Vortex Flowmeter

ALIAVTX AVF7000 Series

Vortex Flowmeter


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.

  • Simplified setup and self-diagnostic functions
  • Auto. Temperature & Pressure compensation 
  • 4-20mA with HART signal and pulse outputs, user selectable
  • A very wide selection of sizes
  • Wide temperature range up to 420 oC
  • Non-volatile memory for setup and calibration
