Gems RotorFlow Flow 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.
How to set the set point of RFS flow switch?
With the unit installed in the line and power supplied, complete the following steps to calibrate switch actuation point with a proper flow rate. A small flat-blade screwdriver is the only tool required.
- Adjust liquid flow in the line to the rate at which switch actuation is desired.
- Insert screwdriver into opening on backside of housing and fit blade into the potentiometric adjustment screw inside.
- If LED is not illuminated, slowly turn screwdriver counterclockwise and stop as soon as LED illuminates.
- If LED is illuminated, turn screwdriver clockwise until LED light goes out. Then, slowly turn screwdriver counterclockwise and stop as soon as LED illuminates.
