SONTEK Model FlowTracker2 ADV Handheld Acoustic Doppler Velocimeter

The SonTek FlowTracker 2 (FT2) handheld Acoustic Doppler Velocimeter (ADV®) is a wading discharge measurement instrument that is handheld, portable and precise.
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 FT2 guides you along the measurement process with visual prompts and SmartQC audio alerts just in case something important needs your attention. FT2 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, FT2 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

At its core, FT2 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 FT2, the acoustic-based ADV sensor offers unparalleled accuracy, particularly in low flow, and in the shallowest water of any wading device.  2-D data in the horizontal plane (2D/3D option available) allows the most comprehensive QC and understanding about flow conditions.  User calibration is never required, and 24/7 tech support from SonTek and our worldwide team is only a call or click away.
Some of the major improvements now featured in FT2 come straight from field users like you. Here is a short list of time-saving, fool-proof features:

FT2 battery compartment is now
easy to access in the field:
NO TOOLS REQUIRED!
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, 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 direct USB interface with PC
Audio prompts
