Founded in 1992 on the premise that precision water velocity mea- surement should be practical, af-fordable, and easy, SonTek today offers a wide variety of acoustic Doppler instrumentation. Sim-ply put, its instruments use sound waves to tell the user how fast wa- ter is moving, where it is moving, and even if it is moving at all. Cus- tomers are scientists, engineers, hydrologists, research associates, water resource planners and anyone that needs to collect ve- locity (speed) data in every kind of body of water imagin- able. SonTek is now a part of Xylem, a leading provider of ß uid technology and equipment solutions for the planetÕs most challenging water issues. The 10-MHz Acoustic Doppler Ve- locimeter (ADV), was developed in cooperation with the US Army Corps of EngineersÕ Waterways Experiment Station. Originally designed for laboratory use, the ADV is a single- point, high-resolution Doppler current meter used for detailed studies of 3D velocity Þ elds. Since its introduction, the ADV has become established as the standard for high-resolution velocity data. The ADV product line includes laboratory and Þ eld instruments with options for integrated sensors and au- tonomous operation. The Acoustic Doppler ProÞ ler (ADP) is a current proÞ ler with proÞ ling ranges of up to 200 m. The ADP revolutionized the market for current proÞ lers. SonTek later re- Þ ned current proÞ ling by introducing the Pulse-Coherent ADP (PCADP) Ð one of the highest resolution acoustic Doppler cur- rent proÞ lers available. W ith the introduction of the Argonaut- MD, SonTek produced a new level in user-friendly, low-power Doppler current meters. The Argonaut line expanded to include the Argonaut-SL and Argonaut-XR for hydrological and har- bor monitoring applications and the Argonaut-ADV for single point measurements where power is limited. onTek recently released the award-winning, multi-frequency RiverSurveyor. This highly accurate ADP is designed to measure 3D water currents and depths from a moving or stationary boat.
