Application

• Drainage line DN 300 of leisure park
• Part filled
• Concrete drainage line in ailing condition
• High discharge dynamics and turbulent discharge due to upstream feed pump
• Ex Zone 1

Definition of tasks

• Determination of channel capacity and costs allocation for the planned expansion of the leisure park
• Accurate detection of flow rates to determine the dimensions of a newly planned wastewater line
• The poor hydraulic ambient conditions and the high discharge dynamics should not affect the demanded measurement accuracy of the system used.

Solution

• To improve the poor hydraulic discharge conditions a mobile Type NPP measuring pipe was inserted into the approaching pipe by using a bubble.
• Thanks to the aid of a 90° elbow the pipe was full filled resulting in otimum measurement conditions.
• The flow velocity detection was carried out based on the ultrasonic cross correlation principle.
• Power supply and data storage were implemen-ted through a battery-powered PCM Pro transmitter.
