Acoustic Doppler Velocimeter (ADV)
The Acoustic Doppler Velocimeter (ADV) is a tool that is designed to record instantaneous velocity components at a single-point with a relatively high frequency. The measurements are performed by measuring the velocity of particles in a remote sampling volume. It consists of a probe head made of 3 to 4 receivers. The measuring distance can be anywhere between 5 and 15 centimeters from the probe head.
