Critical Flow Measurement in Big Pipe

Industry - Power Plants


  • Pipe DN 2400 made of wrapped GRP
  • Partially filled
  • Cooling water (seawater) with max. flow rate of 60.00³/h from power plant


Definition of tasks

  • Accurate flow detection at flow velocities up to 6 m/s
  • No holes are allowed to be drilled into the plastic pipe


  • A permanent flow transmitter Type NivuFlow 750 with wall mount enclosure has been used. As accompanying sensor the high-performamce flow velocity sensor Type CS2 utilising the ultrasonic cross-correlation method has been selected.
  • The sensor has been fastened on the pipe bottom using a mounting sheet and a special synthetic resin adhesive.
  • An external ultrasonic level measurement using a NivuNaster L2 with a p10 sensor has been installed additionally as redundant level system
