Flow rate and volume helps tell the amount of fluid going into, or through a particular vessel. For certain process automation applications, this simple-sounding fluid measurement task is so critical to the success of the project that, failure to get it right, could bring the entire process to its knees. This is why for today’s tutorial, I thought it will be cool to look at this nice water flow sensor; the YF-S201, and its use in an Arduino based project.

The YF-S201 water flow sensor consists of a pinwheel sensor that measures the quantity of liquid passing through it.

The sensor uses the principles of electromagnetism, such that, when liquids flow through the sensor, the flow action impacts the fins of a turbine in the sensor, causing the wheel to spin. The shaft of the turbine wheel is connected to a hall effect sensor so that with every spin, a pulse is generated, and by monitoring that pulse with a microcontroller, the sensor can be used in determining the volume of fluid passing through it.
