RotorFlow RFS

November 01, 2019




This unit combines visual confirmation of flow with dynamic, electronic switch operation. Easy, adjustable switch point calibration – a local LED signals when set point is reached. 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. Typical applications include protection of expensive electronic equipment from coolant flow failure on Semiconductor Processing Equipment, Lasers, Medical Equipment, X-Ray and Other High Power Tubes, Robotic Welding Equipment
