Application

• Rectangular channel, 6 m width
• Partially filled
• Simultaneous overflow from several chambers into one common channel
• Short calming section upstream of measuring point

Definition of tasks

• Detection of overflow volumes to recipient
• Readings shall be transmitted to control system via analog and digital outputs
• High accuracy at varying overflow volumes per chamber

Solution

• Providing highest measuring dynamics and accuracy, a cross-correlation-based system Type NivuFlow 750 M3 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. Protective metal sheets prevent the sensors from being damaged.
