Definition of tasks
- Detection of flow rates in a large main collector of a combined sewage channel network ranging from low nightly discharge to flood events.
- Due to sedimentation, stones and debris, sensors cannot be installed on the channel bottom.
- During rainfall events, the collector may be completely flooded and may build up pressure.
Solution
- The newly developed NivuFlow 7550 hybrid system with combined flow velocity measurement using contactless surface radar and a laterally installed medium-contacting cross correlation sensor was used.
- The partially filled level is detected using ultrasound from top down, high levels and flood are detected by the pressure cell integrated in the cross correlation sensor.
