APF830 Alia Vietnam liquid flow meter

Introducing APF830 Alia Vietnam

The APF830 series is a positive displacement meter designed with a pair of toothed helical rotors, displays the totalizer with a mechanical pointer, and provides a 4-20 mA pulse output. It has the advantages of no pulse generation, low noise, high precision, high reliability, large measuring range and strong environmental adaptability.
APF830 series spiral rotor flowmeter can be used in commercial measurement and technical management control in petrochemical, metallurgy, electronics and other industries.
