Description
The Xylem-McDonnell & Miller FS7-4SW is a 1.25-inch single-pole, double-throw (SPDT) flow switch intended for usage in difficult conditions. Its robust stainless steel construction and NEMA 4 enclosure make it impervious to dust, water, and corrosion. With a pressure rating of 1000 PSI, this switch is suitable for a wide range of applications. Its operation relies on detecting the presence or absence of water flow. They are often found in HVAC units such as cooling towers, boilers, and chillers, and they are essential to maintaining the effectiveness and safety of the system. By keeping an eye on water flow, the equipment can be protected from potential damage and expensive downtime by setting off alarms or shutting down when there is little or no flow. Its precise flow detection also allows for precise system control, which maximizes energy efficiency and performance.
