水道メータ。A driven magnet that transmits the rotation of the drive magnet of the measuring section through magnetic coupling, a tooth train that decelerates the rotation of this driven magnet, a reverse rotation stop mechanism installed in this tooth train, and a single tooth train that allows winding. A transmitter that has a spring that stores energy during rotation, an intermittent feed mechanism that releases the energy of this spring every fixed rotation of a gear train, and a generator that is intermittently driven by the intermittent feed mechanism to generate a unit flow rate pulse. and a remote indicating water meter, which is connected to the coil of the generator of the transmitter by two electric wires, and comprises a transmitter and a receiver installed at a remote location, the driven magnet or the rotation axis of the driven magnet. A magnetoresistive element or a contact element is placed in close proximity to another magnet provided in the transmitter, and one terminal of the magnetoresistive element or contact element is connected to one of the two electric wires within the transmitter. and the other terminal is connected to a separate electric wire and extended to the receiver, and the receiver is connected to each end of a separate electric wire from the one electric wire for external connection. A power-generating water meter characterized by having two terminals.
