A while back I was able to get this type of flow meter to work with OpenSprinkler:
The meter has a hall effect sensor inside that generates clicks which can be detected by a hardware counter pin (using a counter pin is more efficient than polling or interrupt). However, my understanding is that this type of flow meter is not inline, and it’s better to use a proper flow meter like this one:
I think they work the same way, but I haven’t had time to verify it yet.
