AVF250 Series
AVF250 Series
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
- 5 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
