Radar Flow Meter | Reliable Open Channel Flow Measurement | 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.

Magnetostrictive Weir Flow Meter – High-Precision Open Channel Flow Measurement and Water Level Monitoring
The FS-LSYJ-001 magnetostrictive weir flow meter is designed for long-term water level monitoring in rivers, lakes, reservoirs, and dam weir structures. It is an effective device for monitoring water level and flow variations.
The instrument uses a magnetostrictive liquid level sensor for measurement, featuring high resolution, excellent stability, reliable performance, fast response, and long service life.
Key features include linear measurement, absolute position output, contact-type continuous measurement, and non-wearing operation. The sensor requires no calibration or routine maintenance. Multiple output signals are available (RS485, voltage, current), and the device is easy to install.
