 Chongqing, a large caliber water meter ☆: 
 The control CPU of my company R & D and production of large diameter water meter, the RF card as the media, in the form of an induction of a variety of information entered into the large diameter water meter in Chongqing, Chongqing large diameter water meter of water 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) Chongqing large diameter water meter will automatically its electric valve Close The user simply used to purchase water into the large diameter water meter in Chongqing write card sensing area to sense the electric valves in the large diameter water meter within the Chongqing re-open the remaining water (ie, Chongqing, large caliber water less than 5m3 to the exhaustion of this period, a large caliber water in Chongqing to remind users to purchase water) five times without water way. If, to the exhaustion of the water remaining in the Chongqing large caliber water users do not purchase water and write Chongqing caliber water meter, electric valve will close until the user to purchase water and write large caliber water in Chongqing so far. In order to achieve the first to buy the water, the purpose of water ". 
 ? When Chongqing caliber water exhausted in the remaining water and electric valve is closed, for some reason (such as electric valve internal leak, etc.) water meter by the large diameter of Chongqing, Chongqing, large-diameter water meter will continue to be measured, the count of the number of negative values ??when the user to re-purchase of water and write large caliber water in Chongqing, Chongqing caliber water will first deduct the negative values ??(ie, the first overdevelopment of water), water newly written enough deductible super negative values ??of the water, the large caliber water in Chongqing electric valve does not open and continue to be closed until the remaining water in the large caliber water in Chongqing 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 purchase water card to (sensing area) induction, you can own the electric valve to open and Chongqing large diameter 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 of large caliber water in Chongqing attack, but also limit that it can not indefinitely human attack behavior of large diameter water meter in Chongqing. The Company produced multi-presented two of the company's trademark and warnings tamper shrink film than other Chongqing caliber water each installation, its pre-set into the receiver on, the Chongqing-caliber water meter installed and leak testing after passing tamper shrink film set in the large-diameter water meters in Chongqing to take over the nut, and then use a hair dryer (1600w high heat hair dryer) at the shrink film at the blow tamper 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. This product in addition to the above characteristics, the following characteristics: (a) non-contact (RF card) information carriers, large diameter wear, fast transmission of information, confidentiality and anti-attack performance, high reliability; (b) the use of LCD LCD the total quantities of water purchased, and the remaining water and all kinds of information; c 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) electronic 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 the use of large diameter and LCD dual display, so as not to affect the Chongqing large diameter water meter accuracy test and calibration; h. overall closed-shell design, anti-attack, waterproof, moisture, anti-smoke, anti-knocking; i water sales to read and write card machine 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 GB GB/T778-1996 cold water Chongqing large diameter water meter and the line marked CJ/T133-2006 Chongqing large caliber water standards.

 ? A, Hui Yi brand Chongqing, a large diameter water meter Introduction to Chongqing, a large caliber water meter is defective development in recent years, large-diameter water meter for ordinary Chongqing small flows (less than 8L / H) measured up. Ordinary Chongqing large caliber water 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 less than the starting flow of this drip Chongqing large diameter water meter is not metering for large diameter water pipe-line, so that the water supply enterprises have suffered losses. To solve this problem, Beijing Hui Yi has developed a differential pressure integral anti-drip Chongqing large diameter water meter, simply does not change the meter movement in advance of the large diameter of Chongqing, the drop out of the water in drip first accumulate when the save suddenly promoted a certain amount of Chongqing, a large caliber water impeller rotation to achieve the purpose of drip measurement 
 ? Second, the product uses and characteristics: the total amount of this series Chongqing caliber water flowing through the large diameter pipe drinking water for high sensitivity, 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 ordinary Chongqing large diameter water 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-class anti-drip Chongqing large diameter water meter; 4, in the 0.5L / h to 14L / h under the micro-flow state for the intermittent measurement (as if the displacement of Chongqing large diameter 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
