AVF 7000 Series

ALIAVTX AVF7000 is a Vortex Flowmeter 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 have local indication for flowrate and total flow as well as a 4-20mA output functions. The microprocessor design can filter out erroneous signals as well as interfence caused by pipe vibration.
