VFM60 Vortex Flow Meter (Enhanced Model)

VFM60 is a powerful flow meter utilizing “Karman vortex” theory, which can meet the requirement of measuring the flow rate of various fluids such as gas, steam and liquid. The product uses the VFM60 transmitter 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 unique dual-sensor design and special signal processing method has also ensured a better anti-vibration by eliminating the vibration signals to provide more reliable performance and lower measurement limit. The VFM60 platform is also an open platform, which means we can keep on upgrading its function according to customer’s unique requirement, and make the product a highly custom-orientation product.

    VFM60 vortex flow meter is the latest product that combines COMATE’s most advanced technologies. It has 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. The meter also provides with a super low measurement limit down to 2m/s for gas and steam and a 1:35 turn down ratio.  VFM60 vortex flowmeter is the most powerful vortex flow measurement technology in the market.
     
     

    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.
