The Vortex Meter type VTX2 operates on the principle of the Karman vortex street. The replacement frequency of vortices formed after the bluff body is scanned by patented sensor and microprocessor-controlled electronics and converted into a flow signal.


  • Line Size Ranges: 15mm to 150mm
  • Best suited for flow measurements where the introduction of moving parts presents problems
  • Extremely robust and resilient
  • Excellent metrological characteristics
  • Excellent compensation of vibrations
  • Insensitive to pulsation, hydraulic shock and thermal shock


Vortex meters generally have a wide range of application. They are used in various industries:

  • Flow measurement of gas and steam
  • Flow measurement of conductive and nonconductive fluids
  • Use of measuring points which is a particularly robust measurement
  • Volume measurement for accounting (eg: compressed air systems, heat carriers, steam, chemical products)
  • Process control
  • Applications with high flow rate
