Alia Tube Flow Meter | 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 easy 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 loss on gas and steam application
- Damper for Gas/Steam application
- Consistent overall length
- Heating jacket design
- Intrinsically safe & explosion proof for hazardous area
