Does a mechanical water meter reset to zero after reaching 999,999 m³?
I have a Dorot DN-100 mechanical water meter. Is it true that once the odometer-style register rolls over from 999,999 m³, it mechanically resets and begins counting from zero again — similar to how an old car odometer works?
If so, how can a utility company or technician distinguish a post-rollover reading from a genuine low reading, and is this accounted for in billing systems?
