The Description About Alia AVF7000
Steam Flow Meter 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 flow meters are versatile flowmeter widely used for Gases, Steam & Liquid applications. There are no moving parts and comes with either Flange or wafer connection.
The standard configuration has a local indication for flow rate and total flow as well as a 4-20mA output functions. The microprocessor design can filter out erroneous signals as well as interference caused by pipe vibration.
Features
- Simplified setup and self-diagnostic functions
- Auto. Temperature & Pressure compensation
- 4-20 mA and pulse outputs, user-selectable
- a very wide selection of sizes
- Wide temperature range which can up to 420 Deg. C
- Non-volatile memory for setup and calibration.
