Deskripsi

ALIAVA Metal Tube Variable Area Flowmeter AVF250

GENERAL Variable Area Flowmeter AVF250

ALIAVA AVF250 Series is a flowmeter commonly usedin Auto-industry process control.
It’s with small volume, wide rangeand easily operation.It could also measure liquid,
gas and steam flowrate, especially fitfor small flowrate application.
