PROBLEM TO BE SOLVED: To provide a water meter system capable of preventing water discharge from an intermediate metal fixture, when a water meter or a check valve are dismounted, while the intermediate metal fixture is connected to a water pipe. SOLUTION: In this water meter system 100, when a rotary cylinder part 30 is rotated and arranged on a water stop position, the interval between each end channel 12, 13 provided in each intermediate metal fixture 10 and each relay channel 35, 32A provided in the rotary cylinder part 30 is blocked, to thereby prohibit inflow of service water into the rotary cylinder part 30. When the water meter 20 is dismounted from the rotary cylinder part 30 in this state, water is not discharged from the intermediate metal fixture 10, even if the intermediate metal fixture 10 is still connected to the water pipe. Water is not discharged also from the intermediate metal fixture 10, even when the check valve 38 is dismounted. COPYRIGHT: (C)2008,JPO&INPIT
