- ADCP Acoustic Doppler Current Profiler (Small Beam Range)
◆ Measurement principle
ADCP stands for Acoustic Doppler Current Profiler. It is an instrument used to measure water flow velocity. Utilizing the acoustic Doppler principle, it emits sound waves into the water body and then receives the reflected sound wave signals from suspended particles and other objects in the water. By analyzing the Doppler frequency shift, it calculates the flow velocities of different water layers.
◆ Main features
▶ Measurement parameters: stratified flow velocity, average flow velocity, water level, flow rate, cross-sectional area of flow, water temperature, and cumulative flow volume.
▶ Bidirectional flow (bidirectional model): Identifies forward and reverse flows, outputs values with positive and negative signs, ranging from -10 to 10 m/s;
▶ Number of slice layers: 256 layers;
▶ Two sets of underwater ultrasonic transducers;
▶ Alloy plastic casing;
▶ Continuous acoustic pulse output;
▶ Static-pressure water level sensor (with built-in flow rate dynamic pressure compensation) and conductivity sensor;
▶ Installation method: H-ADCP—side-mounted, side-sweep type; V-ADCP—bottom-mounted, upward-sweep type; compact size and streamlined design.
▶ IP68 protection rating;
▶ Awards: Multiple patents and software copyrights;

Application scenarios
Measurement of flow velocity and discharge in urban rivers, channels, and discharge outlets.
It can rapidly and accurately measure flow velocity information without disrupting the structure of the water flow, and it is capable of conducting measurements over a wide range of aquatic environments, including rivers, oceans, and other bodies of water. This technology finds extensive applications in numerous fields such as hydraulic engineering, oceanographic research, and water environment monitoring. For instance, it plays a crucial role in studying river hydrological characteristics, monitoring floods, and assessing water flow conditions at ports.
