SonTek-RS5

Want to know what the discharge data collection buzz is about - you’re at the right place! The SonTek-RS5 is the world’s most compact and robust ADCP for collecting river, stream, and canal discharge data. The RS5 is small yet powerful. When paired with the custom-designed HydroBoard II Micro and SonTek-RTK, you will be ready to quickly collect the highest quality water velocity and flow measurement possible regardless of where your environmental water monitoring takes you.

• Overview

  Packed with All the Features, You Expect
  The SonTek-RS5 comes loaded with advanced data collection capabilities, high-precision data quality, and flexible deployment options customers have grown used to with SonTek ADCPs over the years.

  

  • Vertical Acoustic Beam: Superior channel definition for the most accurate cross-sectional area for discharge applications. Measures the depth directly under the system and extends maximum discharge depth if bottom-tracking is out of range. 360º compass and two-axis tilt sensor
  • SmartPulse+®: An intelligent algorithm utilizing Pulse-coherent and Broadband acoustic profiling that automatically adjusts based on conditions—reliable bottom tracking and velocity profiling in water depths shallower than ever. Visualize velocity data like never before with cell sizes down to 2.5 cm.
  • 360º compass and two-axis tilt sensor: Reports vessel heading and magnetic error and compensates for motion due to surface conditions. The tilt sensor uses pitch and roll to correct depth and velocities.
  • RTK GPS (Option): Ultra-precise positioning as an alternative to bottom tracking in moving beds or other difficult situations. Geolocate each sample (or ensemble) during measurement. Corrections are sent from the SonTek RTK base station or a local NTRIP.

  • DGNSS (Option): Integrated DGNSS smart antenna for position as a backup or alternative to bottom tracking in moving bed or other challenging conditions.

  RSQ: Visualize and Process Data Like Never Before!

   RSQ is a modern and user-friendly software interface. One measurement file includes all the data and metadata you need for each measurement. Export data to formats for Excel, Matlab, Google Earth, Kisters, and AGILA. Do more with less time utilizing improved site templates. Experiment, learn, or teach in the office or conference room as though you were in the field with the option to playback recorded files simulating live data collection. Flexibility is key with RS5.

  WITH RSQ, YOU CAN:

  • Collect both moving boat or stationary measurements
  • Connect to Network RTK (NTRIP) within the network range
  • Use GNSS to calculate the distance between stations for stationary measurements
  • Run and apply Extrap (USGS) to both moving boat and stationary measurements
  • Sub-section moving boat transects and recalculate discharge
  • Choose beam switching (3-beam solution) when one beam shows interference 
  • Process *.riv/*.rivr files from SonTek’s M9 or S5
  • Save data on a PC, external drive, or network
  • Custom file naming option
  • Select between GNSS or built-in magnetic compass for heading
