Used for flow rate monitoring or metering applications, Gems RotorFlow RFO type fluid flow sensors produce a pulsed 4.5 to 24VDC output proportional to the rate of flow. A visible paddlewheel provides verification fluids are moving. The sensors are offered in 1/4- to 1-in. port sizes, and monitor fluids with flow rates ranging from 0.1 GPM to 60 GPM. Accuracy is typically within +/-7%. Typical applications include water purification, dispensing systems, water injection systems, and chillers and heat exchangers.
