 ? ☆ Our R & D production in Lianyungang ic card meter ic card meter, based on RF card as media, a variety of information using the sensor in the form of input to the control CPU of the ic card meter, ic card water meter of water purchased by the user the water supply valve is automatically opened, when the remaining amount of 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) ic card meter will automatically within the electric valve closed, the user simply purchase water into the ic card meter card write "sensing area to sense the electric valve ic card meter re-open the remaining water (ie, ic card meter 5m3 to exhaustion during this time, ic card meter five times without water way to remind the user to purchase water). If to the exhaustion of the water remaining in the ic card meter, users do not share water and write ic card water meter, electric valve will be closed until the user to purchase water and write ic card meter. In order to achieve the first to buy the water, the purpose of water ". 
 ? Information, please contact Tang cocoa 18,701,502,378 QQ 1024492555 When 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, ic card water meter will continue to be measured, their number is counted as a negative value when the user re-purchase of water and write the ic card meter, ic card meter will first deduct the negative values ??(ie, the first also super water), if not enough water newly written deductible super negative values ??of the water, ic card water meter, electric valve does not open but remain closed until the ic card meter water remaining positive until. 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 electric valve is opened and ic card 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 ic card water meter has been the ability to attack, but also limit so that it can not be infinite human attack behavior of the ic card meter. The Company produced, than the other 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, ic card water meter installation completed and leak testing and qualified, tamper shrink film take over the nut on the ic card meter, 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 , which does not affect the verification and validation of the 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, 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 standards of GB GB/T778-1996 cold ic card meter and the line marked CJ/T133-2006 "ic card meter. Huiyi brand ic card meter Profile ic card meter is developed in recent years, the tiny flow for ordinary ic card meter (less than 8L / H) measured at defects. Ordinary ic card water 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, people can be less than the starting flow of this drip ic card water meter is not metering access to the water pipe line of water, so that the water supply enterprises suffered losses. To solve this problem, Beijing Hui Yi has developed a differential pressure integral anti-drip ic card meter, it simply does not change the ic card meter movement in advance, will drop out of the water in drip first accumulate, save to a certain amount of suddenly promote the ic card meter rotating impeller to achieve the purpose of drip measurement 
 ? Second, the product uses and characteristics: 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; 16 times more than ordinary ic card meter; 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 C-level anti-drip ic card water meter; 4, in the 0.5L / h to 14L / h under the micro-flow state for intermittent measurement (as if the volume of ic card meter does), 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
