Alia Variable Area Flowmeters
AVF250 Series
ALIAVA AVF250 Series is a flowmetercommonly 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
