Prepayment meter features:
(1) It does not require manual meter reading and is conducive to modern management. With the implementation of “one household, one watch”, the number of electricity meters managed by power supply companies has increased dramatically. The installation of prepaid energy meters is a best choice for power supply companies to strengthen modern management and improve service levels. The use of pre-paid watt-hour meters also avoids the inconvenience caused by manual meter reading and door-to-door charges, and historical power purchase data can be saved to facilitate customer inquiries.
(2) fully reflects the water's commodity attributes. The pre-paid Water Meter follows the principle of commodity exchange, implements the purchase of water before use, completely reforms the traditional water fee collection mode, and fully embodies the hydraulic product attributes. Customers can purchase water and water in a planned manner according to their own actual needs, without delay due to arrears and unnecessary expenses.
(3) Solved the problem of difficulty in charging. It can well solve the problem of fees for scattered resident customers, temporary water customers, and frequently owed customers.

The basic parameters of the IC card prepaid water meter IC card prepaid water meter is based on advanced microcomputer control technology as the core, a smart card for information transmission media and constitutes a high-tech electromechanical integration smart meter, with the dual functions of mechanical counting and electronic counting, Mainly consists of smart card readers, low-power microcomputers, unique innovative motor valves, flow collection and corresponding circuits. While maintaining the characteristics of traditional mechanical water meters, it also has an intuitive electronic display. With the advantages of advanced design, high technical content, complete functions, accurate measurement, reliable performance, small size, intuitive display, exquisite appearance, convenient installation and convenient use, it is applicable to the measurement and charging of urban residents' tap water, avoiding stealing water and leaking water. The occurrence of water incidents has achieved the purpose of water conservation and scientific management through electronic billing and at the same time changed the traditional urban water supply management method, changing the “first water use, and later payment” as “pay first, then use water” to increase. The modern management level of the water supply industry also facilitates the use of users and avoids the inconvenience caused by meter-check charges to users.

Features:
◎Using dedicated imported microprocessor (MSP430 series produced by American TI company), ultra-low-power design ◎One-card-one-card function: Newly released user card is inserted into the new table, the table will automatically identify and save the unique code in the card. The code will be automatically recognized the next time the card is inserted, ie the watch automatically matches the card to prevent illegal use of the card. ◎The large-screen LCD is always displayed: Water data, valve status, battery status at a glance ◎ Low-voltage detection: When the battery voltage is lower At 3.8V, the motor valve will be closed and "undervoltage" and "off valve" will be displayed. The new battery must be installed before it can be used again. ◎The amount of water is insufficient. Note: When the amount of water remaining in the watch is less than 2.0m3, the valve will be closed automatically, prompting the user to purchase water. After the card is inserted, the valve can be opened, and the remaining amount of water can be used until it is 0. Off Valve ◎ Anti-counterfeiting function: When the card is inserted backwards or not inserted into the system card, “Card Error” will be displayed.
◎ Dedicated Engineering Card: Convenient maintenance ◎ Magnetic protection function: When a strong magnetic field approaches, the meter will display “Alarm” and close the valve. ◎ One-piece design: Compact structure, beautiful appearance ◎ Retain mechanical character wheel display: The whole watch has mechanical and electronic dual display function ◎ using four batteries: easy for users to replace ◎ intelligent month self-test function: to ensure reliable operation <br> <br> smart meter (intelligent cold water, hot water, the water meter) classification in a variety of interference:
Divided by the media temperature can be divided into intelligent cold water meter, smart hot water meter, cold water meter: medium lower limit temperature is 0 °C, the maximum temperature of 30 °C water meter.
