272 JOURNAL OF ATMOSPHERIC AND OCEANIC TECHNOLOGY VOLUME 15 q 1998 American Meteorological Society Evaluation of the Acoustic Doppler Velocimeter (ADV) for Turbulence Measurements*
SonTek, founded in 1992 and advancing environmental science in over 100 countries, manufactures reliable acoustic Doppler instrumentation for water velocity measurement in oceans, rivers, lakes, harbors, estuaries, and laboratories.
A new method for detecting spikes in acoustic Doppler velocimeter data sequences is suggested. The method combines three concepts: (1) that differentiation enhances the high frequency portion of a signal, (2) that the expected maximum of a random series is given by the Universal threshold, and (3.
The SonTek/YSI FlowTracker Handheld ADV is a compact, hand-held package to make accurate, high-precision water velocity measurements in natural.

Armed with a fresh product demo from manufacturers in China, the execs started to feel out major companies that might want to buy Doppler Labs. They declined to tell Wired how much they were asking, but it was a lot. “We thought we.
Acoustic Doppler velocimetry (ADV) is designed to record instantaneous velocity components at a single-point with a relatively high frequency. Measurements are performed by measuring the velocity of particles in a remote sampling volume based upon the Doppler shift effect.
1. How velocimeters work. The Acoustic Doppler Velocimeter is a versatile, high-precision instrument that measures all three flow velocity components.
SonTek, founded in 1992 and advancing environmental science in over 100 countries, manufactures reliable acoustic Doppler instrumentation for water velocity measurement in oceans, rivers, lakes, harbors, estuaries, and laboratories. SonTek is headquartered in San Diego, California, and is a brand of Xylem Inc.
