PCT No. PCT/SE81/00163 Sec. 371 Date Jan. 26, 1982 Sec. 102(e) Date Jan. 26, 1982 PCT Filed Jun. 4, 1981 PCT Pub. No. WO81/03541 PCT Pub. Date Dec. 10, 1981.This invention relates to an electricity meter mainly intended for measuring, registration and reading of one or more consumers' electricity power consumption and/or energy consumption. To the electricity meter a display (12) is connected which is adapted to indicate momentary power consumption, present electricity tariff and accumulated energy consumption expressed in monentary units. The electricity meter is an electronic construction and includes a central processing unit (1) with a microprocessor, one sensor(2) intended for detecting of a consumer's power consumption and a number of memory cells (1a-52d) adapted in a predetermined manner to consecutively receive and store information, calculated and transferred by the central processing unit (1). The electricity meter is also adapted to be connected to a read unit (5) by which stored information and electricity tariffs can be transferred to a central computer, located at, for example, an electrical power producer. |
