Detailed Product Description: | ? ☆ Chongqing pre-paid water meters № Chongqing pre-paid water meters offer № Chongqing prepaid water meter price ★ ? ? Chongqing pre-paid water meters ☆: R & D and production of company the Chongqing pre-paid water meters, RF card as a form of media, a variety of information using sensing input to Chongqing, pre-paid water meters control CPU, Chongqing, pre-paid water meters to the water purchased by the user to automatically open the valve water supply, when the remaining water to less than 5m3 (with 5m3) but have not yet exhausted, and every integer (for example, the remaining water to 4m3, 3m3, 2m3, 1m3), Chongqing, pre-paid water meters will automatically inside the electric valve is closed Users only need to purchase water used to put Chongqing pre-paid meter card write "sensing zone" to sense the Chongqing pre-paid water meters within the electric valve to re-open (ie, Chongqing, pre-paid water meters within the remaining water less than 5m3 to exhaustion during this time, Chongqing, pre-paid water meters to 5 times without water way to remind users to purchase water). If to Chongqing prepaid the remaining water inside the water meter is exhausted, users do not purchase the water and write Chongqing prepaid water meter, electric valve will be closed until the user to purchase water and write the Chongqing pre-paid water meters within. In order to achieve the first to buy the water, the purpose of water ". ? When exhausted Chongqing pre-paid water meters in the remaining water and electric valve is closed, for some reason (such as electric valve internal leak, etc.) water pre-paid water meters by the Chongqing, Chongqing, pre-paid water meters will continue to be measured, the count of the number of negative values ??when the user re-purchase of water and write Chongqing pre-paid water meters, Chongqing pre-paid water meters will first deduct the negative values ??(ie, the first also super water), if the amount of water newly written enough deductible super negative values ??of the water, Chongqing, pre-paid water meters within the electric valve does not open and continue to be closed until the Chongqing pre-paid water meters within the remaining water is positive. 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, pre-paid water meters. 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 Chongqing pre-paid water meters have been attacks, and limit the behavior so that it can not indefinitely Chongqing prepaid meter man-made attack. Produced by our company than other Chongqing pre-paid water meters for each multi-presented two of the company's trademark and warnings tamper shrink film, installation, pre-set into to take over Chongqing prepaid water meter installed and leak testing after passing tamper shrink film pre-paid water meters in Chongqing take over the 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, prepaid 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. measurement display pre-paid and LCD dual display, so as not to affect the Chongqing pre-paid 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 pre-paid water meters and line marked CJ/T133-2006 Chongqing pre-paid water meters "standard.

A, Hui Yi brand Chongqing prepaid meter Introduction to Chongqing pre-paid water meters in recent years, pre-paid water meters for ordinary Chongqing 8L / H) measured in the small flow rate (less than defects developed. Ordinary the Chongqing pre-paid 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 at can be used less than the starting flow of this drip pre-paid water meters not measured access to pre-pay to pipe the water online in Chongqing, so that the water supply enterprises suffered losses. To solve this problem, Beijing Hui Yi has developed a pressure differential integral anti-drip pre-paid water meters in Chongqing, simply does not change the Chongqing pre-paid water meter movement in advance, the drop out of the water in drip first accumulate when the save a certain amount of a sudden promote Chongqing prepaid water meter impeller rotation to achieve the purpose of drip measurement ? Two, the product uses and characteristics: Chongqing, pre-paid water meters for high sensitivity to flow through the pre-paid the total amount of drinking water pipe, its main features are as follows: 1, the smaller the initial flow rate, the initial flow rate of less than 0.5L / h; is ordinary Chongqing pre-paid water meters, 16 times or more; 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 Chongqing pre-paid water meters; 4, 0.5L / h to 14L / h under the micro-flow state for the intermittent measurement (like displacement Chongqing pre-paid water meters ), 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 ? Beijing Hui Yi Chongqing, all members of the pre-paid water meter Co., Ltd. sincerely welcome you to Beijing Hui Yi Chongqing pre-paid water meter factory guidance inspected! ? |
