Gas Vortex Flow Meter

Gas Vortex Flow Meter ALIAVTX AVF7000 is a Vortex Flowmeter based on the Von Karman 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.

Flow Meter Gas

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. The standard configuration has a local indication for flow rate and total flow as well as a 4-20mA output functions. The microprocessor design can filter out erroneous signals as well as interference caused by pipe vibration.
