Introducing ASF7100 Alia Vietnam
The ASF7100 series vortex flow meter is a gas flow meter that combines turbine and vortex flow measurement technology to provide a reliable, highly accurate, robust and maintenance-free flow meter .
The turbine-shaped flow inlet causes the flow to rotate causing the vortex core to form and the subsequent secondary rotation to create thread-like spirals.
These obtained secondary pressure frequencies are linear and proportional and are measured using a dual piezoelectric sensor.
The resulting measurements are processed & compensated for pressure & temperature, then converted to a flow measurement display.
ASF7100 series vortex flow meter can be widely used in petroleum, chemical, power, metallurgy, coal and other industries.
Features of ASF7100 Alia Vietnam
- 2 Built-in sensors reduce external vibration/frequency interference
- There are no integrated moving parts to ensure a stable, reliable and long life
- Integrated temperature and pressure measurement ensures practical compensation
- Multiple O/P signals: 4-20 mA, Pulse, RS485, Alarm
- Adjustable display/results (90 o , 180 o , 270 o , 360 o ) Simple adjustment
- Powered by battery or external DC power
- Reduced pressure loss due to internal piping configuration
- Reduces straight upstream/downstream pipeline requirements
