Aquadopp Profiler 2 - 2 MHz

Petit et compact, pour les applications nécessitant une portée de mesurecourte. Mesure de la houle par PUV en option.

The Aquadopp Profiler is a highly versatile Acoustic Doppler Current Profiler (ADCP) available in four profiling
range options, from < 1 m to > 85 m. The 2 MHz version has a current profiling range of up to 10 m. Designed forsimple yet powerful operation, this current profiler is packed with features used by engineers and researchers toenable accurate and effective hydrodynamic data collection in a variety of environmental conditions.

Highlights
Up to 10 m current profiling range
Optional right-angle headPUV-based directional wave measurements

Applications
Near-bed current profiles with fine verticalresolution
Mean flow measurements with high focus onease 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
