AMF500 Series
The AMF500 Series is a wafer-type electromagnetic flowmeter ideal for conductive liquids. It comes in sizes from 50-200 mm.
AMF500 is widely used for tap water, waste water, food & beverage, pulp & paper and many other industrial fluids.
AMF500 Series electromagnetic flowmeter can be used in compact or remote model with AMC Series converter of electromagnetic
flowmeter.
AVF7000 Series
The AVF7000 Series is a Vortex Flowmeter based on Von Karman's theory of vortices generated by a bluff body in the pipe. The number of vortices is linearly proportional to the volumetric flow in the pipe. The AVF7000 is a 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 4-20 mA with HART signal and pulse output functions. The microprocessor design can filter out erroneous signals as well as interference caused by pipe vibration.
