 R & D production the Qiongshan card meter, RF card as the media, all kinds of information in the form of an induction entered into the the Qiongshan card meter control CPU, Qiongshan card 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) the Qiongshan card meter automatically within electric valve is closed, the Users only need to purchase water used to write into the the Qiongshan card meter card "induction zone" to sense what the Qiongshan card water meter, electric valve to re-open (ie Qiongshan card water meter within the remaining water is less than 5m3 to exhaustion this time, the the Qiongshan card water meter to remind users to purchase water) five times without water way. To the the Qiongshan card water meter within the remaining water is exhausted, if the users do not purchase water and writes Qiongshan card water meter, electric valve will close until the user to purchase water and write Qiongshan card water meter inside so far. In order to achieve the first to buy the water, the purpose of water ". 
 ? When the The Qiongshan card water meter and electric valve is closed in the remaining water exhausted for some reason (such as electric valve internal leakage, etc.) flow through the Qiongshan card water meter the Qiongshan card meter will proceed measurement, the number counted as a negative value, when the user re-purchase of water and write Qiongshan card meter, Qiongshan card meter will first deduct the negative values ??(ie, the first also super water), if the new write The water is not enough ultra-deductible to the negative value of the water, Qiongshan card water meter electric valve to open and continue to be closed up the Qiongshan card water meter within the remaining water 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 Qiongshan card water meter electric valve to open and 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 do are free to lift the the Qiongshan card water meter has been the ability to attack, but also to limit the behavior so that it can not indefinitely Qiongshan card water meter man-made attack. Produced by our company, multi-presented two of the company's trademark and warnings tamper shrink film than any other the Qiongshan card meter for each installation, its pre-set into the take over on, Qiongshan card meter installed and leak testing and qualified, tamper shrink film set in the of Qiongshan card meter take over the nut, and then use the hair dryer (1600w high heat hair dryer) at the shrink film at the blow tamper or Pour hot water above 90 ℃ alignment tamper shrink film, shrink film, shrink to take over the shape of the nut to tight coupling. 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 , which does not affect the the Qiongshan card water meter accuracy test and calibration; h. overall closed-shell design, anti-attack, waterproof, moisture, fumes, anti-knocking; i the sale of water to read and write card machine can separate use, 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 GB/T778-1996 "cold water the Qiongshan card water meter and the line marked CJ/T133-2006 the Qiongshan card meter" standard.

 ? A, Hui Yi brand the Qiongshan card meter Introduction Qiongshan card meter for ordinary Qiongshan card meter in recent years in the minor flow (less than 8L / H) is not measured defect developed. Ordinary Qiongshan card water meter due to movement of the rotating parts and count the gear inertia, and therefore 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, to the small flow can not be measurement, people can be less than the starting flow of this drip way the Qiongshan card water 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 the Qiongshan card meter, simply does not change under the the Qiongshan card meter movement in advance, in drip drops out of the water first accumulated up when save to a certain amount of a sudden promote Qiongshan card meter impeller rotation reach dripping measurement purposes 
 ? Second, the product uses and characteristics: This series of Qiongshan card 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 is less than 0.5 L / h; more than 16 times the ordinary Qiongshan 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 that the anti-drip institutions will not be blocked or stuck in the impurities in the water; 3, anti-slip performance: ordinary movement velocity, not idling, soft diaphragm can offset part of the water hammer pressure, coupled with anti-drip institutions closed, so its anti-creep performance is far superior to the jet and C-level anti-drip the Qiongshan card meter; 4, in the 0.5L / h to 14L / h under the micro-flow state for the intermittent measurement (like displacement Qiongshan card water meter), and micro-flow range measurement error is small; 5, of the authority of experts convened by the Ministry of Construction and Water Association to identify 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
