ALIA 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 .
