Vortex Flowmeter

Model AVF7000 Series

GENERAL
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 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.

FEATURES
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 °C
Non-volatile memory for setup and calibration
