Mobile measuring system for non-contact discharge measurement
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. It's a very helpful measuring device especially for the use in flood conditions.
- 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)
The Radar Profiler is ideally suited for selective measurement and therefore for project evaluation or control measurements. In contrast to most other measuring devices it provides reliable values even in flood situations - an extremely interesting situation from a hydrological point of view - and is, therefore, particularly used in flooding and natural hazard management.
With the aid of an adjustable traveller for handrails the Radar Profiler can be easily moved along a bridge railing to the desired measuring points. Alternatively it can be fixed to a cable crane or tripod. The measurement is then carried out in sections across the whole width of the water. Thanks to the integrated Bluetooth transmitter the data are transferred directly to a laptop during the measurement and can so be viewed in real time.
