 R & D and production company Chongqing mechanical water meter, RF card as media will be all kinds of information in the form of an induction input to the control CPU of the mechanical water meters in Chongqing, the Chongqing Machinery meter of water purchased by the user automatically open the valve the water supply, remaining water to less than 5m3 (containing 5m3) but have not yet exhausted, and every integer (for example, the remaining water to 4m3, 3m3, 2m3, 1m3) Chongqing Machinery meter will automatically power within its valve closed, the user only with the purchase of water into the the Chongqing mechanical water meter to write card sensing area to sense can re-open the electric valve in the mechanical meter Chongqing (Chongqing Machinery meter remaining water is less than 5m3 to the exhaustion of this period of time, Chongqing Machinery meter five times without water way to remind users to purchase water). To the exhaustion of the remaining water in the Chongqing mechanical water meter, if the users do not purchase water and write Chongqing Machinery meter motorized valve will close until the user to purchase water and write inside until the Chongqing mechanical meter. In order to achieve the first to buy the water, the purpose of water ". 
 ? After Chongqing mechanical meter exhausted in the remaining water and electric valve is closed, for some reason (such as electric valve internal leakage) flow through the meter Chongqing Machinery, Chongqing mechanical water meters will continue to be measured, the number counted as negative values ??when the user re-purchase of water and write the Chongqing Machinery meter, Chongqing mechanical 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 Chongqing Machinery meter electric valve does not open the continued closure of the remaining water in the mechanical meter 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 be induced to purchase water card to (sensing area), you can own the electric valve open and the normal work of the meter of Chongqing Machinery. 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 Chongqing mechanical water meter has been the ability to attack, but also to limit the behavior so that it can not indefinitely Chongqing Machinery meter man-made attack. Produced by our company, donated more than other Chongqing mechanical water meters for each two of the company's trademark and warnings tamper shrink film, installation, pre-set into to take over, Chongqing mechanical water meter installation completed and leak testing and qualified, the anti-demolition of heat shrinkable film set in Chongqing Machinery meter take over the nut, 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 meter accuracy test and calibration of the Chongqing Machinery; 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 cold water Chongqing Machinery meter and line marked CJ/T133-2006 Chongqing Machinery meter standard.

 ? A Huiyi brand Chongqing Machinery meter Introduction to Chongqing mechanical water meters in recent years for ordinary the Chongqing mechanical water meter in the tiny flow (less than 8L / H) the development of non-quantified defect. Ordinary the Chongqing mechanical water meters due to the 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 Chongqing mechanical water meter is not metering to obtain water of mechanical pipe-line, so that the water supply enterprises suffered losses. To solve this problem, Beijing Hui Yi has developed a differential pressure integral anti drip Chongqing Machinery meter, it simply does not change the the Chongqing mechanical meter movement in advance, in drip drop out of the water first accumulate, save to a certain amount of suddenly promote the Chongqing mechanical meter impeller rotation drip measurement purposes 
 ? Second, the product uses and characteristics: This series of Chongqing mechanical water meters for the total amount of high sensitivity through mechanical 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; more than 16 times the ordinary Chongqing Machinery 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 anti-drip institutions will not impurities in the water is clogged or stuck; 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 the anti-submarine The dynamic performance is far superior to the jet and C-level anti-drip the Chongqing mechanical water meter; 4, 0.5L / h to 14L / h under the micro-flow state for the intermittent measurement (like displacement Chongqing Machinery meter), and this 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, 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
