SonTek FlowTracker2 Lab ADV®

SonTek FlowTracker2 Lab ADV®

For decades, the Acoustic Doppler Velocimeter (ADV®) has been the preferred instrument for precisely-defined sampling of water velocity across a wide range of environments. 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.

  • Features
  • Let's Get Started!
  • Optional Handheld System


• Civil engineering, environmental, and hydraulic projects
• Aquaculture and aquarium operations
• Surface and bottom boundary studies
• Tanks, flumes, and physical models
• Very shallow water environments
• Turbulence
• Settling rates
• Fish screens

Depth data are 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 are output directly to a *.CSV file that is immediately ready for use in the project, model, or database as required.

The SonTek ADV is a longtime standard for accurate, high-precision water velocity measurements under a wide variety of flow conditions and research settings.

Output Variables Available

• Velocity X, Y, and Z¹
• Per beam (2 or 3 parameters, depending on probe configuration)
- Correlation score
- Signal-to-Noise Ratio (SNR)
- Signal amplitude
- Noise level
• Pressure sensor calibration interval
• Temperature
• Sound speed
• Raw pressure²
• Corrected pressure²
• Depth²
• Power voltage
• Accelerometer X, Y, and Z

¹ Z (vertical) velocity available with optional 2D/3D probe configuration
² Pressure and depth available with optional probe configuration

In three simple steps, the FlowTracker2 Lab ADV delivers robust, high-quality data right out of the box. The software interface writes data directly to a *.CSV file which can then be further processed, analyzed, or imported into other programs according to your project needs.
