Flow Rate Monitoring – RFO Type



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. RFO Types feature a

VDC pulsed output.

Typical Applications

• Water Purification/Dispensing Systems • Chemical Metering Equipment

• Lasers and Welders • Water Injection Systems

• Semiconductor Processing Equipment • Chillers and Heat Exchangers

... FLOW OUT 1. As liquid passes through the RotorFlow body, the magnetic rotor spins at a rate proportional to flow. This causes a series of magnetic fields (the rotor vanes) to excite the Hall Effect sensor, producing a series of voltage pulses. 2. The output pulses (RFO) are at the same voltage level as the input (4 VDC) with a frequency proportional to the flow rate ...

... O-rings should be lubricated prior to re-assembly. Low Flow Applications A low flow adapter is supplied with all Rotorflow units used to produce accurate response at low flow rates. Install the adapter, as shown above, in the port selected for incoming flow. ...
