This high-performance liquid flow switch is designed to monitor flow or no-flow conditions in pipes by utilizing a paddle-actuated mechanism. The McDonnell & Miller 114763, also known by the model FS5-D-3/4, is engineered for industrial and commercial hydronic applications where dependable signaling is required for pumps, chillers, or cooling systems.
The unit operates by inserting a paddle into the pipe stream, which moves as liquid flow pushes against it. This movement activates internal micro-switches, providing an electrical signal change. With its dual SPDT switch configuration, this device allows for simultaneous control of multiple circuits or redundant safety monitoring, ensuring your system responds accurately to changes in flow velocity.
Key System Performance Baselines:
- Switch Configuration: Includes two SPDT switches for versatile circuit control.
- Connection Size: Standard 3/4-inch NPT pipe connection for seamless integration.
- Reliability: Engineered for consistent, long-term operation in demanding fluid environments.
⚠️ Application Profile: Ideal for use in commercial HVAC, water treatment, booster pump systems, and industrial processing lines requiring precise flow detection and interlock protection.
