NIVUS Pipe Profiler II

Part No. NPP0

Pipe measuring section as extension to the mobile flow measurement system Nivu Flow Mobile 750.

The measurement system ensures highly accurate determination of flow rates even under difficult conditions such as low flow volumes or poor hydraulic flow conditions.

  • Verification of channel utilisation
  • Calibration basis for hydraulic calculation models
  • Determination of required renovation extents
  • Determination of required reservoir volumes (retention basin)
  • Introduction of a channel management system
  • Localisation of extraneous water volumes
  • Influent control
  • Throttle discharge control
  • Determination of basic data for new billing networks
