- For hydroponic setups, solar heating circuits, and factory machinery where steady liquid flow and automatic pump shutdown on anomalies are essential. - Precision flow detection and automatic shut-off: this flow switch with G1/2 threaded interfaces ensures accurate water flow sensing and instantly activates circuit protections against pump dry running, safeguarding equipment with leakproof performance. - Easy installation: tool free mounting and clear wiring guides let this flow switch integrate into existing pipelines for immediate operation without complex configurations. - ABS construction and corrosion resistant G1/2 port withstands pressure while maintaining sealing, ideal for long term use in liquid media including cold and hot water systems. - Fits standard G1/2 piping and is suitable for a range of applications requiring reliable flow control and pump protection. Use scenarios - In a hydroponic irrigation loop to automatically shut off the pump if flow drops, preventing root damage and water waste. - In solar thermal heating systems to stop pumps when abnormal flow is detected, reducing energy use and preventing overheating. - In industrial cooling or process lines where consistent flow and leakproof operation are critical to protect equipment and minimize downtime.
