YF-S201C G 1/2″ Water Flow Sensor Fluid Flowmeter Switch Counter 1-30L/min Meter

Water flow meter model YF-S201C, pipe size 1/2” supports flow rate range 1-30 L/min, suitable for a variety of applications. For example, it measures the flow of coolant in CNC machines or in laser cutters, etc. The function of a water flow sensor is to allow water to flow through the internal impeller to cause rotation. The hall effect sensor detects the rotation and sends a pulse signal. Come out every turn.
