ALIAVTX - The ASF7100 Series Swirl Flowmeter (Lưu lượng kế kiểu xoáy)



GENERAL


The ASF7100 Series Swirl Flowmeter is a gas flow meter that combines turbine & vortex flow measurement technologies to provide a reliable, high accuracy, robust, maintenance free flow meter. The turbine-shaped flow inlet causes the process flow to rotate causing a vortex core to form & a subsequent secondary rotation causes thread-like spirals to be formed. 

These resulting secondary pressure frequencies are linear & proportional & are measured by dual piezo-electric sensors. The resulting measurements are processed & pressure & temperature compensated and then converted to the flow measurement display. ASF7100 Series Swirl Flowmeter can be widely used in petroleum, chemical, electricity, metallurgy, coal and other industries.


FEATURES


2 Integral sensors reduce external vibration / frequency interference 

No integral moving parts to ensure steady, reliable and long service life 

Integral temperature & pressure measurement ensuring actual compensation 

Multiple signal O/P's: 4-20 mA, Pulse, RS485, Alarm Adjustable display / readout (90o, 180o, 270o, 360o) 

Simple djustment Battery powered, or external DC powered 

Reduced pressure loss due to internal piping configuration

Reduced upstream / downstream straight pipe requirements
