The Vector 3D current meter collects high-resolution velocity and pressure data in rapidly changing environments. Based on processing schemes originally developed for the Nortek Acoustic Doppler Velocimeter, the system electronics integrates unique Doppler velocity measurements with standard sensors such as temperature, pressure, tilt, and compass. State-of-the-art power management and miniaturized electronics combine in a compact single-canister design that is suitable for real time operation or self-contained deployments.
In addition to continuous sampling the Vector also supports burst sampling, where data are sampled rapidly for a short period of time before it "sleeps" to preserve battery power and recorder memory. Pressure is measured at the same rate as the 3D velocity. All other sensors are sampled at 1 Hz.
The Vector comes with a complete suite of Windows® 2000/XP software for deployment planning, real time data collection and data retrieval. As an option, the post processing program ExploreV is available to review, process and interpret your Vector data. The processing includes spectral analysis, coordinate transforms, and calculation of complex turbulence parameters.
The Vector is designed with turbulence and wave measurements in mind. Typical applications include wave orbital studies at bottom boundary layers, ocean engineering, coastal studies, river turbulence, etc. In addition, the Vector is used whenever a distinct and small sampling volume is required. The water quality is of little importance as long as there are enough particles in the water - the Vector works equally well in typical ocean surface water and in the high sediment suspensions found near the coast or in rivers.
The system response when submerged is near instantaneous, making wave crest measurement possible as the probe moves in and out of the water. Nortek shipped the first Vectors in 1999. Today, it is being used by scientists and engineers at renown oceanographic institutions worldwide.
