Variable Area Flowmeter
AVF250 Series

ALIAVA AVF250 Series is a flowmeter commonly used in Auto-industry process control. It’s with small volume, wide range and easily operation. It could also measure liquid, gas and steam flowrate, especially fit for small flowrate application.
FEATURES

 4 digit flowrate & 8 digit totalizer
 Local indication without auxiliary power
 4-20 mA & Scale pulse output
 Low pressure lost on gas and steam application
 Damper for Gas/Steam application
 Consistent overall length
 Heating jacket design
 Intrinsically safe & explosion proof for hazardous area
