    • PROBLEM TO BE SOLVED: To develop a water stream sensor which does not generate a mulfunction due to external disturbance.
      SOLUTION: The water stream sensor 10 is provided with: a downstream side bearing member 26; an upstream side bearing member 40; and an impeller-like magnetic generation member 28 in a casing 25, and is also provided with two magnetic sensors 30, 31 at the outer circumferential part of the casing 25. The first magnetic sensor 30 and the second magnet sensor 31 are located off by 22.5° (π/8). Because of the positional relationship where, when the first magnetic sensor 30 is in a peak environment so as to be turned on, the second magnetic sensor 31 is in an environment of a transitional region so as to be switched from the on-state to the off-state or a transitional region so as to be switched from the off-state to the on-state, the first magnetic sensor 30 functions normally in an operational environment in which the second magnetic sensor 31 is unstable.

    • PROBLEM TO BE SOLVED: To provide a water meter system capable of making attachment and removal operations of water meters more efficient than before. SOLUTION: By this form of implementation, since it is possible to simultaneously open and close both end part channels 12 and 13 of upstream-side and downstream-side of a water meter 20A by the one operation of moving a movable member 30A between first and second positions, it is possible to perform attachment and removal operations of the water meter 20A more efficiently than before. Since the movable member 30A functions as a water-stop part when the movable member 30A is arranged at a water-stop position to prevent service water from flowing inside the movable member 30A from both the upstream side and the downstream side from the water meter 20A, the discharge of service water from an intermediate metal fixture 10A is prevented after the removal of the water meter 20A.

    • 要解决的问题:提供能够使水表的附着和拆卸操作比以前更有效的水表系统。 解决方案:通过这种实施方式,由于可以通过移动可移动部件30A的一个操作来同时打开和关闭水表20A的上游侧和下游侧的两个端部通道12和13 在第一和第二位置之间,可以比以前更有效地执行水表20A的附接和移除操作。 由于可移动部件30A在可动部件30A配置在停水位置时起到止水部的作用,从而能够防止维护水从水表20A的上游侧和下游侧向可动部件30A内流动 在去除水表20A之后,防止来自中间金属固定装置10A的使用水的排放。 版权所有(C)2007,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a flowmeter having higher measurement precision than before. SOLUTION: By the flowmeter 10 of this invention, it is possible to heighten measurement accuracy more than before by reducing the amount of overhang of a flange part 80 provided for a rectifier 20 as it separates from an inflow opening 11A of a meter case 11 and widening a gap on the farther side from the inflow opening 11A among gaps between the circumferential surface of the flange part 80 and the inner surface of the meter case 11 more than that of a conventional device.
