The RiverSurveyor S5/M9 is a river discharge measurement system without the traditional limitations. Small, portable and easy to use, the patented and award-winning RiverSurveyor measures in extreme flood or drought situations within a single instrument, and without changing user settings. The results speak for themselves – the RiverSurveyor S5/M9 has revolutionized the way discharge is measured in rivers and canals.
It’s a SonTek exclusive – multiple acoustic frequencies with SmartPulseHD® make for the most robust and continuous shallow-to-deep measurements ever. An array of four deterministic microcontrollers expertly apportion the proper acoustics, pulse scheme, and cell size so you can focus on the measurement – not the instrument setup. The system even has a vertical beam for accurate channel definition and it’s all designed to work intuitively. Slow to fast, shallow to deep, the RiverSurveyor S5/M9 handles it all on the fly.
Taken to Incredible Extremes.

“Meeting of the Waters” Amazon River near Manaus, Brazil
Multi-band (Multiple acoustic frequencies)1,2
Balances the highest resolution with the greatest range of depths.
Vertical acoustic beam1
Superior channel definition for both bathymetric and discharge applications. Extends maximum discharge depth when bottom-tracking is out of range.
An intelligent algorithm that looks at water depth, velocity and turbulence, and then acoustically adapts to those conditions using pulse-coherent, broadband, and incoherent techniques. High-def cell sizes down to 2 cm.
Microprocessor computed discharge and secure data1
All discharge computations are simultaneously done both within the S5 or M9, and on the host computer. No lost data if communications drop out.
Standard 360º compass and two-axis tilt sensor
Compensates for vessel motion due to surface conditions.
Reverberation control with ping rates to 70Hz
High ping rates ensure extremely robust data collection.
Acoustically track vessel speed over ground independent of DGPS. Also supplies redundant depth measurement.
RTK GPS (optional)
Ultra precise positioning as an alternative to bottom tracking in moving bed or other difficult situations.
