Gems Sensors Flow Sensor
The Gems Sensors RFS series rotor flow electronic sensor sense a liquid flow rate of 0.5gal/min to 5gal/min. It is built on an extra level of reliability and protection to your equipment. By the principle of operation, the rotor cannot be deceived into indicating a positive flow situation in case of no flow. Once set to a desired actuation point, the rotor flow will switch to a ’no-flow’ condition should the rotor stop for any reason. It has an input power of 24VDC.
