FLOW SWITCHES
FSF series
*INTRODUCTIONS
1. FSF series Liquid Switches are Single-Pole-Double-Throw (SPDT) flow switches that are used in liquid lines carrying water, ethylene glycol, or other liquid not classified as hazardous. They can be wired to energize one device or deenergize powered from the same source when liquid flow either exceeds or drops below the set flow rate.
2. Flow switch cannot be used where the liquid in the pipes will drop below the liquid’s freezing point, causing an internal freeze-up.
3. The rate of the flow switch can be adjustable (with 5 slices stainless steel paddles)
