Determined to provide you with the most versatile line of flow sensors available, we've continued a non-stop refinement process for the entire RotorFlow® Series.  Gems™ new generation of RotorFlow® sensors, the RF-2500 Series flow switch, has been totally re-engineered with a one piece composite rotor, stronger unibody construction, ceramic shaft and better sealing.  The results are greater durability with broader chemical, temperature and pressure capabilities.

Today's RotorFlow® Series is state-of-the art and offers more options, better performance and durability than ever before...all at an affordable price geared for high volume, OEM applications.

Select the RotorFlow® sensor that is right for your application by choosing one of our three distinct configurations.  You'll find details on each of these configurations inside.

RFS Types

RotorFlow®  Switches build an extra level of reliability and protection into your equipment. By principle of operation, the rotor cannot be deceived into indicating a positive flow situation when no flow actually exists. Once set to a desired actuation point, RotorFlow® will switch to a “no-flow” condition should the rotor stop for any reason.

RFA Types

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 and an unprecedented price/performance ratio.

FT-210 Series

Gem's™ FT-210 features proven turbine technology in a small package for low flow applications. The turbine technology provides a highly repeatable sensor ideally suited for measurement of either volume dispensing and/or flow rate applications. The small turbine reacts quickly to on/off dispensing applications. Each sensor is 100% tested, ensuring years of service life. Units are available in Grivory for use in methanol/ethanol.
