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.

FEATURES

  •  Simplified setup and self-diagnostic functions  

  •  Auto. Temperature & Pressure compensation   

  •  4-20 mA and pulse outputs, user selectable  

  •  a very wide selection of sizes  

  •  Wide temperature range which can up to 420 Deg. C  

  •  Non-volatile memory for setup and calibration
