Contactless flow measurement for wastewater treatment plant - Water and Wastewater - Water Treatment

Application: Concrete channel, width 1.2 m. Part filled. Measurement point upstream of screen and grit trap. High sedimentation loads.

  • Intake measurement as control measure to avoid WWTP flood
  • Contactless measurement system due to partially high pollution loads
  • Easy installation
  • No Ex required (open, aerated channel)

  • No sensors can be installed on the channel botton or in floats due to high pollution loads or foam on the surface.
  • The surfaec radar measurement system Type NivuFlow 550 has been used since the measurement is for control purposes only without the need for certification.
  • The system measures the velocity of the surface waves and calculates the current flow rate from this velocity, the measured level and the defined rectangular channel shape.

  • Contactless
  • Insensitive to soiling
  • Easy to install
