High sensitivity sensor, advanced signal processing technology and best anti - vibration features ensures the meter to provide 1%RD accuracy even at a super low velocity of 2 m/s for gas and steam
Dual-sensor design and patent digital signal processing technology ensures the meter can distinguish the vibration signal from the flow signal and eliminate it, to provide with best anti vibration preformance
Traditional vortex technologies are easily effected by vibration. In order to provide stable result, they can only cut off some useful signal mixed with vibration signal and flow signal
VFM60 vortex meter can distinguish the vibration signal from the flow signal, and eliminate the interference. So it can provide stable reading under vibration even the flow is down to 2m/s.
