VFM45 Steam Vortex Meters | Vortex Steam Mass Flowmeter Device

VFM45 provides with excellent signal processing capability and enhances the vortex street metering technology to a new level, which means it has a lower measuring limit, better stability, and accuracy. The special signal processing method has also ensured a better anti-vibration by eliminating the vibration signals.

Application:

  • Saturated/superheated steam measurement and custody transfer measurement
  • Steam boiler system measurements
  • Measurement of other process gases
  • Gas drainage in coal mines
  • Measurement of liquids, especially of non-conductive liquids
