Flow Sensor 1/2 Inch

While Accurate flow measurement is an essential step both in the terms of qualitative and economic points of view. Hence Flow meters have proven excellent devices for measuring water flow. While now it is very easy to build a water management system using the renowned water flow sensor. Hence YF-S201.,Flow Sensor 1/2 inch

Working of Flow Sensor 1/2 Inch

YF-S201 1/2 inch Water Flow Sensor sits in line with the waterline and contains a pinwheel sensor to measure how much water has moved through it. There is an integrated magnetic Hall-Effect sensor that outputs an electrical pulse with every revolution. Thus YF-S201 1/2 inch water flow sensor has only three wires and it can be easily interfaced between any micro controller and Arduino board.

Principle :

When water through the flow rotor assembly. Hence the magnetic rotor will rotate and Speed of rotor will change as the flow change.
Hall current sensor Read the pulses and provide output corresponding pulse signal and feedback sent to the controller.
then the controller will measure the flow and display the value in term of flow speed and total volume passed through the sensor.
these sensors may be used for water heaters, credit card machines, water vending machines, flow measurement devices.

main features are : Flow Sensor 1/2 inch
