Profiling Current Meter and Wave

Profiling Current Meter and Wave - The optimal solution to measure current, speed, direction, and water quality in one instrument

Model: SeaGuardII DCP Wave

Manufacturer: AANDERAA

Made in Nauy

Profiling Current Meter and Wave – The optimal solution to measure current, speed, direction, and water quality in one instrument.

Simple solution to measure waves, currents and water quality in one instrument

  • Independent measurement of waves and currents.
  • Field validated data-comparison with MOTUS buoy, Datawell Waverider and pressure based non directional wave sensor
  • Measures wave from centimeters to 20m
  • 2Hz or 4Hz wave sampling
  • Processing of up to three columns in parallel, provides flexible setup with both surface referred and bottom referred cells.

Adaptive pulse technology automatically optimizes wave measurement accuracy. The transmission pulse is automatically adapted to the current sea conditions to provide best measurement achievable; a low noise broadband mode is used for smaller waves, an extended range broadband mode used for medium range waves and a narrowband mode is applied for higher waves.

Category:

The SeaGuardII DCP Wave is a 600kHz Doppler Current Profiler able to measure directional wave parameters and currents from a bottom mounted installation.

The Acoustic Wave software 5759 used by the DCPS implements unique features to improve the wave measurement accuracy by optimizing the signal to noise ratio.
Maximum deployment depth is 40m in normal scatter conditions. The Profiling Current Meter and Waveis available as a self-recording instrument. It can be easily integrated into a real-time system offering reliable two-way communication.

Redundant wave measurement for QA/QC can be implemented by adding the wave and tide sensor 5218.

Applications

  • Navigation safety
  • Prediction and modelling
  • Energy assessment
  • Infrastructure design
  • Coastal processes, erosion
  • Oil & Gas

The optimal solution to measure directional waves, currents and water quality in one instrument

  • Real-time or self-recording with on-board processing of current and wave parameters from a bottom installation
  • Independent measurement of waves and currents with flexible set-up
  • A wide range of parameters available using Aanderaa plug and play smart sensors
  • Easy integration of third-party sensors
  • Adaptive pulse technology optimizing wave measurement accuracy

Innovative technology to ensure accurate low noise wave measurement

  • Covers the complete wave range (0.2m to 20m) without sacrificing accuracy
  • Automatically switches between two broadbands and one narrowband mode depending on wave height
  • Samples waves at 2Hz or 4Hz with a configurable integration interval from 5 to 30 minutes
  • Field proven and validated data

Comparison and validation using three other methods for wave measurement, including surface buoys

  • Possibility to integrate a wave pressure based sensor for redundant measurement and quality assurance
  • Most efficient current and wave profiler on the market offering ease of use and proven data quality
  • Maximum deployment depth of 40m
