When performance matters in current measurements

This all-new single-point 3D current meter provides you with high-resolution current information from all open water applications. 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 long-term self-contained deployments.

The Vector is designed with turbulence and wave measurements tin mind, but it also works as a standard current meter.

Rapid sampling rate resolves typical open water turbulence. The non-intrusive acoustic measurement suits it for wave orbital velocity, bottom boundary layer studies, ocean surface studies, coastal studies, etc.

The water quality is of little importance. The Vector works equally well in typical ocean water and in 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.

The Vector supports burst sampling, where data are sampled rapidly for a short period of time before it "sleeps" to preserve battery power and recorder memory. The Vector samples pressure and temperature at the same time as the 3D velocity.

The Vector comes with a complete suite of Window 95/98/NT software for deployment planning, real time data collection and data retrieval.

Explore Acoustic Doppler Velocimeter, a post-processing program for spectral analysis and calculation of complex turbulence parameters, enables you to quickly see, process and interpret your turbulence data.

You can obtain the Vector with two different probes: a cable probe with 2-m cable and a rigid probe with a 25 cm stem (picture). The cable probe must be aligned with the main housing to ensure proper orientation.
