 Our R & D production in Tianjin electronic meter, based on RF card as the media will be all kinds of information in the form of an induction input to the control CPU of the electronic meter in Tianjin, Tianjin electronic meter of water purchased by the user automatically open the valve the water supply, the 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) Tianjin electronic meter will automatically within the electric valve closed, the user only with the purchase of water into the electronic meter in Tianjin write card sensing area to sense can re-open the electric valve Tianjin electronic meter (Tianjin electronic meter, the remaining water is less than 5m3 to the exhaustion of this period of time, Tianjin electronic meters alert the user to purchase water) five times without water way. To the exhaustion of the remaining water in Tianjin electronic meter, if the users do not purchase water and write Tianjin electronic meter, electric valve will be closed until the user to purchase water and write Tianjin electronic water meters within the date. In order to achieve the first to buy the water, the purpose of water ". 
 ? Tianjin electronic meter is exhausted in the remaining water and electric valve is closed, for some reason (such as electric valve internal leakage) flow through the meter Tianjin Electronics, Tianjin electronic meters will continue to be measured, the number counted as negative values, when the users to purchase water and write Tianjin electronic meter, Tianjin electronic meters 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 Tianjin electronic meters of electric valve does not open and continue to shut down, until the remaining amount of water in Tianjin electronic meter is 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 Tianjin electronic meters 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). So not only do self-lifting capacity of Tianjin electronic meter attack, limit the behavior so that it can not be unlimited electronic meters in Tianjin human attacks. The Company produced more than other Tianjin electronic water meters for each presented two of the company's trademark and warnings tamper shrink film, installation, pre-set into to take over, Tianjin electronic water meter installation completed and leak testing and qualified, tamper shrink film set in the electronic meter in Tianjin took 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 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, which does not affect the Tianjin electronic test and calibration of the meter accuracy; 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 the the GB GB/T778-1996 cold water Tianjin meter line marked CJ/T133-2006 "Tianjin E-meter" standard.

 ? A, Hui Yi brand Tianjin electronic meter Introduction to Tianjin electronic meter is developed in recent years aimed at Tianjin electronic meters in a small flow (less than 8L / H) measured at defects. The ordinary Tianjin electronic water meter 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 people can be less than the starting flow of this drip Tianjin electronic water meter is not metering 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 integral anti-drip Tianjin electronic meter, it simply does not change under the advance of the Tianjin electronic meter movement in drip drop out of the water first accumulate, save to a certain amount of suddenly promote Tianjin electronic meter impeller rotation to achieve the purpose of drip measurement 
 ? Second, the product uses and characteristics: This series of Tianjin electronic water meters for the total amount of the high sensitivity of the 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 electronic 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 far superior to the jet and C-level anti-drip Tianjin Electronic meter; 4, in the 0.5L / h to 14L / h under the micro-flow state for intermittent measurement (as if the displacement Tianjin electronic meter) 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
