RCM - Threaded Liquid FlowmeterThe RCM is a differential pressure directreading flowmeter. It is suitable formonitoring all liquids and gases that havelow or medium viscosity, low solidscontent, and are compatible with thematerials of construction. The meterfeatures rugged, compact construction. Inliquid applications of 6 GPM and higher,pulsation snubbers are incorporated intothe connecting pressure passages toproduce smooth meter operationindependent of pipeline turbulence.This meter was developed for industrialflow metering applications in whichdurability and reliability are importantconsiderations. Accuracy, small size, lowcost, minimal maintenance and resistanceto accidental damage are the prime goalsin the RCM design. Typical applicationsinclude: lube oil and cooling watermonitoring, blending processes, reverseosmosis systems, and compressed airmeasurement.The RCM is available with a 4–20 mAoutput for interfacing with remote displaysand controllers. Limit switches areavailable to provide high and low limitsignals. A 0–1000 Hz frequency output isavailable to drive frequency basedcontrollers and counters.SpecificationsAccuracy: 3 % Full ScaleFlow Media:Liquids and GasesMounting:Horizontal or VerticalMedia Temperature RangeStandard:- 30 to 212 FOptional:- 80 to 350 F(without electrical options)Maximum PressureStandard:180 PSIGOptional:400 PSIGHousing:PolycarbonateUV stabilizedBody:Bronze, Monel,or 316 SSOption -ES: also TeflonTMBellows:Bronze, Monel316 SS or InconelTMMovement:Bronze or SSSeals:Buna-N, Viton ,EPDMor TeflonTMCrystal:PolycarbonateRelay Options: High/Low AlarmsOutput Options: 4–20mA0–1000 Hz FrequencyModel RCM-7126Subject to change without prior notice.

We recommend that valving, if required, be installed downstream ofthe flowmeter.The gas flow meters (Models 6000 and 9000), are inlet pressure sensitive. To operateproperly, the gas pressure at the inlet of the meter must be regulated to a constant,user-selected value.
