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. Like the RQ-30, this method is based on innovative radar technology including all the advantages of a contactless measuring device.

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, especially used in flooding and natural hazard management.

  • Portable mobile measuring system
  • Simple mounting on cable cranes, bridge railings or tripods
  • Suitable for flood conditions and high flow velocities
  • Contactless radar measuring technology
  • No exposure to floating debris
  • 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 flow conditions)
