Body Material: Polypropylene Port Size: 1/4" NPT Female Flow Range (GPM): 0.1-5.0 Low Flow Accuracy: +/- 7% Standard Flow Accuracy: +/- 7%

GEMS Sensors popularized the Rotor Flow’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. RFO Types feature a VDC pulsed output.
