動発電式水道メータの発信装置。 The water meter main body is provided with a transmitter case that incorporates a transmission mechanism and a power generation mechanism for transmitting power from the flow rate measuring section via a magnetic coupling, and the power generation mechanism is rotated in intermittent fast forward motion in conjunction with the transmission mechanism. Along with this, the N pole and S pole are centered around the axis.
A rotor with symmetrical poles, an iron core installed next to the rotor and perpendicular to the rotor, an electromagnetic coil wound around this iron core, and an electromagnetic coil installed extending from both ends of the iron core. The rotor is characterized by comprising a pair of cores having N and S poles facing each other along the outer peripheral surface of the rotor, and one of which is made large so as to cover approximately half the circumference of the rotor, making it asymmetrical. Automatic power generation water meter transmitter.
