Vector - 300 m

Sample 3D velocity at up to 64 Hz for small-scale research in coastal areas

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 turbulencemeasurements and coastal engineering studies. It has an excellent track record of delivering outstanding data
quality in a variety of applications. This version is suitable for use down to a depth of 300 m. The Vector’s titanium
version is suitable for investigating deep- water currents.
