Specification

Description

YF-S201 Water Flow Sensor is a light, nimble outline, small in size, and easy to install. The bearings are used in the rotating part. It is Waterproof, heat resistance, pressure resistance, cold resistance. The hall effect sensor is sealed from the water pipe and allows the sensor to stay safe and dry.

This is YF-S201 Water Flow Measurement Sensor with 1-30Liter/min Flow Rate white sensor. This sensor sits in line with your water line and contains a pinwheel sensor to measure how much liquid has moved through it. There’s an integrated magnetic hall effect sensor that outputs an electrical pulse with every revolution. The hall effect sensor is sealed from the water pipe and allows the sensor to stay safe and dry.

Different product model, works well

The product I received was actually the FL-608 and not the FL-408 as specified in the product information here. It has slightly different stats but so far I am able to read the pulses in my test setup. I have not hooked it up to actual liquid flow yet to calibrate it but I believe it will work well for my situation.

Works just fine

Calibration formula incorrect

Got it to work. After testing and calibrating I found that using 6.5 instead of 7.5 as the multiplier gave much more precise readings. Anyone agree?

Accurate, reliable.

Works very well and accurate. Added 0.1 cap on input for noise.

No Dead Spots

Love this ... unlike magnetic reed switch sensors this wont stall in a polarized location giving a false impression of flowing. it is also very sensitive to low flows which a reed switch cant do unless there is a threshold flow
