Conceived to advance measurement practices, the RiverSurveyor S5 and M9 systems give a whole new perspective to the notion of measuring open channel hydraulics. Multiple acoustic frequencies fused with precise bandwidth control make for the most robust and continuous shallow-to-deep measurements ever. A deterministic microcontroller expertly apportions 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 precise channel definition – and it’s all designed to work intuitively.
