The Gems Sensors RFO series rotor flow electronic sensor sense a liquid flow rate of 2L/min to 20L/min. The sensors popularised the rotor flow paddle wheel design by combining high visibility rotors with solid-state electronics packaged into a compact, panel mount housings. It provides an accurate flow rate output with an integral visual confirmation and an unprecedented price/ performance ratio. The output signal for RFO is an on/off the pulse of the DC voltage supplied to the unit, it is compatible with all digital logic families. The frequency of the output pulse is proportional to the flow rate and ranges from approximately 15Hz to 180Hz.
