Flow Rate Monitoring – RFA Types



GEMS Sensors popularized the RotorFlow’s paddlewheel design by combining high

visibility rotors with solid-state electronics that are packaged into compact, panel

mounting housings. They provide accurate flow rate output with integral visual

confirmation...all with an unprecedented price/performance ratio. RFA Types feature a

0 to 10 VDC analog output which is proportional to flow rate.
