Introducing AVF250H Alia Vietnam
The AVF250H series is a horizontally mounted metal tube variable area flowmeter. With its unique design, it can provide a mechanical pointer display without power supply, as well as being intrinsically safe and explosion-proof to suit various operating conditions.
Features of AVF250H Alia Vietnam
- Spring mounted horizontal metal tube flow meter
- 5-digit flow & 7-digit totalizer
- The local indicator has no auxiliary power
- 4-20 mA and scaled pulse output
- Low pressure loss in gas and steam applications
- Regulator for Gas/Steam applications
- Consistent overall length
- Intrinsically safe & explosion-proof for hazardous areas
