LoFlow® Series J Vane Meters DN 10-25 (3 /8”-1”)

VAF Instruments flowmeters perform liquid measurement with the

highest accuracy.

VAF Instruments positive displacement flowmeters operate on the sliding vane

principle. The meter consists of a specially shaped housing in which a rotor can

rotate freely. Two pairs of vanes are placed into four slots in the rotor. Each pair

is positioned by a rod and can move in and out of the rotor.

The flowmeter is driven by the process liquid which makes it suitable for distant locations without power supply.

VAF Instruments flowmeters are available in sizes from 8 mm up to 300 mm (1 l/hr up to 960


LoFlow® meters are available in connection sizes from 10 mm up to 25 mm representing maximum flow ranges from 20 l/min up to 50 l/min.
