Flow Rate Monitoring – RFA Types
0 to 10 VDC Analog Output
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.
