Radar Flow Meter for Open Channels, Rivers & Pipes | Frankstar
FS-LDLL-001 Radar Flow Meter is a sensor designed for measuring water surface velocity and flow in open water bodies. The ranging radar unit adopts FMCW (Frequency-Modulated Continuous Wave) technology, while the velocity radar operates at 24 GHz. The measurement point is located in front of the device, ensuring non-intrusive measurement without disturbing the flow field, resulting in high accuracy and excellent linearity.
With no moving parts, the sensor is resistant to sediment blockage, aquatic vegetation interference, and debris entanglement. The robust probe design ensures reliable long-term operation in harsh environments, including rivers with high sediment concentration, abundant floating vegetation, and severe winter icing conditions.
This radar flow meter is widely used for flow monitoring in hydrological stations, irrigation secondary channels, stormwater and wastewater pipe networks, and natural rivers.

Radar Water Level & Velocity Station – Non-Contact Water Level and Surface Velocity Monitoring System
Frankstar Radar Level Velocity Station adopts non-contact radar measurement technology to achieve high-precision, all-weather and automatic water level data collection for rivers, channels and other water bodies. It effectively overcomes the drawbacks of traditional contact sensors, such as siltation, icing, floating debris impact and biological fouling, ensuring long-term reliable data.
Integrated with a positioning system, 4G/5G communication and a high-efficiency solar power supply system, the Station enables long-term unattended operation in remote field environments without mains power or network coverage, greatly reducing operation and maintenance costs. Collected data is transmitted in real time to the monitoring center or cloud platform, providing a scientific basis for flood control, disaster mitigation, water resource management and ecological protection, while significantly improving emergency response efficiency and the safety of water conservancy facilities.
