The RiverSurveyor 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 M9 has revolutionized the way discharge is measured in rivers and canals.
Multiple acoustic frequencies with SmartPulseHD make for the most robust and continuous shallow-to-deep measurements ever and an array of four deterministic microcontrollers expertly apportion the proper acoustics, pulse scheme, and cell size allow users to focus on the measurement – not the 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 M9 handles it all on the fly.
The RiverSurvery M9 will exceed your expectations during and after the measurement with the RiverSurveyor Live! software suite for both PC and mobile platforms. All programs take full advantage of SmartPulseHD and the intelligent software ensures no loss of data during telemetry dropouts, with multi-language support available. Easily switch between computer or mobile devices during mid-measurement. Several quality indicators and statistics with selectable graphics provide instant feedback on data collection.
