Visual Indication, Continuous Sensing and Accurate Switching

With available measurement ranges from 0.1 GPM to 60.0 GPM (0.4 LPM to 227 LPM), the Gems RotorFlow line features a unique paddlewheel design which combines high-visibility composite rotors and durable solid-state electronics. RotorFlow sensors are organized into three distinct types. These include Switch (RFS), Output (RFO and RFA) (DC and analog), and Indicator (RFI) Types.

• RFS Types allow for specific flow set point switching, which is fully adjustable over the specified flow range. The dynamic operation of the electronic rotor itself prevents jamming and false actuation. Once set to a desired actuation point, an RFS Type sensor will switch to a “no-flow” condition, should a rotor stop moving. A local LED signals when a set point has been reached.
• Gems RotorFlow RFO and RFA Type sensors offer flow rate measurement accuracy and integral visual indication. They are easily integrated into most digital logic units. RFO Types provide a 4.5 to 24 VDC pulsed DC voltage output that is directly proportional to measured flow rate, while RFA Types provide a continuous 0-10 VDC analog output.
• RFI Types offer effective, “at-a-glance” flow rate estimation and confirmation, with easy viewing of the run speed of the brightly orange colored, single-piece composite rotor. RFI Types are available with choice of bright orange or bright blue rotor.
