Radar Flow Meter – Non-Contact Flow Measurement System for Open Channel and River Flow Monitoring
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.

Float-Operated Water Level Gauge – Mechanical Water Level Measurement and Monitoring Instrument for Hydrological Applications
FS-LDSW-001 Float-Operated Water Level Gauge is a digital sensor integrating mechanical and electrical technologies. It converts the angular displacement of the output shaft into digital signals, enabling high-precision measurement of water level and determination of absolute position. The device features a power-off memory function.
Its working principle is as follows: the measuring wheel of the water level sensor is mounted on the encoder input shaft. A steel wire rope connects the float at one end and a counterweight at the other, winding around the measuring wheel. When the water level changes, the float rises or falls accordingly, driving the wire rope and rotating the measuring wheel. The encoder then outputs real-time water level values.
The device is widely used for water level monitoring in rivers, lakes, reservoirs, ship locks, hydropower stations, hydrological stations, water treatment plants, and petrochemical facilities, as well as for both surface water and groundwater level measurement.
