Series FS6 Switch Liquid Flow

McDonnell & Miller FS6 liquid flow switches are designed to monitor the flow of liquids, such as water or oil, in pipes and systems. These liquid flow switches are highly sensitive and used in cooling systems, booster pumps, water treatment systems and compressors. They have a sealed compartment that protects the switch from liquids and a sensitivity adjustment screw to prevent false tripping of the flow switch. These liquid flow switches serve as a crucial safeguard, preventing damage and potential hazards caused by insufficient or excess liquid flow. They can be operated at temperatures ranging from 32 to 225 degrees F and can withstand pressures up to 100 psi. These liquid flow switches are integrated with an SPDT switch for monitoring the direction of liquid flow.
