Small and compact, short-range current profiling; option for PUV wave measurements
Highlights
- Up to 10 m current profiling range
- Optional right-angle head
- PUV-based directional wave measurements
Overview
- The Aquadopp Profiler is a highly versatile Acoustic Doppler Current Profiler (ADCP) available in four profiling range options, from < 1 m to > 85 m. Designed for simple yet powerful operation, this current profiler is packed with features used by engineers and researchers to enable accurate and effective hydrodynamic data collection in a variety of environmental conditions.
Applications
- Near-bed current profiles with fine vertical resolution
- Mean flow measurements with high focus on ease of use and simplicity
- Measurements in flow regimes with strong variations in flow speeds
- Projects with needs for both high-resolution and normal-range current measurements
- Measurements of combinations of waves and currents
- Studies of deep-water currents
- Studies of tidal currents
- Mounted on surface buoys
- Suitable for wave buoys
