24VDC & Battery power supply for option
VFM55 vortex flow transmitter has lower power consumption, with build-in ER26500 lithum battery, it can ensure long-term battery life. Avoding flow data missed due to power ourages. It also has a 24VDC power supply port.
Anti-vibratin performance
VFM55 vortex flow transmitter have a patent dual-sensor design and is using our latest VPA60 transmitter, which enable it to detect and eliminate vibration signal, and provide with best anti-vibration performance.
