RFO-PW Potable Water Rotorflow

RFI-PW Potable Water Rotorflow


The RFO-PW Series is a FDA-compliant rotor and body for compatibility with potable water applications. 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. The RFO-PW Potable Water Rotorflow features a VDC pulsed output for potable water applications where a flow rate monitoring sensor is needed.
