3-D Single Point Velocity Meter
The 3-D Single Point Velocity Meter (VEL3D) measures the fluctuating velocity (speed and direction) of water moving past the sensor and platform motion on moving profilers in three-dimensions (u,v,w). The VEL3D turbulent flow current meter measures how seawater mixes at the small scale, which is important in understanding how heat, mass, and momentum are transported throughout the ocean. When deployed in conjunction with nearby acoustic instruments, current meters can also provide important data for filtering of local current “noise” out of the acoustic signal.
