16-MHz MicroADV

16MHz ADV - Israel

16MHz ADV - MIT Lab

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.

Flume Measurements with the MicroADV

Flume Measurements with the MicroADV

A research group from the hydraulic laboratory at Wuhan University of Hydraulic and Electric Engineering (Wuhan, China) used several SonTek/YSI MicroADV lab systems to measure turbulence and mean flow over the water column of a flume. The photo shows the MicroADV probe and its setup platform. The research group was particularly interested in the measurements close to the bottom, and was very pleased with the MicroADV's performance.
