An electric meter, or energy meter, is a device that measures the amount of electric energy consumed by a building, tenant space, or electrically powered equipment. Electric utilities use electric meters installed at customers' premises to measure electric energy delivered to their customers for billing purposes
We just processed in a large batch of chipsets. I posted below current inventory and attached pictures of each type of chipset. Please review and let me know your interest/offer.

Single-phase smart watt-hour meter adopts large-scale integrated circuit and dedicated ultra-high precision energy measurement soc chip. The communications capability and reliability of its communication module has reached the level of widespread practical application. It is a modern advanced meter designed and manufactured according to the actual energy consumption conditions with the application of digital sampling technology and smt technology.
Its performance indicators are in line with iec 62053-21: 2003 electricity metering equipment (a.C.) - particular requirements - part 21: static meters for active energy (classes 1 and 2), iec 62053-23: 2003 electricity metering equipment (a.C.) - particular requirements - part 23: static meters for reactive energy (classes 2 and 3) and iec 62052-11: 2003 electricity metering equipment (a.C.)general requires, tests and test conditions - part 11: metering equipment and other standards. The technical requirements of the smart meter can be made to measure the functional requirements; meanwhile, its telecommunication adopts a dedicated data encryption chip to ensure the security of quantity of electricity, tariff and other information
The main functions and features :
Meter circuit design and selection of the components are according as the tolerance of greater choice of environment, so we can guarantee long-term stability of a piece of work. Basically error will not affected by the frequency, temperature, high harmonics, and the installation of location is arbitrary. After sealing unit manufactured without adjustment, greatly reduced the power sectorf+s workload of testing and calibration, meter - button box with pulse interface light coupler facilitate error testing. Detection the constant of pulse output / kw.H to find weather it is the same as constant table marked on nameplate meter, meter also provides low-frequency pulse acquisition (opts). When the one phase of three-phase three-line network is broken, three-phase four-wire network with a two-phase power outages, the watt-hour meter still normal, and display the lost pressure. Power meter in the factory before carefully debugging and test the installation of qualified lead seals. Energy applies to an ambient temperature of -25 fp c to 70 fp c and relative humidity over 85% of the region.
