WTW flow and profilometer RiverSurveyor® ADCP M9
.
RiverSurveyor®: The turnkey solution for all mobile flow measurement challenges - stable and continuous measurement
  • Fast setup and start of data acquisition
  • No manual programming required: Automated pulse & frequency selection
  • No loss of data when the radio link is interrupted: Measurement directly in the measuring device
  • Safe determination even at high water and high flow rates

The RiverSurveyor® is a rugged and high-precision ADCP (Acoustic Doppler Current Profiler) for mobile acquisition of surface water flow rate and flow. An outstanding feature of the RiverSurveyor® is the use of multiple ultrasonic frequencies with precise bandwidth control. This allows a stable and continuous measurement with variable water levels and flow conditions.

Measurement campaigns and the visualization of the data are carried out via the  PC software RiverSurveyor® Live.

RiverSurveyor® M9:
The solution for flow measurements in deep waters, even in flood situations. Highest resolution combined with maximum measuring range. The nine-beam system with two sets of four profiling beams each and one vertical beam for accurate depth measurement. The M9 has a measuring range (speed) of up to 30 meters and a depth measuring range of up to 80 meters.Portables 9-beam profile / flow measuring system according to the Acoustics Doppler principle up to 40 m water depth..

Application areas:
  • mobile flow measurement - mobile measurement of flow velocity and flow for
  • Natural streams
  • Artificial channels
  • waterways
  • Measurements in case of flood
