View source for Acoustic doppler velocimeter

{{GlossaryEntry
|definition=A device used to make ultrasonic measurements of flow velocities. ADVs are smaller than [[Acoustic Doppler Current Profiler|ADCPs]] and are used both for field and laboratory measurements. Contrary to ADCPs the measuring beams concentrate on a single spot (i.e. a very small measurement volume), thus immediately delivering results for this particular spot.
