RFS Type Electronic Flow Sensor
Brand: Gems Sensors, IncRotorFlow 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.
Features- Combines visual confirmation of flow with dynamic, electronic switch operation
- Easy, adjustable switch point calibration: a local LED signals when set point is reached
