Flow meters screw PPV for the oil product account and other liquids, It is used in the marine industry
The principle of action of screw counters of a liquid reminds work and consists in that two screws taking place in gearing rotate under action of a stream of a liquid, measure at each revolution some volume. Rotation of screws through magnetic coupling, is transferred in the accounting mechanism, being transformed to units of volume.
