Water flow sensor consists of a plastic valve body, a water rotor, and a hall-effect sensor.
Water flow sensor consists of a plastic valve body, a water rotor, and a hall-effect sensor. When water flows through the rotor, rotor rolls. Its speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse Signal.

i need 1 piece of this pls Bring me one ASAP
Ashikruet | Feb 12,2015 at 09:21 PM
Can i measure diesel with it??
A.R | Feb 14,2015 at 09:49 AM
And what should I understand by 'measuring'?
Ashikruet | Feb 14,2015 at 03:44 PM
flow of diesel per second.
A.R | Feb 15,2015 at 10:01 AM
No. Water only.

Will you provide lcd display and its microcontroller while delivering it? Thank you.
A.R | May 25,2015 at 10:34 AM
Those should be ordered separately!
Isti_pb | Oct 5,2015 at 02:02 AM
Wrong Info..Pls correct is not G3/4..It is G1/2..And Flow rate range is 1~30lpm not 1~60lpm..Replace this specification with G1/2 specification..

How to interface it with microcontroller? I mean how output change with flow?

Is this product water proof??
A.R | Mar 15,2017 at 10:15 AM
As far as we can understand from its outlook, it does not seem to be waterproof. Please see the documents in the documents section. These are the info we got about this product. Apart from these it's not possible for us to know anything.
