  • Gems RFI Flow Indicator

    Series Indicator Type Media Type Body Material
    RFI Paddle Liquid Brass/Bronze, Stainless Steel, Plastic

    Gems® type RFI indicators are RotorFlow in its most basic form – a bright orange rotor turning with fluid flow. They are simple, direct, and reliable. Flow rate is estimated, or simply confirmed, by viewing the speed of the turning rotor. Either port may be used for incoming flow, and bayonet mounting lens is easily removed for quick cleanout. RFI Type RotorFlow sensors are easy to see, easy to install, and easy to afford.

  • Gems RFS Flow Indicator

    Series Indicator Type Media Type Body Material
    RFS Paddle Liquid Brass/Bronze, Stainless Steel, Plastic

    Gems® type RFS RotorFlow switches build an extra level of reliability and protection into your equipment. Once set to a desired actuation point, RotorFlow will switch to a “no-flow” condition should the rotor stop for any reason. Typical applications include semiconductor processing equipment, lasers, medical equipment, X-ray and other high power tubes, and robotic welding equipment.
