- Lightweight and compact with stable performance for easy integration - Flow-activated magnet and reed switch: When water flows through the pre-set channel, the magnet is displaced to actuate the reed switch and signal flow. If there is no water flow, no actuation occurs - Versatile compatibility: Thread is G1/4 inch, suitable for use with water dispensers, water purifiers, water vending machines, and similar equipment - Technical specifications: Thread: G1/4 inch; Startup flow: 300 ml/min; Response time: less than 1 second - Practical use scenarios: - In a household water dispenser to trigger downstream components or monitoring when water is drawn - In a water purifier system to control flow-based stages such as pre-filtering or post-filter signaling - In commercial beverage machines or water vending equipment to monitor flow and coordinate dosing or cycle control
