An ISO-9001 registered company and the "home of the Flo-Gage™"

RCM Industries manufactures flow meters for measuring the flow rate of  liquids, gases, compressed air and steam in closed pipes. We also make indicating flow switches and flow transmitters for process indication and control. Meters feature a large easy to read analog dial with 270 degree pointer movement.

Our meters are suited to a wide range of applications where affordability, reliability and ruggedness are important considerations.

Advantages

• Provides flow rate indication similar to a rotameter in a much easier to read and install design
• Available in pressures to 400 psig and temperatures to 350^o F.
• Large easy-to-read 3.5" dial with 270^o pointer rotation.
• Black-on-white dial won't crack, craze or become difficult to read with age
• Mount in any position - vertical, horizontal or in between
• Reads directly in engineering units - no conversions required
• Readings repeatable to +/- 1% F.S.
• Measures gases, liquids, steam, oils, refrigerants and many others
• Measures both clear and opaque liquids
• Sturdy all metal in-line construction resists piping stresses and strains without breaking
• Liquid flow ranges from 4 GPH (1/2" meter) to 3,000 GPM (8" meter)
• Metric liquid flow ranges from 15 l/h (1/2" meter) to 12,000 l/m (8" meter)
• Gas flow ranges from 40 SCFH (1/2" meter) to 20,000 SCFM (8" meter)
• Metric gas flow ranges from 1 Nm3/h (1/2" meter) to 600 Nm3/m (8" meter)
• Measures 6:1 flow range with 3% F.S. accuracy
• Can be fitted with optional transmitters or limit switches

Applications

The Flo-Gage™ has been developed for industrial applications where durability and reliability are important considerations in the monitoring of flow. The Flo-Gage™ has accuracy for most industrial processes and is particularly suited for applications where compactness, low cost, minimal maintenance and resistance to accidental damage are important factors.

Typical applications include cooling water, lube oil monitoring, cutting oil monitoring, blending processes,  reverse osmosis systems, welding gas and compressed air measurement.

Operating Principle

All of our meters operate on the differential pressure principle. The flowing fluid travels through a proprietary orifice, creating a pressure difference between the pressure at the meter inlet and the pressure in the orifice. This difference is detected by a pair of miniature bellows and converted into a pointer movement indicating flow rate.

This measuring method provides many advantages. Readings are made directly on the dial in engineering units with no conversions needed. No flow passes through the bellows or through small orifices making the meter less susceptible to plugging and sticking than rotameters and most other mechanical meters and flow switches.
