Teledyne RD Instruments RiverPro ADCP

Benefits

Efficient, accurate, high resolution: Using the moving boat method, the RiverPro can be continuously guided 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 very high accuracy and resolution of the flow profile.

Wide range of applications: With a measuring range from 0.2 m to 25 m, RiverPro covers virtually the entire range of applications. Higher concentrations of suspended matter normally do not pose a problem for the 1200 kHz ADCP sensor.

User-friendly: The RiverPro automatically detects the optimal measurement mode, so the user can immediately start measuring after entering the bank distance. 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.) is provided to the user in a clear form.

Optimized equipment rack: The trimaran of RiverPro has a particularly favorable flow design, which is beneficial both at very low and high flow rates. The hull of the centerpiece 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 the convenient transportation of RiverPro.

Modular: Other useful extensions for RiverPro 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.

1) Distance from the center of the first measuring cell to the sensor surface
2) The actual range depends on temperature distribution and concentration of suspended matter
3) for average depth data
4) is valid for even temperature and conductivity distribution
5) applies to tilt values <+/-70° and angle of incidence <70°
