  SonTek Water Velocity Measurement

FlowTracker Handheld ADV

The SonTek/YSI FlowTracker Handheld ADV (Acoustic Doppler Velocimeter) uses our proven ADV technology in a compact, hand-held package to make accurate, high-precision 2-axis (2D) or 3-axis (3D) water velocity measurements in natural streams, weirs/flumes, and open channels related to irrigation, storm water, water treatment, and mining. Designed with the field user in mind, the FlowTracker easily attaches to top-setting wading rods and features an automatic discharge computation program that is based on USGS/ISO methods.

Features and Benefits:

  • Simple hand-held interface with real-time velocity display

  • Automatic discharge computation program based on USGS/ISO methods

  • Shallow-water 2-axis (2D) probe measures in depths as little as 2 cm (~1 in.);

  • optional 2D/3D probe is available.

  • 2-m probe cable (5-m cable optional- see below update)

  • Remote sampling volume of 0.25 cm3 located 10 cm from the transducer

  • FlowTracker software package

  • Internal memory for 80,000 measurements (non-volatile)

  • Temperature sensor

  • Built-in recorder, battery power, and RS232 interface

  • Mounting pin on ADV probe (Note: Complete mounting brackets for top-setting wading rods are available.)

  • Optional Wading Rod Kit

  • Velocity range: ± 0.001 m/s to 4.5 m/s (0.003 to 15 ft/s)

  • Resolution: 0.0001 m/s

  • Accuracy: ±1% of measured velocity, ±0.001 m/s

  • No periodic recalibration required - invariant factory calibration

  • Proven SonTek reliability

  • Output compatible with FlowPack velocity-indexing software tool

Update! Starting in March 2008, SonTek will begin replacing our 3-m cable option with a 5-m cable option. Our 2-m cable will remain the standard length. Note that there are some caveats if you choose to use a 5-m cable instead of the standard 2-m cable.

new 5m cable option.
