DL series Chengdu how to sell card meter? Chengdu card meter of how to sell? With automatic charge for water feature, users will be handed over water management, water management will purchase the IC card, the user IC card information input meter, water meter that automatically open the valve in the process of water users, water the microcomputer automatically subtract the amount of water, the amount of water used during the purchase of an alarm, the meter automatically close the valve without water. At this point the user to open the card close to the sensing area to continue water valve when the remaining water runs out, the meter automatically close the valve without water, the user must re-open the valve can only supply enough water again. Chengdu card meter of how to sell? The unique characteristics ★ non-contact (Chengdu how to sell the card meter?) Technology: the use of non-contact IC card technology, the meter wall using the wireless transmission of data, all electronic circuit contacts and electrodes sealed, no exposed electrode can be immersed in water to work properly, completely solve the water, moisture problems; Huiyi is the first company to install water meters within 1.8 meters of recharge wells manufacturers, their menu items to Chengdu safe drinking water in rural areas of Hebei City renovation project , four successive governments have chosen tender Hebei Huiyi IC card water meter, the total amount of the project has reached 40,000; ★ electric valve technology: the most modern technology for electric ball valves, reliable, low compression; ★ fully sealed design: All lines all with silicone seal, no exposed electrode; ★ anti-attack, magnetic attack techniques: When making a strong external electric and magnetic attacks, the meter will automatically close the valve and instructions; burglar ★ efficient use of film: In real life There are many users to steal water meter split by way of private, for the development of a practical and efficient heat shrinkable film that can be used with a hair dryer or boiling water poured over to shrink to complete the packaging, this film can not only watch but also tamper with rust, waterproof, moisture-proof protective effect of gas and aesthetic effect; ★ micro, micro memory technology: highly integrated, highly reliable. Multifunctional management unit and versatile non-contact IC card write card machine for DY series Chengdu Huiyi brand card meter of how to sell? Management, networking and computer use, the appearance of small fine. Write a card with a computer using a common USB interface to transfer data, simple and easy to apply. Non-contact IC card via radio waves, using Manchester coding reader card information, fully sealed, non-contact, waterproof, moisture-proof, anti-bending damage, anti-wear. Passing the sensing area can surface in any direction prepaid, each non-contact IC card has a unique serial number, and extremely difficult to crack the copy, is the trend in the future development of the IC card. China has issued a "second" is the use of radio frequency IC card technology. IC card prepaid water meter is the use of existing microelectronics technology, now sensing technology, IC card prepaid water metering technology and new water meter data transfer and settlement transactions. In addition to its water consumption can be recorded and electronic displays, but also can follow the conventions of the water is controlled automatically, and automatically calculate the price ladder of water tariff, while the data can be stored in water features. Due to its data transfer and transaction settlement through the IC card, and change can be achieved by the staff on-site meter reading fees to users themselves to the payment of business. The basic structural principle IC card water meter water meter and the general appearance was similar appearance, the installation process is basically the same. IC card meter is very simple to use, from a user's perspective, when the IC card chip on the meter inserted inside it. IC card water meter work process in general as follows: containing the amount of water meter IC card into the IC card reader, after the computer module identifies and download amount, the valve is opened, the user can normal water. When a user of water, the water collecting means for collecting water started and converted into electrical signals supplied to the microcomputer desired measurement module and displayed on the LCD display module. When the amount of water users down to a certain value, the microprocessor module audible alarm, prompting the user should go to the payment card to purchase water. If more than the amount of water, and then the computer module electrically controlled valve will automatically shut down, cutting off the water supply. Until the user inserts the IC card has been re-pay the valve begins to open water. Chengdu card meter of how to sell? With automatic charge for water feature, users will be handed over water management, water management will purchase the IC card, the user IC card information input meter, water meter that automatically open the valve in the process of water users, water the microcomputer automatically subtract the amount of water, the amount of water used during the purchase of an alarm, the meter automatically close the valve without water. At this point the user to open the card close to the sensing area to continue water valve when the remaining water runs out, the meter automatically close the valve without water, you need to re-purchase the water supply can only open the valve again. IC card can record the operation table, under the management of the management software or the total water table, the total purchase amount of water, the switch valve status information management. Chengdu card meter of how to sell? Can improve management efficiency, prevent arrears, to avoid door meter reading, to achieve water conservation.
