velocimeter
[ vē′lō-sĭm′ĭ-tər, vĕl′ō- ]
A device that utilizes the Doppler effect to measure the speed of sound in water. Developed by the US Army Corps of Engineers, a velocimeter transmits a pulse of sound through water and measures its echo for changes in either pitch or frequency. Oceanographers employ velocimeters to study the interior structure of breaking waves; they are also used in hydraulic engineering and to study fluid flow.
