Non-contact flow measurement for surface running waters, like rivers, streams, channels, canals or open canels. Radar sensors detect gapless all flood data at high water. The system is also suitable to use as evidence of outward flow in power plant operation.

  • Free of maintenance
  • No structural measures in water bodies required
  • Simple integration into existing systems
  • No system risks at high water
  • Low energy consumption, solar operation possible
  • Detection of flow direction
  • Measuring range from 0,30 to 15 m / s
  • Measurement in ebb tide / flood affected waters
  • Analogue output (RG-30a)
