RiverSurveyor® S5 and M9
The RiverSurveyor®, S5/M9 systems give a new perspective to the notion of measuring open channel hydraulics. Using SonTek’s exclusive SmartPulseHD™, multiple acoustic frequencies are fused with precise bandwidth control for the most robust and continuous shallow-to-deep discharge measurements ever. A deterministic microcontroller expertly apportions the proper acoustics, pulse scheme, and cell size to get the highest definition possible so you can focus on the measurement, not the instrument setup. The system even has a vertical beam for precise channel definition and it's all designed to work intuitively.RiverSurveyor Brochure (1MB) [PDF]

| Features | Benefits |
| Multi-Band* (Multiple acoustic frequencies) | Balances the highest resolution with the greatest range of depths |
| Vertical acoustic beam* | Superior channel definition, extends the maximum measurable discharge depth |
| SmartPulseHD™* | 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 data* | All discharge computations are done within the S5 or M9 unit internally (not in the computer!) – No lost data from communications drop outs |
| 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. |
| Bottom-tracking | High precision vessel tracking and depth measurement without GPS requirement. |
| RTK GPS (optional) | Ultra precise earth-referenced positioning as an alternative to bottom tracking in moving bed or other difficult situations. |

Doppler technology has several inherent advantages that make it the preferred method for current measurement. Combining this with SonTek’s proven ability to develop instruments that are both powerful and easy-to-use, the RiverSurveyor S5 or M9 is the ideal choice for moving boat discharge measurement.

Use RiverSurveyor LIVE software to enjoy new S5/M9 features unlike those you have ever seen before. Experience sharp, vivid and high defiition velocity data with SonTek's new SmartPulseHD™ now available for RiverSurveyor S5/M9 systems. RiverSurveyor LIVE! Expanded Description
SmartPulseHD is an intelligent algorithm that looks at water depth, velocity and turbulence, then adapts the acoustic pulse scheme to those conditions. It's uses a variety of cutting edge technology - multi-band acoustics, pulse-coherent, broadband, and incoherent techniques to provide the highest resolution possible. And see the clearest velocity picture possible with cell sizes down to 2 cm.
This software includes language support for English, Chinese, Japanese, Spanish, Catalan, French, German, Italian, Korean, Portuguese, Turkish, and Hungarian.
- Load, view, and analyze multiple data sets simultaneously.
- Collect data and disconnect/ reconnect again. Easily swap between phone and laptop mid-measurement.
- View multiple data results (bottom-track, GPS-GGA, and GPS-VTG) simultaneously.
- Quality status/data, statistics, and color coded graphical display for clear feedback in the field.
- Customizable interface, graphs, and tabular data.
- Reports, ASCII & MATLAB® export.
