WTW Flow and profilometer HydroSurveyorTM M9
.
The HydroSurveyorTM is an ADCP for flow rate and flow rate detection including sonic velocity correction.
  • user-friendly software with automatic data grids and data interpolation
  • Simultaneous measurement with five echosounders guarantees a high measured value density
  • Automatic sound velocity correction with CastAway CTD

The HydroSurveyorTM consists of the Acoustic Doppler Profiler (ADP) - a transducer with eight transducers and a sonar. In addition, there is a 360 ° compass, a 2-axis tilt sensor and the integrated electronics for data processing. The system can be extended by various power and communication modules as well as DGPS / RTK options.

Depth and flow rate measurements can be stored and evaluated using the HydroSurveyorTM software. In addition to the automatic correction of the speed of sound bathymetric maps of the investigated waters can be created.
