Aanderaa Doppler Current Profiler Sensor (DCPS)

The Doppler Current Profiler Sensor (DCPS) is a medium-range, 600kHz current profiler smart sensor. It features innovative development of the acoustic profiling ability to collect high-quality current information also on moving and tilting platforms. Available as 300m depth rated (5400/5400R), 4500m (5402/5402R), 6000m (5403/5403R).

The DCPS 5400/5402/5403 can be connected to a SeaGuardII or SmartGuard using the CANbus based AiCaP protocol. It can also be connected to a PC or third party systems through the RS-232 interface using the AADI Real-Time Collector or SmartSensor Terminal protocol. This makes the DCPS the ideal cost-effective solution for obtaining current profiles in systems already containing a Datalogger. The 5400R/5402R/5403R has the RS-422 interface for use on longer cables.

Exceptional compensation in moving applications

Measurements are compensated for instrument movement :

  • Each ping is compensated for the corresponding tilt and heading, taking into account mooring or buoy motions
  • The Doppler current profiler sensor calculates the correct vertical distance to a specific cell for each beam.

Optimal flexibility

  • Easy to use
  • Configuration flexibility
  • Upward or downward-looking
  • User-selectable broadband or narrowband modes matching different applications
  • Address different applications scenarios using a single instrument; up to three profiling configurations simultaneously; each profiling column can be set up with individual cell size and cell overlap
  • Surface current feature; measure in the top centimeters layer*
  • Surface referred columns; the column keeps a fixed distance to the surface to follow water level changes*
  • Direct readout of engineering data
  • Configurable output format

Increased deployment time

  • Low power consumption
  • Reduced power consumption with broadband technology

Smart Data quality control

  • Increased quality control
  • Automatic flagging of bad data; status report for each cell
  • User-selectable advanced auto beam algorithm; automatic selection of the best 3-beam combination to remove faulty cells in case of an object passing in front of one beam

Sensor communication protocols

The AADI Real-time collector PC software can be used together with all DCPS versions. It simplifies the sensor configuration process and saves sensor data to files on a PC. The AADI Real-Time communication protocol is an XML-based protocol that also includes numerous metadata for all the data parameters from the sensor. The Smart Sensor Terminal protocol is a simpler protocol that gives smaller message sizes since it includes a limited amount of metadata in the output. The size of the output message can be reduced in both protocols by only enabling the necessary data parameters. Both protocols use ASCII output which makes it directly readable without any conversion (no binary data).
