ATF80 : Smart Target Flowmeter
เนื้อหา



ATF80 Series

The Alia ATF80 Smart Target Flowmeters revolutionizes the target deflection method of measuring flow. The target displacement is precisely measured by capacitance sensors. The resultant signal is then digitally processed via surface-mount, industrial signal processing to Produce a 4-20mA output proportional to the volumetric flow rate.
Smart Target Flowmeter are suitable for low-velocity & high-temp. gas, steam flowrate. Re-ranging the meter is as simple as changing the target. There is no need to change the whole meter.

FEATURES

 ● Measure low velocity less than 0.1 m/s
 ● Measure high-temp., low-press. and low-velocity flare gas.
 ● 4-20 mA output Hart communication
 ● Low Pressure drop
 ● The Max. temperature can be up to 450 ¡ãC
 ● Online calibration by Alia unique software
 ● Insertion Type or Hot-Tap Type available for large pipeline
