 ? My company R & D and production of Nanjing magnetic water meter, RF card as the media, will be in the form of an induction of a variety of information input to the the Nanjing magnetic meter control CPU, Nanjing magnetic meter of water purchased by the user automatically open the valve the water supply, 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) the Nanjing magnetic meter automatically inside the electric valve shut down at this time Users only need to purchase water used to write into the the Nanjing magnetic meter card "induction zone" to sense the electric valve Nanjing magnetic meter re-open (ie, the remaining water in the Nanjing magnetic meter is less than 5m3 to exhaustion During this time, the Nanjing magnetic meter five times without water way to remind users to purchase water). To the exhaustion of the remaining water in the Nanjing magnetic meter, if you do not purchase the water and write the the Nanjing magnetic meter motorized valve will close until the user to purchase water and write Nanjing magnetic 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 magnetic meter is exhausted in the remaining water and electric valve is closed, for some reason (such as electric valve internal leakage etc.) as well as water flowing through the the Nanjing magnetic water meter, Nanjing magnetic meter will continue to be measured, the number counted as a negative value, when the users to purchase water and write Nanjing magnetic meter, Nanjing magnetic 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 magnetic meter electric valve does not open and continue to be closed until the remaining water in the Nanjing magnetic 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 be induced to purchase water card to (sensing area), you can own the electric valve to open and Nanjing magnetic 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 the Nanjing magnetic water meter has been the ability to attack, but also to limit the behavior that it can not indefinitely Nanjing magnetic meter man-made attack. The Company produced more than other Nanjing magnetic meter each presented two of the company's trademark and warnings tamper shrink film, installation, pre-set into to take over, Nanjing magnetic water meter installation completed and leak testing and qualified, tamper shrink film magnetic meter, Nanjing took over the nut, then use the hair dryer (1600w high heat hair dryer) at the tamper shrink film at the blow or above 90 ℃ hot water 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 (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 do not affect the the Nanjing magnetic meter accuracy verification and validation; 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, 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 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 the the GB GB/T778-1996 cold water Nanjing magnetic water meter and the line marked CJ/T133-2006 "Nanjing magnetic water meter standard. Magnetic water meter, a, Hui Yi brand Nanjing magnetic meter Nanjing in recent years aimed at Nanjing magnetic meter in the micro flow (less than 8L / H) measured defect developed. Ordinary the Nanjing magnetic water meter due to the 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, People can use way less than the starting flow of this drip the Nanjing magnetic meter is not measured to obtain the water of the water pipe-line, so that the water supply enterprises suffered losses. To solve this problem, Nanjing Hui Yi has developed a pressure differential integral anti-drip the Nanjing magnetic water meter, it simply does not change the the Nanjing magnetic meter movement in advance, drop out of the water in drip first accumulate, save to a certain amount of suddenly promote Nanjing magnetic meter rotating impeller to achieve the purpose of drip measurement 
 ? Second, the product uses and characteristics: This series of Nanjing magnetic water meter 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; 16 times more than ordinary Nanjing magnetic meter; 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 that 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 C-level anti-drip the Nanjing magnetic water meter; 4, 0.5L / h to 14L / h under the micro-flow state for the intermittent measurement (like displacement Nanjing magnetic meter does), and 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
