AVF7000 : Vortex Flowmeter
AVF7000 Series
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 oC
- Non-volatile memory for setup and calibration
