PROBLEM TO BE SOLVED: To provide a water meter system wherein the water consumption except for pre-set reverse-flow component is acquired even if a water meter is connected reversely. SOLUTION: A reverse-flow counter which counts a reverse-flow amount at a water meter 1 at a control means wherein no integration is displayed at a reception part 12 until the reverse-flow amount exceeds a specified amount, after which it is displayed even for the reverse-flow, are provided. The reverse- flow counter and the control means are comprised in a microcomputer 8 of a transmission part 5. When letting the reception part 12 display integration at reverse flow, a pulse different from a voltage pulse for operating a stepping motor 14 is outputted as well.
