This is the 15V variant of the Water Flow Sensor (Sea) YF-B7 Flowmeter with M8 Thread NTC50K Sensor G1/2 1-25L/min 5-15V Brass in Water TDS, pH, Flow, Level and Pressure Sensor. Available at ₹725.70 (₹615.00 + GST) with free shipping across India.
Water Flow Sensor (Sea) YF-B7
The water flow sensor features a plastic or brass body housing, a water rotor, a Hall-effect sensor, and a PCB electronics board.
Operation: When water flows through the rotor, it causes the rotor to spin. The speed of rotation varies with the flow rate. The magnetic field from the rotor interacts with the Hall-effect sensor, which then generates a corresponding pulse signal.
This flow sensor is ideal for detecting water flow in applications such as water dispensers or water machines.
