Flow Tracker 2 Handheld-ADV

The SonTek FlowTracker2 handheld Acoustic Doppler Velocimeter (ADV®) is a handheld, portable, and precise wading discharge measurement instrument.

We know our users love and trust the technology with the original FlowTracker, but we wanted more! The FlowTracker2 now comes with functional, modernized features such as Bluetooth, GPS, and a large color screen, to name only a few. The enhancements came directly from the evaluation and feedback from hydrologists, researchers, and scientists who have made the FlowTracker their instrument of choice.

Portable. Precise. Practical.

The real advantage becomes clear from the moment you start to collect data. Each step of the way, FlowTracker2 guides you along the measurement process with visual prompts and SmartQC audio alerts just in case something important needs your attention. FlowTracker2 handheld software is intuitive, easy to navigate, and includes real-time plots of point data, QC parameters, and measurement verticals, giving you everything you need at-a-glance. Get defensible data correctly, the first time, every time, and minimize data handling back at the office.

Whenever and Wherever You Need

With rugged construction for any climate and multiple display options for both day and night, FlowTracker2 goes whenever and wherever you need it to go. This includes:

  • Natural Streams, Open Channels & Lakes
  • Irrigation Canals
  • Mining Channels
  • Water Treatment
  • Storm Water
  • Weirs / Flumes

FlowTracker2 uses SonTek’s tried-and-true ADV technology, vetted for decades by experts across the globe in hydraulics labs and wide-ranging field environments. Improved and perfected for FlowTracker2, the acoustic-based ADV sensor offers unparalleled accuracy, particularly in low flow and any wading device's shallowest water. 2-D data in the horizontal plane (2D/3D option available) allows the most comprehensive QC and understanding of flow conditions. User calibration is never required, and 24/7 tech support from SonTek and our worldwide team is only a call away.

Some of the major improvements featured in FlowTracker2 come straight from field users like you. Here is a shortlist of time-saving, fool-proof features:

  • Embedded GPS for georeferencing with automatic or manual fixes
  • Improved ADV acoustics: faster pinging, lower noise, and better standard error
  • Battery life icon on the screen at all times.  Pre-load the spare cartridge and replace it, even mid-measurement, with no data loss
  • Detachable probe with extension cables to customize cable length up to 10m
  • Probes and handhelds are interchangeable—flexibility within agency teams and when sending equipment for service
  • Set up and save templates—no need to re-enter data every time you visit a site
  • Bluetooth or a direct USB interface with a PC
  • Audio prompts

There is a lot to get excited about when using the new FlowTracker2 handheld. Intuitive workflow and rich graphics make for a modernized, interactive experience. Now you can:

  • Rely on FlowTracker2 to automatically conform to proper methods based on depth
  • View beam check or QC plots directly - know immediately if you have signal or beam blockage problems
  • Get real-time plots of velocity and other parameters
  • Enter comments and gage heights with any station
  • View a running discharge summary
  • See an image of a top-set wading rod
  • View an on-screen tilt sensor
  • Edit data
