RFO Type Electronic Flow Sensor
Brand: Gems Sensors, IncGEMS 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.
RFO Types feature a 4.5 to 24 Vdc pulsed output.
Features- 4.5 to 24 VDC Pulsed Output
