The McDonnell Miller FS1 1/2 Flow Switch, model number 113200, is a robust and reliable instrument designed for monitoring fluid flow in various industrial applications. This flow switch is engineered with a 1/2-inch NPT thread connection, making it compatible with a wide range of pipe sizes and systems.
The McDonnell Miller FS1 is an electromechanical switch that operates on a simple principle: when fluid flows through the switch, the internal float or paddle is moved, thereby completing or breaking the electrical circuit. The switch is available in various configurations, including normally open (NO) and normally closed (NC), to suit different system requirements.
The switch is constructed from high-quality materials, ensuring durability and resistance to corrosion. The float is made of polypropylene, a material known for its chemical resistance, while the body of the switch is made of brass, a material known for its strength and corrosion resistance. The switch is also sealed to protect against moisture and debris, ensuring reliable operation even in harsh environments.
The McDonnell Miller FS1 1/2 Flow Switch is designed to provide accurate and reliable flow detection, with a hysteresis of less than 2% and a repeatability of less than 1%. This means that the switch will consistently detect flow changes, minimizing false alarms and ensuring that system failures are identified promptly.
The switch is easy to install and maintain, with a simple mechanical design and no moving parts that require lubrication. The float or paddle can be easily adjusted to set the flow point, and the switch can be mounted in any orientation, making it flexible for use in a variety of applications.
In conclusion, the McDonnell Miller FS1 1/2 Flow Switch is a reliable and durable instrument for monitoring fluid flow in industrial applications. Its simple design, high-quality construction, and accurate operation make it an excellent choice for applications where reliable flow detection is crucial.
