Gems Sensors Flow Sensor


The Gems Sensors RFS series rotor flow electronic sensor sense a liquid flow rate of 2L/min to 20L/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.

Features and Benefits


Pipe diameter range is 1/4in
Combines visual confirmation of flow with dynamic, electronic switch operation
Easy, adjustable switch point calibration- a local LED signals when set point is reached
It is available in polypropylene body material
Connection type is 1/4 BSP female
Maximum operating pressure is 7bar
Maximum operating temperature is 80°C

Applications


Semiconductor processing equipment
Lasers
Medical equipment
X-Ray and other high-power tubes
Robotic welding equipment
