Description of the Related Art The meter reading of a water meter is performed by a meter reader reading the scale of the water meter directly by turning around one house at a time. Such a meter reading by a meter reader requires a lot of manpower and time, and therefore, introduction of an automatic meter reading system capable of automatically reading the meter is awaited. When this automatic meter reading system is adopted, since the water meter is installed underground, the signal indicating the amount of tap water usage detected by the water meter cannot be directly transmitted to the meter reading center, and is once sent to the water pipe in each home. The signal will be transmitted through the underground to the installed ground repeater via a signal line, and then transmitted from the ground repeater to the meter reading center.
