The Gems RFO series is a paddlewheel designed flow meter that combines high visibility rotors with solid-state electronics. Packaged into compact, panel mounting housings, the RFO series provides accurate flow rate output with integral visual confirmation and an unprecedented price/performance ratio.

The RFO series has port sizes from 1/4" to 1" NPTF for liquid flow rates from 0.10 to 60 GPM. Featuring rugged brass, stainless steel or polypropylene construction, the RFO utilizes a simple and reliable design suitable for operating temperatures to 212°F and line pressures to 200 psig. The meter features 4.5 to 24 VDC pulse output. The pulse rate is dependent upon flow rate, port size, and range.
