Acoustic Doppler Velocity

The Handheld Acoustic Doppler Velocimeter (ADV) measures 2D or 3D currents, attaches easily to wading rods, and features an automatic discharge computation using a variety of international methods, including ISO and USGS standards.


  • Proven velocity accuracy to as low as 0.001m/s (0.003 ft/s) and up to 4.0 m/s (13 ft/s)
  • Record changing gauge heights and rated flows, with comments Automatic discharge uncertainty calculation to ISO standard.
  • Measure velocities in water as shallow as 2 cm (less than an 1 inch)
  • Keypad interface with real-time velocity and flow display
  • Automatic quality control for accurate data collection
  • Two or three dimensional velocity measurement
  • Recorded data is shielded from power loss
  • No calibration required – ever!
  • Built-in temperature sensor
