Clamp on water flowing sensor / Clamp on water flowing switch

Hi,

I want to measure if there is water flowing in my water supply pipes (both cold as hot). I do not need to know how much just if its flowing or not.

I do not want to change any of the piping so I want to be able to clamp it on a pipe and connect it to a Shelly Uni Plus.

Does anyone of you know where I can find this or maybe build it yourself? Most likely it has to be done with some kind of ultrasonic solution.

Thanks.
PS: I use the word “flowing” because it is impossible to use the word “flow” :grimacing: :sweat_smile:

Found this really cheap (!!!) Digital Ultrasonic Flowmeter Module at Ali. But I don’t know if it’s possible to use it in combination with the Shelly One Plus. I guess you mean the Shelly Plus Uni, aren’t you?

This uses a clamp and uses ultrasonic measuring. But it’s not available yet :face_with_peeking_eye:
And, it does measuring next to flow detection
