Measuring an asymmetric flow profile - Water and Wastewater

Application: Rectangular channel, 2.5 m width. Part filled. Rectangular channel made of concrete. Fluctuating asymmetric flow conditions.

Definition Of Task

  • Detection of flow volume to wastewater treatment plant
  • The measurement shall be as accurate as possible despite constantly fluctuating flow conditions and varying flow profile


  • Providing highest measuring dynamics and accuracy, a cross-correlation-based system Type OCM Pro has been used. By using 3 flow velocity sensors simultaneously it is possible to detect and to consider existing asymmetric flow conditions.
  • The sensors have been installed on the channel bottom.


  • Low installation costs
  • Complies with requested accuracies by utilising 3 velocity sensors
  • Maintenance-free
