Think of a water meter as a tiny accountant with a job you never wanted. Its only mission? To count every single drop that flows into your pipes. No judgment if you take a twenty-minute shower—this device just logs the data.
The brilliant part? It does all this without any batteries or electricity in most cases. Yep, it’s powered by the water itself as it rushes by. That’s basically free labor, courtesy of your plumbing.
So how does a box with no brain track a liquid? It uses clever physics and a spinning gizmo that would make a pinwheel jealous.
