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 version is suitable for use down to a depth of 300 m. The Vector’s titanium version is suitable for investigating deep- water currents.

Setup
This 300m-rated velocimeter is set up using the Nortek deployment software, where users can customize the sampling rate (up to 64Hz), sampling volume size and coordinate system, especially relevant the cabled probe option.
Deployment
Designed for small-scale turbulence sampling or collecting measurements near boundaries, the Vector velocimeter offers multiple probe options (fixed or cabled) making for very flexible deployment setups.
Data
The Vector provides precise, rapid velocity measurements from a very small sampling volume of water. Users can resolve small-scale turbulence events and measure in areas traditionally difficult for ADCPs.
