Xylem-McDonnell & Miller FS254 General Purpose Flow Switch NEMA-4 120°-610°F

The Xylem-McDonnell & Miller FS254 Liquid Flow Switch functions as a monitoring product for HVAC systems, hydronic heating and industrial systems to maintain system operation while protecting against low-flow events. This product operates from a NEMA 4 enclosure which delivers resistance against harsh environmental conditions. Such changes trigger system responses via the switch which protect pumps from damage while preserving their operational efficiency. This part operates effectively in boilers and cooling systems and piping networks to protect equipment safety and minimize downtime while enabling high system performance.
