Vector ultrasonic Doppler 3D single-point flow direction and velocity meter
Vector
A high-speed sampling (up to 64Hz) ultrasonic three-dimensional flow direction and velocity meter that focuses on a single point. It can be used from deep sea depths of 6000m to indoor experimental tanks.
The Vector is a high-precision single-point flow direction and velocity meter that can be set to a sampling frequency of up to 64 Hz. To perform remote flow direction and velocity measurements using ultrasound, it is not necessary to place sensors within the measurement area. Measurements can be taken without disturbing the flow conditions in the target area. It is particularly effective for measuring flows in complex situations, such as those occurring behind structures, in breaking wave zones, and near the seabed, where measurements are difficult with ADCPs. There is also a deep-sea version of the Vector with a titanium pressure-resistant housing that can withstand depths of 6000 meters. It can be used in various environments, from field marine areas to flow measurements in hydraulic experiment tanks.
