 The Qiongshan water meter ☆: 
 The control CPU of my company R & D and production of the Qiongshan water meter, the RF card as the media, in the form of an induction of a variety of information entered into the the Qiongshan water meter, water the Qiongshan water meter purchased by the user automatically open the valve water supply, when the surplus 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 water meter automatically the electric valve inside the Close Users only need to write into the the Qiongshan water meter card used to purchase water sensing area to sense what can be the Qiongshan water meter within the electric valve re-open the remaining water (Qiongshan water meter less than 5m3 to exhaustion this time, the the Qiongshan water meter five times without water way to remind the user to purchase the water). To the the Qiongshan the remaining amount of water within the water meter is exhausted, users do not purchase water and write it to the the Qiongshan water meter, electric valve will be closed until the user to purchase water and written to the the Qiongshan water meter within the date. In order to achieve the first to buy the water, the purpose of water ". 
 ? Qiongshan water meter is exhausted in the remaining water and electric valve is closed, for some reason (such as electric valve internal leak, etc.) by the Qiongshan water meter when there is water, the Qiongshan water meter will continue to be measured, the the number counted as a negative value when the users to purchase water and write Qiongshan water meter, Qiongshan water meter will first deduct the negative values ??(ie first overdevelopment of water), new write to the amount of water is enough deductible super negative values ??of the water, the the Qiongshan water meter within the electric valve does not open and continue to be closed until the the Qiongshan 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 the electric valve open and the Qiongshan 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 the Qiongshan water meter has been the ability to attack, but also to limit the behavior so that it can not be infinite on the the Qiongshan water meter man-made attack. Produced by our company, donated more than other the Qiongshan water meter for each within two of the company's trademark and warnings tamper shrink film, installation, on its pre-set into the receiver will Qiongshan water water meter installed and leak testing after passing tamper shrink film set to take over in the the Qiongshan water meter nut, and then use a hair dryer (1600w high heat hair dryer) at the tamper shrink film at blowing 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 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 water meter accuracy test and verification; h, the 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 GB/T778-1996 "cold water Qiongshan water meter" and line marked the CJ/T133-2006 the Qiongshan water meter standard.

 ? A, Hui Yi brand the Qiongshan water meter Introduction to the Qiongshan water meter is in recent years for ordinary the Qiongshan water meter in the tiny flow (less than 8L / H) the development of non-quantified defect. Ordinary Qiongshan 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 at people can be way less than the starting flow of this drip the the Qiongshan water meter is not metering 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 water meter, it simply does not change, the advance of the the Qiongshan water meter movement in drip drop out of the water first accumulate, when the save a certain amount of a sudden promote the Qiongshan water meter impeller rotation drip measurement purposes 
 ? Second, the product uses and characteristics: This series of The Qiongshan water meter 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; more than 16 times the general the Qiongshan water meter; 2, adaptability to water quality: due to the drainage channel between the anti-drip institutions and outlet distance of 4mm, so 4mm below the particle, so that the anti-drip institutions are 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-level anti-drip the Qiongshan water meter; 4, 0.5L / h to 14L / h under the micro-flow state for the intermittent measurement (as if volumetric the Qiongshan water meter) 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
