Protect your hydronic heating and cooling systems from flow-related damage with the 120160 FS7-4S flow switch from McDonnell & Miller. This robust flow-sensing device is designed to monitor liquid movement in pipelines, providing an electrical signal when flow starts or stops to ensure system safety and efficiency. Built with premium materials for longevity, the FS7-4S is a trusted component for demanding HVAC and process piping applications.
This flow switch utilizes a paddle-actuated mechanism that sits directly in the media stream. When fluid moves at a specified rate, the paddle deflects, mechanically actuating a precision-engineered switch inside the housing. This simple yet reliable design provides consistent feedback to your control system, alerting operators or automating equipment shutdown if flow conditions fall below safe operating levels.
Key System Performance Baselines:
- Durable Construction: Heavy-duty stainless steel body resists corrosion in harsh industrial environments.
- Positive Actuation: Precision switch mechanism ensures reliable signaling across varying flow rates.
- Broad Compatibility: Engineered for seamless integration into standard 1-1/4" pipe configurations.
- Versatile Application: Suitable for use in liquid-based cooling, heating, and process control loops.
⚠️ Application Profile: Ideal for monitoring flow in industrial chillers, hydronic boilers, liquid distribution headers, and critical cooling pump circuits where equipment protection is vital.
