Aquadopp Profiler 1 MHz - 500m, Z-Cell,
Generation 2

Up to 25 m current profiling range and no blanking; can measure nearsurface or near-bottom currents

Need to collect accurate 3D currents very near the seabed or sea surface, in addition to a full water-column
profile?
The Z-Cell (Zero Cell) 1 MHz Aquadopp allows current measurement to start right at the instrument’s level throughan innovative approach: it has side-looking beams fully integrated into the instrument’s head, effectively
removing the blanking distance normally applicable to ADCPs. The 1 MHz Z-Cell profiler also offers all of thefeatures and capabilities of the 1 MHz Aquadopp Profiler.

See the details of the Generation 2 Aquadopp updates in the release notes here.

Highlights
Up to 25 m current profiling range
Capable of measuring surface or bottom
currents
PUV-based directional wave measurements

Applications
Mounted on bottom frames, with ability toalso measure near-bed currents
Mounted on surface buoys, with the ability
to measure also surface currents
Mean flow measurements with high focus onease of use and simplicity
Measurements of combinations of waves
and currents
