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.
Features
- 2 Integral sensors reduce external vibration / frequency interference

- Adjustable display / readout (90o, 180o, 270o, 360o) Simple adjustment
- Battery powered, or external DC powered
- Reduced pressure loss due to internal piping configuration
- Reduced upstream / downstream straight pipe requirements
