Metal Tube Variable Area  Flowmeter

ALIAVA AVF250 Series


Metal Tube Variable Area Flowmeter



Details

The Alia AVF250 flowmeter is commonly used in location that required on-site analog flow indication. The meter accurately measures small volumes / wide ranges of liquids, gases and steam.

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