SonTek’s ADV (Acoustic Doppler Current Meter) gauging equipment is a high performance system. In hydrology, ADVs are used as the classic windlasses in gauging by wading (or operated by means of bars from a gangway).

By using ADV it is possible to know the value, at the moment, of the flow rate through a section, as well as other parameters of special interest such as the area, velocity distribution, as well as the angles and temperature of the flow.

  • The Flowtracker2 has a high precision sensor.
  • 2-D data in the horizontal plane (2D / 3D option available).
  • No user calibration is required.
  • Integrated GPS for georeferencing with automatic or manual corrections.
  • Battery life icon on the display at all times. Possibility to pre-charge the spare battery cartridge and replace, even during the measurement, without loss of data.
  • Detachable probe with extension cables to customize cable lengths up to 10m
  • Probes and electronic unit are interchangeable
  • Direct USB connection to PC or Bluetooth
  • Audio messages
  • Set up and save templates without the need to re-enter data each time you visit a gauging point
  • Open source JSON format compatible with direct import into Hydstra, Aquarius, WISKI, etc…
  • Specific for direct flow gauging by fording or from a footbridge.
