This is the 15V variant of the Water Flow Sensor (Sea) YF-B6 Flowmeter with Temperature Probe G3/4 1-30L/min 5-15V Brass in Water TDS, pH, Flow, Level and Pressure Sensor. Available at ₹775.26 (₹657.00 + GST) with free shipping across India.
Water Flow Sensor (Sea) YF-B6
The water flow sensor consists of a plastic or brass body housing, a water rotor, a Hall-effect sensor, and a PCB electronics board.
Performance: As water flows through the rotor, it spins, with the speed of rotation varying according to the flow rate. The magnetic field from the rotor interacts with the Hall-effect sensor, generating a corresponding pulse signal.
This flow sensor is ideal for applications like water dispensers and coffee machines, providing accurate flow measurement.
