 Tianjin meter factory ☆: 
 Our R & D production in Tianjin meter plant, based on RF card as the media will be all kinds of information in the form of an induction input to control the CPU meter factory in Tianjin, Tianjin meter factory the amount of water purchased by the user automatically open the valve the water supply when 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) Tianjin meter factory automatic electric valve in its closed, the user only for the purchase of water on the water meter factory in Tianjin to write the card sensing area to sense can re-open the electric valve of the water meter factory in Tianjin (Tianjin meter factory remaining water is less than 5m3 to the exhaustion of this period of time, Tianjin's water meter factory five times without water way to remind users to purchase water). If, to the exhaustion of the remaining water meter factory in Tianjin, the users do not purchase water and write Tianjin meter factory, the motorized valve will close until the user to purchase water and write until the Tianjin meter factory. In order to achieve the first to buy the water, the purpose of water ". 
 ? When Tianjin meter factory is exhausted in the remaining water and electric valve is closed, for some reason (such as electric valve internal leakage) flow through the Tianjin meter factory, Tianjin meter plant will continue to be measured, the number counted as negative values ??when the user re-purchase of water and write the Tianjin water meter factory, Tianjin meter plant 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 meter factory in Tianjin electric valve open continue to be closed until the remaining water meter factory in Tianjin 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 to open and work properly, Tianjin meter factory. 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 to lift Tianjin meter factory attack, but also limit that it can not indefinitely assault of man-made water meter factory in Tianjin. Produced by our company, the other the Tianjin meter factory each multi-presented two of the company's trademark and warnings tamper shrink film, installation, pre-set into to take over, Tianjin meter factory installation completed and leak testing and qualified, tamper shrink film took over the nut of the water meter factory in Tianjin, and then use a hair dryer (1600w high heat hair dryer) Shrink Film Department at the tamper blowing 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, 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 dual LCD display, so as not to affect the accuracy of the Tianjin meter factory test and calibration; h overall closed-shell design, anti-attack, waterproof, moisture-proof, anti-smoke, anti-knocking; i its sale of water to read and write 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 standards of GB GB/T778-1996 cold water Tianjin meter factory and the line marked CJ/T133-2006 "Tianjin meter factory".

 ? One, the Huiyi brand Tianjin meter factory Introduction Tianjin meter factory defects in development in recent years for ordinary the Tianjin meter factory in the small flow rate (less than 8L / H) measured up. Ordinary the Tianjin meter factory due to the movement of the rotating parts and count the gear inertia, so in the measurement process, if the water flow is small to a certain degree 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 Tianjin meter factory measurement of water to obtain a multi-card tube online, so that the water supply enterprises suffered losses. To solve this problem, Beijing Hui Yi has developed a differential pressure points anti-drip the Tianjin meter factory, it simply does not change the movement in advance of the Tianjin water meter factory in drip drop out of the water first accumulate, save to a certain amount of suddenly promote Tianjin meter factory impeller rotation drip measurement purposes 
 ? Two, the product uses and characteristics: This series of Tianjin meter factory 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 at 0.5L / h; more than 16 times the ordinary Tianjin meter plant; 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 the C-class anti-drip Tianjin meter factory; 4, in the 0.5L / h to 14L / h under the micro-flow state for the intermittent measurement (like displacement Tianjin meter factory) 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
