SonTek FlowTracker 2 LAB

The FlowTracker2 Lab ADV utilizes SonTek’s continuing innovation in ADV platforms to offer a laboratory version of the world’s best-selling ADV, the FlowTracker2. For the first time, the ADV’s acoustic probe and processing electronics are housed in one small, lightweight, easily- maneuverable unit, and the acoustic head has an optional, integrated pressure (depth) sensor.

Depth data is even correctable for dynamic pressure (Bernoulli) and altitude effects using SonTek’s patent-pending method. Setup of the probe and PC software is simple and mistake-proof. Just connect the cables between the probe and your laboratory PC or laptop, check a few settings, and press the “Start Logging” button. Data is output directly to a *.CSV file that is immediately ready for use in the project, model, or database as required.
