Aquadopp Profiler 2 - 400 kHz

Avec une portée de mesure jusqu'à 90 m. Idéal pour les applications
nécessitant le courant moyen.

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 ina variety of environmental conditions.

Highlights
Up to 90 m current profiling range
Ideal for mean current measurements
Easy to operate and deploy

Applications
Mean flow measurements with high focus onease of use and simplicity
Measurements in flow regimes with strong
variations in flow speeds
Studies of tidal currents
Measurements of combinations of waves
and currents
Mounted on surface buoys
Suitable for wave buoys
