Overview

The Vector is a high-accuracy single-point current meter that is capable of acquiring 3D velocity in a very small volume at rates up to 64 Hz. It is widely used for sediment transport applications, small-scale turbulence measurements and coastal engineering studies. It has an excellent track record of delivering outstanding data quality in a variety of applications. This titanium version of the Vector is suitable for investigating deep-water currents down to depths of 4000 m.

Highlights

Small-scale turbulence
Sampling up to 64 Hz
Small sampling volume for measurements close to boundaries

Applications

Studies of bottom boundary layers
Studies of deep-water currents
Ocean engineering projects
Low flow measurements
Flux measurements
Deep ocean mining support
