The KOBOLD RCM Series differential pressure direct-reading flowmeter is suitable for monitoring compatible liquids and gases having a low to medium viscosity and low solids content. The RCM flowmeter features rugged, compact construction with no moving parts to wear out. In liquid applications of 6 GPM and higher, pulsation snubbers are incorporated into the connecting pressure passages to produce smooth flowmeter operation independent of pipeline turbulence. The RCM flowmeter was developed for industrial flow metering applications in which durability and reliability are important considerations. The prime goals achieved within the RCM flowmeter design are: accuracy, small size, low cost, minimal maintenance and increased resistance to accidental damage. Typical applications include: lube oil and cooling water flow monitoring, blending processes, reverse osmosis systems, and compressed air measurement. The RCM direct-reading flowmeter is optionally available with a 4–20 mA analog current output for interfacing with remote displays and controllers. Limit switches are also available to provide high and low limit signals. In addition, a 0–1000 Hz frequency output is available to drive frequency-based controllers and counters.
