The HB400 Water Level Meter is an innovative monitoring device that utilizes satellite interferometric remote sensing technology for water level retrieval. It offers high spatiotemporal resolution and leverages abundant signal sources, enabling installation and operation without direct water contact. Suitable for rivers, lakes, reservoirs, and various other water bodies, it is particularly ideal for monitoring complex terrains and large-area water surfaces. During flood emergencies, its flexible deployment allows for accurate water level measurement from riverbanks or embankments, with data transmitted via wireless networks or BeiDou short message service.
In areas without public network coverage, water level calculation results can be transmitted to the data center via BeiDou-3 short message service.
