Description of the Nortek Aquadopp:
The Nortek Aquadopp works by sending acoustic waves into the water and measuring the frequency shift of the reflected waves caused by moving water particles. This frequency shift allows the device to calculate the speed of water particles, which in turn helps determine the velocity and vertical profile of the water flow. It is highly valuable for obtaining accurate data on the movement of water, including current velocities and turbulence at different depths.
