Alia Vortex Flow Meter | Gas Flow Meter
Flow Meter Gas
ALIAVTX AVF7000 is a Vortex Flowmeter
based on the Von Karman 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.
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
