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

YF-S201C Water Flow Meter (1/2") – High-precision flow sensor for liquids with a range of 1–30 L/min, suitable for CNC machines, laser cutters, and DIY electronics projects. Accurate NPN pulse output for real-time flow monitoring. Available online in Pakistan.

How It Works

The water flows through the internal impeller, causing it to rotate. This generates an NPN pulse signal proportional to the flow rate for accurate measurement.
