With the mobile measuring device RP-30 (Radar Profiler) a surface velocity profile from rivers and channels is created and together with the data of the river cross-section and water level the discharge is determined. - A very helpful measuring device especially for the use in flood conditions.

Features and advantages
- Portable mobile measuring system
- Simple mounting on cable cranes, bridge railings or tripods
- Suitable for flood conditions and high flow velocities
- Non-contact radar measuring technology
- No threat from debris or driftwood
- Calculation of discharge with known water level and cross section profile
- Easy operator controls and handling
- Remote data transmission via Bluetooth
- Measuring range from +/- 0.10 to +/- 15 m/s (depending on the flow conditions)

Fields of application
The RP-30 is used in rivers, streams and open channels and calculates the exact discharge of the body of water through several sectional velocity measurements. As is the case with the RQ-30, this method of measurement is also based on innovative radar technology including all the advantages of a non-contact measuring device.

The Radar Profiler is ideally suited for situationally and non-permanent monitoring tasks, for project evaluations or control measurements. In contrary to most other measuring devices it provides reliable values even in flood situations, which is an extremely interesting situation from a hydrological point of view and where most other sensors fail to be used. Therefore the RP-30 is particularly useful in flooding and natural hazard management.
