SonTek ADV Acoustic Doppler Velocimeter is a standard velocity measuring instrument for hydraulic and marine laboratories

16MHz MicroADVUsed for laboratory average flow velocity, boundary layer flow velocity, turbulent flow (Reynolds stress), and wave spectrum measurement. less than0.09A sampling volume of cubic centimeters and up to50Hertz's sampling frequency is an ideal laboratory instrument for studying low flow velocity and turbulence.

On site acoustic Doppler flowmeter
10MHz ADVUsed for on-site average flow velocity and turbulence (Reynolds stress) measurement, it is suitable for both laboratory and field measurements, with strong adaptability and reliability.

Marine Acoustic Doppler Velocimeter
ADV OceanUsed for measuring the seabed boundary layer of ocean currents, on-site wave spectra, and turbulent flow (Reynolds stress) in fragmented wave areas. The hard shell and professional design makeADV OceanBecoming an ideal instrument for measuring flow in harsh environments.

ADVThere are three frequencies:16MHzThe10MHzThe5MHzThe main technical indicators are as follows:

ADVThere are four forms of probes: three-dimensional-Top view, 3D-Side view, 3D-Looking up, 2D-Side view, the distance between the measuring unit (and measuring point) and the probe can be5Centimeters or10Centimeters. two-dimensional-Side view probe can be used for situations with extremely shallow water depth（2-3Centimeters).
