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.
FEATURES Variable Area Flowmeter AVF250
- 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
