Vortex & Swirl Flowmeter

ASF7100 Series

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.

AVF7000 Series

The AVF7000 Series is a Vortex Flowmeter based on Von Karman's 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. Standard configuration has local indication for flowrate and total flow as well as 4-20 mA with HART signal and pulse output functions. The microprocessor design can filter out erroneous signals as well as interference caused by pipe vibration.
