AVF7000 Series

AVF7000 Series

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 has local indication for flowrate and total flow as well as 4-20mA with HART signal and pulse output functions. The microprocessor design can filter out erroneous signals as well as interfence caused by pipe vibration.
