AVF7000 Series

The LZN7000 Series 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 LZN7000 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 4-20 mA with HART signal and pulse output functions. The microprocessor design can filter out erroneous  signals as well as interfence caused by pipe vibration.
