Smart meter uses advanced microcomputer control technology, IC card information carrier, using liquid seal wet and battery replacement technology, reliably achieve data acquisition, processing, display, storage and prepaid control. With low power consumption, strong anti-interference, high reliability, ease of installation, and change the original "first water, after the payment," as "the first payment after the water" to avoid the home stopwatch fees to users the inconvenience and improve the water supply industry and modern management level of property services. Smart meter, IC card smart meter, smart meter prepaid details: the smart meter fully sealed design: electronic circuit devices all epoxy seal ring, wear-resistant gold-plated contacts on nickel base card reader, moisture, water good performance of the United States TI MSP430 ultra-low power microcontroller, the circuit uses zero-power technology, the included battery life greatly improved, to ensure the use of more than 8 years of valve automatically sewage, blockades, rust-proof technology: automatic switching valve timing convenient replacement property under seal without destroying the whole table when the battery anti-foreign, magnetic attack techniques: the effective use of the pipeline pressure caused by the instantaneous momentum water discharge valve to avoid automatic valve fouling, rust and other phenomena independent of the battery compartment design : When the outside strong electric and magnetic attacks, the meter will automatically close the valve remaining water alarm function: When the table data to subtract the remaining water, prompting the user to automatically close the valve, so as not to affect users of water due to lack of water data transfer function: When You can use the card to transfer water meter project appear pardon barrier fault table data to the new table, which does not affect the user achieve the purpose of water to support normal water, electricity, heating card design, a user can manage four meter card, for a family Users can be described as multi-table is very convenient service commitment: The company within the product of two years of free maintenance and lifetime maintenance. 24 hours to reach the province, the province 48 hours to reach the service location.
