WenZhou bridge Industry zone,Yueqing City,Zhejiang province,China.

1, fee control table is divided into local fee control electric energy meter and remote fee control electric energy meter two kinds. The cost control of electric energy meter to save all the information needs of local billing, electric energy metering and charging in electric energy meter; remote control fee charging electric energy meter in the master / electricity system, electric energy meter is a measuring instrument and control actuator.
2, local fee control table can be divided into two kinds of local prepaid and remote prepaid. The local prepaid card, through the CPU RF RF card prepaid remote solid medium, through the RS485, wireless public network virtual media.
