Non-contact, high-precision flow measurement | Radar Doppler velocity and discharge sensor—empowering intelligent hydrological monitoring of rivers and channels!
2026-06-15
For hydrological monitoring applications such as natural rivers, artificial channels, and municipal stormwater drainage ditches, the radar Doppler flow‑velocity and discharge sensor leverages advanced radar Doppler measurement technology to deliver truly non‑contact, all‑weather, high‑precision flow measurement. It effectively addresses the challenges of conventional contact‑type flow‑measurement devices, including cable entanglement, clogging, and frequent maintenance.
The device leverages the Doppler radar frequency‑shift principle to remotely measure surface water velocity and water level, then employs built-in algorithms to compute real‑time discharge. It operates without any contact with the water body and is unaffected by sediment, aquatic vegetation, or floating debris, making it well suited for complex operating conditions such as flash floods, high‑water levels during flood season, and low‑flow shallow streams. Measurement data are stable and highly accurate.
The device features a compact design and easy installation, with an IP67‑rated enclosure that provides high‑level protection against water and dust. It is resistant to extreme temperatures and weathering, enabling 24/7 unattended operation in outdoor environments. Equipped with a wireless transmission module, it can upload real-time data on flow velocity, water level, and discharge to a cloud platform, supporting remote monitoring, data archiving, and flood‑warning alerts.
This device is widely applicable to scenarios such as river‑channel runoff monitoring, irrigation‑district water‑quantity measurement, flood‑discharge‑channel flow monitoring, and mountain‑runoff hydrological forecasting. With its non‑contact operation, high stability, and maintenance‑free design, it comprehensively enhances the precision of hydrological monitoring, providing reliable data support for water‑resource allocation, flood prevention and disaster mitigation, and watershed management.
