Flow vortex measuring

Vortex Flow Measurement
Mode of operation of a vortex meter
Vortex frequency

Sensor Concept
Capacity sensor
Primary vibration compensation (balanced system)
No weld seams in the process
11,600 psi (800 bar)
Insensitive to dirt
Insensitive to temperature shocks (>150 K/s)
Insensitive to pressure shocks
Negative electrode
In the vortex meter the vortices are generated by a flow body which is installed in the flow direction upstream of the sensor.
Sensor Concept - Proline Prowirl
Functional Principle

Vortex Flow Measurement
Vortex Flow Measurement
Continuous processes, no pulsations, viscosities < 10 mPas
Flow profile: inflow and outflow sections required
  • Linear frequency output
  • Can be used for steam, gas and liquids
  • Low pressure drop
  • Large nominal width range
  • Low installation costs
  • Wide measuring range
  • No moving parts
