VFM-45

VFM45 Digital Vortex Mass Flowmeters|Steam Mass Flow Measurement Technology

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

PRODUCT DESCRIPTION

Application:
  • Saturated/superheated steam measurement and custody transfer measurement
  • Steam boiler system measurrement
  • Measurement of other process gases
  • Gas drainage in coal mines
  • Measurement of liquids, especially of non-conductive liquids
Feature
  • Vortex flow measures down to 5m/s for gas/steam.
  • No moving parts, very small pressure loss
  • Isolated design for electrical parts to eliminate interference
  • Wide power source adaptability to fit in different applications
  • 2 lines LCD display
  • Standard output is pulse and 4~20mA , Hart@4~20mA and RS485 is available
  • Metric/British Unit selectable
  • Density compensation function available, do not need flow computer for mass flow
  • VFM45 vortex flowmeter transmitter have been installed over 5000 pcs, provide the most reliable and durable measurement solution
High sensitivity, measurement limit odwn to 5m/s for steam

VFM45 has high sensitivity senor and powerful signal processing technology, which ensures it can provide with 1%RD accuracy even at 5m/s flow.

Density Compensation Programmed

Can Work wit separate RTD and pressure transmitter to calculate mass flow or standard flow, do not require a mass flow meter
