Detailed Product Description: | ? ☆ Tianjin card water meter № Tianjin card meter offer № Tianjin card meter price ★ ? ? Tianjin card meter ☆: Our R & D production in Tianjin card meter based on RF card as the media will be all kinds of information in the form of an induction input within the control of CPU to the the Tianjin card water meter, the Tianjin card water meter the amount 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) when the Tianjin card meter automatically the electric valve inside the Close The users only need to purchase water use to write into the of Tianjin card meter card "induction zone" to the induction Tianjin card water meter electric valve can be re-open the remaining water (ie the Tianjin card meter less than 5m3 to the exhaustion of this period, Tianjin card meter five times without water way to remind users to purchase water). To the exhaustion of the remaining water in Tianjin card water meter, if you do not purchase the water and write their the Tianjin card meter motorized valve will close until the user to purchase water and write Tianjin card water meter within the date. In order to achieve the first to buy the water, the purpose of water ". ? When the Tianjin card water meter is exhausted in the remaining water and electric valve is closed, for some reason (such as electric valve internal leakage) flow through the Tianjin card meter, Tianjin card meter will continue to be measured, the the number counted as a negative value when the users to purchase water and write Tianjin card meter, Tianjin card meter will first deduct the negative values ??(ie, the first overdevelopment of water), water newly written enough deductible super negative values ??of the water, Tianjin card water meter electric valve does not open remain closed until the remaining amount of water in Tianjin card meter 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 Tianjin card 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 achieve self-lifting the Tianjin card water meter has been the ability to attack, but also to limit the behavior so that it can not be infinite on the the Tianjin card 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 Tianjin card meter for each installation, pre-set into to take over, Tianjin cassette water meter installed and leak testing after passing tamper shrink film set in Tianjin cassette receiver of the meter nut, and then use the 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. In addition to the above characteristics, the product, the following characteristics: (a) non-contact (RF card) information carrier, a table card wear, fast transmission of information, confidentiality and anti-attack performance, high reliability; b. using the LCD shows the total quantities of water purchased, 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, the static power consumption is zero; e-. electric control valve is a 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 a table multi-card and LCD dual display, so as not to affect the of Tianjin card water meter accuracy test and validation; h overall closed-shell design, anti-attack, waterproof, moisture-proof, anti-smoke, anti-knocking; i. water sales to read and write The card 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 Tianjin card water meter and the line marked CJ/T133-2006 the Tianjin card meter "standard.

Huiyi brand card water meter Tianjin About Tianjin card meter is defective development of recent years the ordinary Tianjin card meter in the small flows (less than 8L / H) measured up. Ordinary the Tianjin card water meter 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 people less than the starting flow of this drip Tianjin card meter not measured to obtain a table card online of water, so that the water supply enterprises have suffered losses. To solve this problem, Beijing Hui Yi has developed a differential pressure integral anti drip the Tianjin card meter, it simply does not change under the advance of the the Tianjin card meter movement in drip drop out of the water first accumulate, when the save suddenly a certain amount of promote Tianjin card meter rotating impeller to achieve the purpose of drip measurement ? Second, the product uses and characteristics: This series of Tianjin card water meter for the total amount of the high sensitivity to flow through a multi-card pipe drinking water, its main features are as follows: 1, the smaller the initial flow rate, the initial flow rate less than 0.5L / h; 16 times more than ordinary Tianjin card meter; 2, adaptability to water quality: the drainage channel between the anti-drip institutions and outlet distance of 4mm by 4mm below the particle, so that anti drip body will not be blocked or stuck by impurities in the water; 3, anti-slip performance: general movement is a multi-flow rate, not idling, soft diaphragm can offset part of the water hammer pressure, coupled with anti-drip closure of institutions , so its anti-creep performance is far superior to the jet and C-level anti-drip the Tianjin card meter; 4, in the 0.5L / h to 14L / h under the micro-flow state for the intermittent measurement (like displacement Tianjin 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 ? All the members of the Beijing Hui Yi Tianjin card water meter Co., Ltd. sincerely welcome you to Beijing the Huiyi Tianjin card meter factory guidance visits! ? |
