Flow Survey at Waste Water Treatment Works

Flow Survey

Customer required flow survey to check feasibility of using ultrasonic clamp-on flow meter technology for measuring consistency of flow within pipe repeatedly over a period of time.

The feasibility tests were carried outusing a Flexim F601 ultrasonic clamp-on flow meter and K Shearwave transducers.


  • Pipe Size: 610mm
  • Wall Thickness: 9.5mm
  • Medium: Waste Water


During the test we observed negative flow. An investigation found an issue with a non-return valve.

The cost of the unit paid for itself within ten minutes.

This led to the customer purchasing three units of Flexim Fluxus WD400 which are permanently fixed non-invasive ultrasonic flow meters.
