| VFM45 Vortex Flow Meter(Economical Model) |
VFM45 digital vortex flow meter 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 VFM45 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 special signal processing method has also ensured a better anti-vibration by eliminating the vibration signals. The VFM45 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. |
