RiverSurveyor S5 YSI RS-S5

The RiverSurveyor S5 is a river discharge measurement system that has no limitations compared to a traditional river surveyor system. It has a transducer configuration of five, a bottom-track discharge measurement of .3 to 5m, and a RTK GPS measurement of .3 to 15m. The RiverSurveyor S5 is an award-winning for measures in extreme flood or drought situations within a single instrument and without changing user settings. It has revolutionised the way discharge is measured in rivers and canals and the SonTek exclusive SmartPulseHD allows for the most robust and continuous shallow-to-deep measurements.

Key Features and Benefits:

• Multi-Band - Multiple acoustic frequencies


• Vertical acoustic beam


• SmartPulseHD®


• Internally computed discharge and secure data


• Standard 360º compass and two-axis tilt sensor


• Reverberation control with ping rates to 70Hz


• Bottom-tracking


• RTK GPS (optional)


• Balances the highest resolution with the greatest range of depths


• Superior channel definition, extends the maximum measurable discharge depth


• 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


• All discharge computations are done within the S5


• Compensates for vessel motion due to surface conditions.


• High ping rates ensure extremely robust data collection.


• High precision vessel tracking and depth measurement without GPS requirement.


• Ultra-precise earth-referenced positioning as an alternative to bottom tracking in moving bed or other difficult situations
