Maintain precise control over your hydronic heating or cooling systems with the McDonnell & Miller 114780 FS5-1 flow switch. This critical component is engineered to accurately detect liquid flow, ensuring that equipment only operates when necessary to prevent dry firing or circulation failures. By integrating this 1-inch flow switch into your plumbing infrastructure, you ensure seamless automation and protection for your pumps, boilers, and heat exchangers.

The FS5-1 functions by utilizing a paddle mechanism that reacts to the kinetic energy of the fluid within the pipe. When flow is detected, the paddle deflects, mechanically actuating a snap-action switch that completes or breaks an electrical circuit to your system controls. This durable, time-tested design provides immediate feedback, allowing for responsive system monitoring and enhanced operational longevity.

Key System Performance Baselines:

  • Durable Construction: Built to withstand rigorous industrial and commercial piping environments.
  • Precise Detection: Engineered for sensitive and repeatable flow actuation.
  • Reliable Integration: Provides seamless compatibility with standard 1-inch plumbing connections.

⚠️ Application Profile: Primarily utilized in commercial hydronic boilers, chiller systems, liquid transfer processes, and high-capacity water heating loops to provide essential flow proofing for automated equipment cycles.
