Efficient, accurate, high resolution:
Using the moving boat method, RiverRay can continuously be driven over the measurement cross-section on a rope or a rubber dinghy, etc.. Hereby, the ADCP sensor measures the average flow velocity in different depth cells and water depths. Unlike the point measurement method or verticals procedure, discharge measurement is performed not only in a fraction of the time but also with a very high accuracy and resolution of the flow profile.

The high-performance 600 kHz broadband ADCP sensor is the first choice, especially during floods and high-sediment transport. Where all conventional measuring methods or ADCPs reach their limits, RiverRay measures precisely and reliably from 0.4 -60 m water depth.

RiverPro automatically detects the optimal measurement mode, so the user can immediately start measuring after entering the distance from the bank/shore. The division of the cell sizes is also carried out fully automatically and it varies depending on the water depth. With the help of the supplied Software WinRiver II all relevant information (flow profile, current flow, etc.) are provided to the user in a clear form.

Optimised equipment rack:
The RiverPro trimaran has a particularly favourable flow design, which is beneficial both at very low and high flow rates. The hull of the center piece contains plenty of storage space to protect the battery, the ADCP sensor and the further components (e.g. radio modems, GPS) against moisture and flotsam. The two cantilevers of the trimaran can be folded in a few simple steps, thus facilitating convenient transportation of RiverRay.

Other useful extensions for RiverRay are immediately available to the user or, if necessary, at a later date: Section-by-Section, Q-Boat (equipment rack with a motor drive and remote control), external GPS.
