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.

Advantages

  • Easy, quick and safe installation through lightweight plastic pipe.
  • Exactly defined cross section
  • Homogenised flow conditions at the measurement point and therefore highest system accuracy.
