Flow measurement on flood polder for flowing waters - Water and Wastewater

Application: Concrete duct 6 x 3.5 m (w x h). Partially filled. 3 parallel ducts. Very high flow dynamics featuring flow rates up to 82 000 l/s.

  • Detection of flood polder flow volumes of a large European river
  • Control of storage volume utilisation (12 000 000 m³ on 5.8 km² flooding area) to reduce flood damage
  • Highly dynamic and maintenance-free measurement insensitive to sedimentation

  • Three flow measurement systems Type NivuFlow 750 M3 with each using 3 flow velocity sensors have been used.
  • The sensors have been arranged according to a calibrated hydraulic model to achieve maximum possible accuracy.
  • Sensors have been installed on profiles in order to prevent them from soiling.

  • Cost-efficient sensor installation in existing construction
  • Quick and easy commissioning
  • High accuracy and reliability
