APF830 Series

APF830 Series The APF830 series is a positive displacement meter designed with a pair of tooth profile helical rotors, which displays totalizer with a mechanical pointer and provides 4-20 mA or pulse output. It has the advantages of no pulsation, low noise, high accuracy, high reliability, large measuring scope and strong environment adaptability. APF830 series helical rotar flowmeter could be used in commercial measurement and engineering management control in petrochemical, metallurgical, electronics and other industries.
