Yunnan meter manufacturers / Purchasing Wholesale / card smart meter / smart IC card heat meter price HYNW Description: HYNW smart IC card prepaid series heat meter is Huiyi Industry and Trade Co., Ltd. developed independently, with completely independent intellectual property products It is the most advanced micro-power single-chip micro-processing technology, ultrasonic flow meter, temperature sensor, LCD, long-life battery technology combined with organic, integrated optimization model can be realized with my company's prepaid Fees water, electricity meters constitute a unified "integrated card" management system. Yunnan meter manufacturers / Purchasing Wholesale / card smart meter / price modular structure designed to achieve the data transmission data display, data storage, and pre-paid fees related features, especially when we form the core of high quality, it has consumption function is low, strong anti-jamming performance, reliability, good stability, easy installation and other characteristics. Yunnan magnetic meter manufacturers are the main features: ① prepaid function: water through the water purchase card sale, used automatically close the valve, to achieve the first purchase of water use; ② price ladder functions: water meter on monthly water consumption by setting the Ladder Price Break billing; also be easily configured as a single tariff; ③ hoarding limit function: When the amount of water balance and recharge, and greater than the set limit, you can not recharge transactions; ④ refund function: the user cancel the account management system can be returned to the table through the remaining amount, refund after renew; ⑤ a card table: a perfect encryption system, the table data can be maintained for ten years. Users can keep track of the cumulative amount of water meter, the remaining amount (the remaining amount) monthly water consumption, etc.; Anti-attack design, with black box function: magnetic interference measurement signal, automatically record exception information, close the valve; pre-warning function: According to need to set the alarm, overdraft of water, water to set the alarm or overdraft, the meter will automatically close the valve prompts the user to purchase water; KEB Function battery: battery meter can be realized around the outside to replace, cut replacement process is simple, so Batch Replace the battery is no longer a pipe in the water sector problems; prevent the battery from hibernation: the use of a combination of hardware and software to prevent battery dormant; dual display: a mechanical counter and LCD dual display; unique anti-crash circuit and the number of fault-tolerant design; Yunnan Card smart meter ability to adapt to the environment control system by valve system which gives the pressure loss much lower than other structures of the valve pressure drop, while the valve drive torque generated by the torque required for valve itself is more than 3 times, more than 300% insurance factor prevents scaling, long-term without too many impurities resulting uncontrolled consequences; signal acquisition using high quality double reed, alternating work, which is equivalent to the bistable mode, which can effectively prevent fibrillation, backwater measurement error brought, and can detect the external magnetic interference, to ensure the mechanical and electronic part of counting the same, if the external magnetic interference, two reed then simultaneously pull, start to close the valve control part program to prevent human Pirates of water.
