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

Definition of tasks

• 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

Solution

• 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.
