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.

水流傳感器由銅體,水轉子和霍爾效應傳感器組成。當水流過轉子時,轉子滾動。其速度隨著流速的變化而變化。霍爾效應傳感器輸出相應的脈衝信號。這適用於檢測飲水機或咖啡機中的流量。
生命比塑料體長。
