The utility model relates to an intelligent electric meter for shared use by multiple users but individual household measurement. The utility model comprises a sampling circuit and a measuring circuit, wherein, the sampling circuit is composed of a divider resistance, a sampling resistance and a switch, and the sampling circuit provides sampling voltage and sample rate current for the measuring circuit; the measuring circuit comprises a multiple-way entry switch, a wave detector, an analogue-to-digital converter (ADC), a memory for storing transmitted data, a display, a control processor (CPU), and a read-only memory (ROM). The electric voltage and the current order of each user are scanned to be sampled and are calculated house-to-house by the multiple-way switch, so that the utility model can realize the function of shared use of one electric energy meter by multiple users and individual household measurement.
