The Vortex Flow Meter is used for measuring the flow velocity of gases or liquids in pipelines flowing full. The measuring principle is based on the development of a Karman Vortex shedding street in the wake of a body built into the pipeline. The periodic shedding of eddies occurs first from one side and then from the other side of a bluff body (Vortex-shedding body) installed perpendicular to the pipe axis. Vortex shedding generates a so-called “Karman Vortex street” with alternating pressure conditions whose frequency is proportional to the flow velocity.

Applications

  • Boiler industry (Steam measurement)
  • Compressed air industry
  • Textile industry
  • Paper Industry
  • Heating industry
  • Metallurgical industry
  • Plastics processing
