WATER FLOW SENSOR YF-B4:
Water flow sensor consists of a copper body, a water rotor, and a hall-effect sensor. When water flows through the rotor, rotor rolls. Its speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse signal. This one is suitable to detect flow in water dispenser or coffee machine.
Life is longer than plastic body.
Features:
• Compact, Easy to Install
• High Sealing Performance
• High Quality Hall Effect Sensor
• RoHS Compliant
