 ? R & D and production company, Nanjing ic card meter, based on RF card as the media will be all kinds of information in the form of an induction input to the control CPU of Nanjing ic card meter, Nanjing ic 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, and every integer (for example, the remaining water to 4m3, 3m3, 2m3, 1m3) Nanjing ic card meter will automatically be within the electric valve Close, Users only need to purchase water into the Nanjing ic card meter card write "sensing area to sense the electric Nanjing ic card meter valve re-open (ie, the Nanjing ic card meter remaining water is less than 5m3 to exhaustion during this time, Nanjing ic card meter five times without water way to remind the user to purchase the water). To the exhaustion of the water remaining in the Nanjing ic card meter, users do not purchase water and write Nanjing ic card water meter, electric valve will close until new users to purchase water and write Nanjing ic card water meter within the date. 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 ic card meter and electric valve is closed in the remaining water exhausted for some reason (such as electric valve internal leakage) flow through the ic card meter when Nanjing, Nanjing ic card meter will continue to be measured, the number counted as a negative value when the users to purchase water and write Nanjing ic card meter, Nanjing ic card meter will first be deducted negative values ??(ie, the first also super water), if water is not enough deductible newly written negative values ??of the super water ic card meter within the Nanjing electric valve to open and continue to be closed until the Nanjing ic card meter The remaining water 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, you can own the electric valve to open and Nanjing ic card water meter work properly. 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 self-lifting of the ability to attack Nanjing ic card meter, and limit the behavior so that it can not be infinite ic card meter in Nanjing human attacks. Produced by our company, Nanjing ic card than other Nanjing ic card meter for each multi-presented two of the company's trademark and warnings tamper shrink film, installation, pre-set into to take over on water meter installed and leak testing after passing tamper shrink film take over the nuts in Nanjing, ic card meter, and then use a hair dryer (1600w high heat hair dryer) at the shrink film at the blow tamper or above 90 ℃ hot water alignment tamper Pour of shrink film, shrink film shrink while the nut take over the shape of 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 (RF 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 and thus does not affect the verification and validation of the Nanjing ic card meter accuracy; h. 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 , but also with computer networking. 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 work current: 0A; c instantaneous operating current :1-5MA; d. RF 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 the GB/T778-1996 cold water Nanjing ic card water meter and line marked CJ/T133-2006 Nanjing ic card meter standard. A, Hui Yi brand Nanjing ic card meter Introduction to Nanjing ic card meter in recent years, in the micro flow for ordinary Nanjing ic card meter (less than 8L / H) measured defects developed. Ordinary Nanjing ic card meter due to movement of the rotating parts and count the gear inertia, so in the measurement process if the water flow to a certain extent will not be able to promote the movement of the impeller and counter gear, thus the micro flow can not be measured at people can be using way less than the starting flow of this drip the Nanjing ic card water meter is not measured to obtain the water of the water pipe-line, so that the water supply enterprises have suffered losses. To solve this problem, Nanjing Hui Yi has developed a differential pressure integral anti-drip Nanjing ic card meter, it simply does not change the Nanjing ic card meter movement in advance, in drip drop out of the water first accumulate, when the save a certain amount of a sudden promote Nanjing ic card meter impeller rotation drip measurement purposes 
 ? Second, the product uses and characteristics: This series of Nanjing ic card meter for high-sensitivity total flows through the 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; more than 16 times the ordinary Nanjing ic card meter; 2, adaptability to water quality: due to the drainage channel between the anti-drip institutions and outlet distance of 4mm, so by particles below 4mm, so anti drip institutions do not will be clogged by impurities in the water or get stuck; 3, anti-slip performance: general movement velocity, 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 is far superior to the jet and C-class anti-drip Nanjing ic card meter; 4, in the 0.5L / h to 14L / h under the micro-flow state for intermittent measurement (like displacement Nanjing ic card meter the same) and micro-flow range measurement error is small; 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 domestic leading 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
