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.

FEATURE

• 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 ℃
• Non-volatile memory for setup and calibration
