The Dwyer IF2718 is a Series IF industrial direct reading variable area flowmeter rated to 60 GPM (227 LPM) of water and 245 SCFM (6938 LPM) of air on a dual GPM and SCFM scale that reads flow directly, with no correlation charts. It installs vertically through 2 in. female NPT connections.
Best For
- Gas or liquid metering up to 60 GPM water or 245 SCFM air
- Industrial pneumatic or hydraulic systems
- Lines with 2 in. female NPT connections
- Process conditions up to 125 psi and 200°F (93°C)
Warranty
1-year limited warranty from delivery to the buyer under the DwyerOmega standard warranty.
Key Features
