AVF7000 Series Vortex flow meter

AVF7000

Series Vortex flow meter

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.

FEATURES

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