Flow Sensor YF-S401

Other Hardware Sensors
1

Hi everyone,

I am planing to use "YF-S401 Datasheet(PDF) - List of Unclassifed Manufacturers" flow meter for a arduino controlled filling device. My questions are:

1-) Is this sensors are accurate (+- 2% as told so in the datasheet.)
2-) Calibration factor in the data sheet "98 means around 0.17 ml for each pulse" is applicable on every project or changes due to piping, pump selection etc. (i am planing a 5V dc powered pump.)
3-) Does it need to be specific type of pump?
4-) Can you give an advice for example code? (need to be sure i read accurate results besides coding.)

Thanks in advance.

Your posted link does not go to an actual data sheet. Please include a link to the ACTUAL data sheet for YOUR device.
No matter the flow sensor, you will need to calibrate the sensor you you have. Even if the specifications are identical, your plumbing equipment will effect the sensor performance.

Smooth flow like a centrifugal , vane or peristaltic pump should be OK, pulsating flow from a piston or diaphragm pump probably not.

Hello emiroztekin

Count pulses per unit of time using an interrupt service..
