Advanced Acoustic Doppler Velocimeters for Precision Flow
High-resolution 3D water velocity measurement tools tailored for scientific, industrial, and environmental applications.
Advanced Flow Characterization with Acoustic Doppler Velocimeters
Acoustic Doppler Velocimeters (ADVs) are high-precision instruments designed to measure three-dimensional water flow velocities at a single point using the Doppler shift principle. Widely used in laboratory research and field studies, ADVs provide critical data for hydrodynamic modeling, sediment transport analysis, and turbulence monitoring. These systems offer unmatched resolution and accuracy in low and high-flow conditions, even in environments with suspended solids or complex geometries.
Water Quality Instruments brings advanced ADV technologies to B2B clients across North America, helping researchers, engineers, and facility operators gain better insights into water movement and system dynamics. Our sensor systems are trusted for their durability, performance, and seamless integration with data acquisition and control platforms.
