Flo-Gage™ Direct Reading Flowmeters
The Flo-Gage measures flow using a calibrated internal nozzle that creates a differential pressure proportional to flow rate. This pressure is mechanically translated to a large, easy-to-read dial calibrated in standard engineering units such as GPM, SCFM, l/m, and more.
- No external power required
- No separate orifice plates
- No equalizing, purging, or blocking valves
- Works with opaque fluids
- Field-configurable orientation
No External Power Required
Fully mechanical design — no electrical connections, no power supply needed.
±3% Full-Scale Accuracy
Large 3.5″ (90mm) 270° analog dial with excellent repeatability.
Low Maintenance
Proven mechanical design with long service life and no separate orifice plates.
Fast Delivery
Standard 2–3 week lead time. QuickShip option: 3–4 business days ARO.
