Acoustic Doppler System

Acoustic Side Looking Doppler System

AcousticSide-LookingDopplerSystemFlow mechanics when it’s getting turbid.
The Acoustic Side Looking Doppler System is an excellent alternative for measuring flow velocities in turbid flows where light-based techniques reach their limitations. Using the Doppler effect, the system provides velocity profiles consisting of nine 2D velocity vectors.
