The Xylem-McDonnell & Miller FS4-3 Liquid Flow Switch model 310451 functions as an safety element in HVAC and industrial fluid systems. The device operates through flow monitoring to activate an electrical switch when the flow rate reaches a predetermined threshold. The stainless steel paddle kit of this device supports four standard pipe sizes including 1", 2", 3" and 6" which makes it suitable for diverse installation requirements. Boilers along with chillers and process piping systems use this device to protect their equipment by maintaining sufficient fluid movement. The device detects paddle movement which occurs due to fluid movement.

The FS4-3 uses a single-pole, double-throw (SPDT) switch mechanism to provide dependable electrical control signals based on fluid flow conditions. This switch accurately detects flow status, allowing for precise control and regulation of equipment operation. The Xylem-McDonnell & Miller FS4-3 Flow Switch is designed for long-term reliability, even in the most demanding environments. Its simple installation and user-friendly operation make it an excellent choice for fluid flow monitoring and control applications in industries such as HVAC, plumbing, and industrial processes. This flow switch demonstrates Xylem-McDonnell & Miller's dedication to fluid control solutions that are high in quality, dependability, and innovation.
Key Features for FS4-3 Xylem-McDonnell & Miller 1 Inch Flow Sw.160 Spdt 114400
Pipe Size: 1 Inch National Pipe Thread (NPT). This indicates the diameter of the pipe threads it connects to.
Switch Type: SPDT (Single Pole Double Throw). This means the switch has one electrical input (common) and two output contacts. The switch physically flips between these two outputs depending on whether flow is detected or not. This allows the switch to control two separate circuits based on the flow state (on/off).
Universal Design: While the specific pressure rating and material composition are not available from the model number alone, the FS4-3 is designed for general-purpose applications across various liquid flow control systems.
Signs of a Faulty Xylem-McDonnell & Miller FS4-3 1 Inch Flow Sw.160 Spdt 114400:
Equipment Stopping/Starting Erratically: The switch malfunctioning and sending incorrect flow signals could cause erratic on-off cycles in connected equipment.
Downstream Equipment Not Starting: Equipment that relies on flow to function, such as pumps, burners, or other machinery, might not start if the flow switch malfunctions and fails to detect sufficient flow even when it's present.
Equipment Stopping/Starting Erratically: The switch malfunctioning and sending incorrect flow signals could cause erratic on-off cycles in connected equipment.
