 ? The Nanjing card company R & D and production meter, is swipe the card as a media, a variety of information using the sensor in the form of input to Nanjing credit card water meter control CPU, Nanjing card meter of water purchased by the user automatically open the water supply valve, When the remaining water to less than 5m3 (including 5m3) but have not yet exhausted, every integer (for example, the remaining water to 4m3, 3m3, 2m3, 1m3) Nanjing card meter will automatically be electric valve in its shut down, this time Users only need to purchase water into the Nanjing card water meter card to write the sensing area to sense the electric valve in Nanjing, credit card water meter re-open (ie, the remaining water in the Nanjing card meter is less than 5m3 to exhaustion Nanjing card meter five times without water this time, to remind the user to purchase water). To Nanjing card the remaining amount of water in the meter exhausted, the user not to purchase water and write Nanjing card water meter within the motorized valve will close until the user to purchase water and write Nanjing credit card meter so far. In order to achieve the first to buy the water, the purpose of water ".

 ? Official website: http://tangcuiqin.jdzj.com http://www.qinaiping.icoc.cn/ Nanjing card meter exhausted in the remaining water and electric valve is closed, for some reason (such as electric valve internal leakage , etc.) as well as water Nanjing card meter, Nanjing card meter will continue to be measured, the number counted as a negative value when the user re-purchase of water and write Nanjing card meter, Nanjing card water meter will first deduct the negative values ??(ie The first also super water), if water is not enough deductible newly written negative values ??of the super water Nanjing card meter electric valve does not open and continue to be closed until the remaining water in the Nanjing card water meter is positive so far. When the Company suffered such as magnetic and other external attacks, within one minute inside the electric valve shut down. At this point, the user can purchase water card to (sensing area) induction can own electric valve open and the Nanjing card meter. However, if such an attack accumulated more than 10 times more users to purchase water card will no longer be able to open its electric valve (in case the user man-made attack), high a check card (water management The department only holds) to the electric valve is opened, the same time attack record clear (after the user configuration of the water cards but also because of the attack and then open the 10th). Enabling it to achieve the ability to self-lifting Nanjing card meter of the assault, but also limit the behavior so that it can not be unlimited in Nanjing card meter artificial attack. Produced by our company than any other Nanjing credit card more than a meter each presented two of the company's trademark and warnings tamper shrink film, installation, and its pre-set into the take over on to the Nanjing card meter installed completed and leak testing and qualified, tamper shrink film card meter in Nanjing took over the nut, and then use a hair dryer (1600w high heat hair dryer) at the tamper shrink film at the blowing or use hot water above 90 ℃ alignment tamper Pour of shrink film, shrink film, shrink to take over the shape of the nut to the hoop tight. To split the table must be tamper destruction of heat shrinkable film, thus preventing the artificially split the table for the purpose of stealing water. In addition to the above characteristics, the product, the following characteristics: (a) non-contact (swipe card) information carrier, no mechanical wear, fast transmission of information, confidentiality and anti-attack performance, high reliability; (b) with LCD display the total quantities of water purchased, and the remaining water and all kinds of information; when the remaining water is zero or alarm value, automatically close the valve without water; d the entire system is usually in the off state, static power consumption is zero; (e) electric control valve patented electric valve to completely overcome the electromagnetic valve interference and shutdown lax defects; f unique anti-theft of water, tamper table, anti-reversal device; g metering display by mechanical and LCD Dual Display does not affect the the Nanjing credit card verification and calibration of the meter accuracy; h, the overall closed-shell design, anti-attack, waterproof, moisture, fumes, anti-knocking; i read and write cards of the sale of water management unit may be used alone, can also use the computer network. The company produces technical parameters are as follows: Working power supply: two 3.6V lithium battery, the working life of 8-10 years; (b) usually operating current: 0A;. C. Instantaneous operating current :1-5MA; d. Swipe card Life time:> 100 000; (e) Working pressure: 1MPa below normal work; (f) the operating temperature range (temperature) :0.3-40 ° C; g. the whole life of 8-10 years. This product complies with the GB GB/T778-1996 cold water Nanjing card meter "and the line the standard CJ/T133-2006 Nanjing card water meter standards. A, Hui Yi brand the Nanjing card meter Nanjing card water meter is developed in recent years aimed at Nanjing card meter 8L / H) measurement of small flows (less than defects. Ordinary the Nanjing card water meter due to the movement of the rotating parts and count the gear inertia, so in the measurement process, if the water flow is small to a certain degree will not be able to promote the movement of the impeller and counter gear, thus the micro flow can not be measured, people can be way less than the starting flow of this drip the Nanjing card water meter not measured to obtain the water pipe line of water, so that the water supply enterprises have suffered losses. To solve this problem, Nanjing Hui Yi has developed a differential pressure integral anti-drip the Nanjing card meter, simply does not change the Nanjing credit card ahead of the meter movement in drip drops out of the water first accumulated up when save to a certain amount of suddenly promote Nanjing card meter impeller rotation reach dripping measurement purposes 
 ? Usage and Features: This series the Nanjing card water meter used for the total amount of the high sensitivity of flows through a water pipe drinking water, its main features are as follows: 1, the smaller the initial flow rate, the initial flow rate of less than 0.5L / h; ordinary Nanjing card meter more than 16 times; adaptability to water quality: due to the drainage channel between the anti-drip institutions and outlet distance of 4mm, by particles below 4mm, so that the anti-drip institutions will not be impurities in the water is clogged or stuck; 3, anti-slip performance: ordinary movement is the flow rate, not idling, soft diaphragm can offset part of the water hammer pressure, coupled with anti-drip closure of the institution, so the anti-creep performance far superior to the jet and the C-class anti-drip Nanjing card water meter; 4, 0.5L / h to 14L / h under the micro-flow state for the intermittent measurement (like displacement Nanjing card meter), and this micro- the flow range of measurement error; authoritative experts, convened by the Ministry of Construction and the China Water Association, our identification of the products and technologies, and its technology has reached the leading domestic level. Can guarantee the normal work for more than 10 years of anti-drip institutions. Conditions of use: the work of the water temperature does not exceed 40 ℃, working pressure is not greater than 1Mpa. Four, show error: less than the minimum flow (Qmin) of the trace does not count; from including minimum flow (Qmin) to but excluding the boundaries of flow (Qt) of low district: ± 5%; from including the boundaries of flow (the Qt) to include overload In the upper zone of the flow (Qmax): ± 2%. Pressure loss: △ ≤ 0.1Mpa
