Multi-rate Tariff
    To realize the multi-rate tariff, the problems that must be solved are self-synchronizing of the system clock and setting & adjusting the time-of-use remotely. In the face of thousands of customers, it is impossible to set system clock and adjust the time-of-use by manual work. So it is necessary to use system. AMR is the best method to solve the problems.

AMR must possess strong management functions
    It is uneconomic for investors to invest substantive capital only to solve the problem of meter reading. AMR must possess strong management functions in order to solve the management problems that cannot be solved effectively by manual work, such as: power line losses analysis, phase power balance, power failure, abnormal power consumption, load profile data, arrearage treatment and so on.
