RCM Flow Meters
Flo-Gage™ Direct Reading Flow Meters · Flo-Gard™ Flow Switches
The RCM Flo-Gage™ is a direct reading flow meter with a large, easy-to-read 3.5" (90mm) 270° analog dial calibrated in engineering units (GPM, SCFM, l/min, etc.). It measures flow based on a pressure differential across a built-in calibrated nozzle — self-contained, no external power, no separate orifices or blocking valves required.
Suitable for liquids, compressed gases, and saturated steam. Liquid ranges from 4 GPH to 3,000 GPM; gas from 40 SCFH to 20,000 SCFM. Accuracy ±3% F.S. Available in ½" through 8" meter sizes.
