Xylem FS6-1 High Sensitivity Liquid Flow Switch 1 Inch NPT

The Xylem FS6-1 is a high sensitivity liquid flow switch designed for heavy duty applications where instant switching is required, such as water treatment systems, cooling systems for electronic circuits, compressors, booster pumps, and bearing cooling applications. This in-line configuration eliminates the need for a pipe tee and provides very high flow capacity while actuating at extremely low flow rates.

Key Features:

• Single pole, double throw (SPDT) snap switch for reliable operation
• High sensitivity flow range between 0.12 to 2.5 gallons per minute
• 1 inch NPT threaded connections for flow-through installation
• Switch compartment is completely sealed to protect it from the liquid
• Sensitivity adjustment screw for easy flow adjustment
• Maximum operating pressure of 100 psi
• Temperature range: 32°F to 225°F (0°C to 107°C) for both fluid and ambient conditions
• 120 volt operation

The FS6-1 features McDonnell & Miller's proven design for continuous protection against low water conditions and flow interruptions. The NEMA 1 enclosure provides reliable protection in standard industrial environments, while the adjustable sensitivity ensures precise flow monitoring across a wide range of applications.
