SonTek 10-MHz ADV®

Product discontinued. Please refer to other Velocity & Flow Meters.

The SonTek ADV is a single point, high resolution Doppler current meter which provides 3-D velocity measurements in a remotely sampled volume. The ADV is a bistatic Doppler current meter. The term bistatic refers to the fact that the ADV uses separate acoustic transducers to transmit and receive sound energy. The ADV transmitter generates sound with most of the energy concentrated in a tight cylindrical volume, while the receivers are the most sensitive to sound coming from a slightly broader angular range. The transducers are mounted such that their beams intersect over a volume located some distance away, called sampling volume. This document presents a basic description of the effects of the finite sampling volume on the accuracy of the velocity measurements.

SonTek 16-MHz MicroADV

Product discontinued. Please refer to other Velocity & Flow Meters.

The SonTek 16-MHz MicroADV (Acoustic Doppler Velocimeter) is the most significant breakthrough in 3-axis (3D) current meter technology since the original SonTek ADV. The original SonTek ADV has compared favorably with Laser systems costing ten times as much — the MicroADV fares even better. The higher acoustical frequency of 16 MHz makes the MicroADV the optimal instrument for laboratory work. Like all SonTek instruments, the MicroADV is extremely simple to set up and use. Most users are taking high-quality data within minutes of receiving the system.
