy ≤ 2cm

• Multiple Communication Options: Supports LoRa, WiFi, RS485 bus, fiber optics, 4G, and BeiDou short messages

• External Sensor Support: Compatible with RS485 Modbus protocol sensors, providing power and network connectivity for the sensors

• Autonomous Front-End Calculation: The device includes an embedded calculation engine, enabling it to perform real-time water level calculations. The results are directly integrated into the RTU/monitoring platform

• High Reliability: IP68 protection rating with a Mean Time Between Failures (MTBF) of ≥ 35,000 hours

• Large Capacity Battery: Equipped with a high-capacity internal battery, providing autonomous 24-hour operation. It also supports external power supply options
