The Gems Sensors RotorFlow paddle wheel flow sensors feature a bright orange rotor which is easily visible for manual checking of flow and this is combined with electronics which offer a highly accurate output based on a Hall-Effect sensor. The RFO offers a square wave pulsed output while the RFA extends the package to offer a 0-10V output, both types are available in either polypropylene, brass or stainless steel construction.
