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 Torrent Board Micro and SonTek-RTK, you will be ready to quickly collect the highest quality water velocity and flow measurement possible regardless of your environmental water monitoring takes you.

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.
