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
Vortex Steam Mass Flowmeter
Vortex flowmeter 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 a flow computer for mass flow
VFM45 vortex steam flow meter transmitter has been installed over 5000 pcs, provide the most reliable and durable measurement solution
