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
