 Ding-an intelligent water meter ☆: 
 Our R & D fixed the smart meter, the RF card as media in the form of an induction of a variety of information input to the Ding-an intelligent water meter control CPU, the amount of water of Dingan smart meter purchased by the user automatically open the 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), Honour the smart meter will automatically power within its valve closed, the user just used to write into the of Dingan smart meter card to purchase water sensing area to sense the electric valve in the Ding-an intelligent water meter re-open (ie, the Ding-an intelligent water meter within the remaining water is less than 5m3 to the exhaustion of this period of time, be safe for the smart meter five times without water way to remind users to purchase water). If to the exhaustion of the remaining water in the Ding-an intelligent water meter, the user is not purchased water and written to the Ding-an intelligent water meter, electric valve will be closed until the user to purchase water and write inside until the Ding-an intelligent water meter. In order to achieve the first to buy the water, the purpose of water ". 
 ? When the Ding-an intelligent water meter is exhausted in the remaining water and electric valve is closed, for some reason (such as electric valve internal leakage, etc.) when the water flowing through the Ding-an intelligent water meter, the Ding-an intelligent water meter will continue to be measured, the number counted as negative values ??when the user re-purchase of water and write Dingan smart meter, the Ding-an intelligent meter will first be less negative values ??(ie, the first also super water), if water is not enough deductible newly written negative values ??of super-water An intelligent water meter within the electric valve is scheduled to not open, remain closed until the remaining water in the Ding-an intelligent 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 be induced to purchase water card to (sensing area), you can own the electric valve to open and Dingan smart meter working 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 Ding-an intelligent water meter has been the ability to attack, but also to limit the behavior so that it can not indefinitely set An intelligent meter man-made attack. The Company produced than other Dingan smart meter each multi-presented within two of the company's trademark and warnings tamper shrink film, installation, pre-set into the take over the Ding-an intelligent water meter installation completed and leak testing and qualified, tamper shrink film set in the of Dingan smart meter to take 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 (RF card) information carriers, electronic 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 measurement display using electronic and LCD Dual Display and thus does not affect the verification and validation of the Ding-an intelligent water 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, 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 GB GB/T778-1996 of cold water given the smart meter and the line marked CJ/T133-2006 Dingan smart meter standard.

 ? A the Huiyi brand the Dingan smart meter Introduction An intelligent water meter is developed in recent years aimed at Ding-an intelligent water meter in the small flow rate (less than 8L / H) measured defects. Ordinary fixed An intelligent water meter due to 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 use less than the starting flow of this drip Dingan the smart meter is not measured to obtain water tube online, so that the water supply enterprises suffered losses. To solve this problem, Beijing Hui Yi has developed a differential pressure integral anti-drip Ding-an intelligent meter, simply does not change the Ding-an intelligent water meter movement in advance, the drop out of the water in drip first accumulate, save to a certain amount of suddenly promote Dingan smart meter impeller rotation to achieve the purpose of drip measurement 
 ?, Product uses and characteristics of: Ding-an intelligent water meter for the total amount of the high sensitivity to flows through the tube 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 Dingan smart 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 Ding-an intelligent water meter; 4, An intelligent water meter in 0.5L / h to 14L / h under the micro-flow state for the intermittent measurement (like displacement given), 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
