Single Point Velocity Meter

The Single Point Velocity Meters (Nortek Aquadopp® instruments) use acoustic Doppler technology to measure the mean velocity (speed and direction) of water in two-dimensions (U & V) as it moves past the sensor. VELPT instruments are mounted on stationary moorings, seafloor platforms, and wire-following profilers across multiple OOI arrays.
