Aliavtx avf7000 is a vortex flowmeters based on von karman theory of vortices generated by a bluff body in the pipe. The number of vortices are linearly proportional to the volumetric flow in the pipe.
The avf7000 is versatile flowmeter widely used for gases, steam & liquid applications. There are no moving parts and comes with either
Flange or wafer connection. Standard configuration comes with local indication for flowrate and total flow as well as a 4-20ma output function output. The electronics are designed to filter out erroneous signals as well as noise due pipe vibration.
