 Shanxi card meter ☆: 
 Our R & D production the Shanxi card meter based on RF card as a form of media, a variety of information using sensing input to the control CPU of the of Shanxi card meter, the Shanxi 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) the Shanxi card meter automatically the electric valve inside the Close Users only need to purchase water use at this time write into the of Shanxi card meter card sensing area to sense Shanxi card water meter electric valve can be re-open the remaining water (ie, the Shanxi card meter less than 5m3 to the exhaustion of this period, Shanxi card meter five times without water way to remind the user to purchase water). To the exhaustion of the remaining water in the Shanxi card water meter, not the purchase of water and write the Shanxi card water meter, electric valve will close until the user to purchase water and write Shanxi card water meter within the date. In order to achieve the first to buy the water, the purpose of water ". 
 ? After Shanxi card water meter is exhausted in the remaining water and electric valve is closed, for some reason (such as electric valve internal leakage) currents card meter by Shanxi, Shanxi card meter will continue to be measured, the count of the number of negative values, when the user re-purchase of water and write Shanxi card meter, the the Shanxi card water meter will first deducting the negative values ??(ie, the first overdevelopment of water), water newly written enough deductible super negative values ??of the water, Shanxi card water meter electric valve does not open remain closed until the remaining amount of water in the Shanxi 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 Shanxi card water 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 do self-lifting the Shanxi card water meter has been the ability to attack, but also limit that it can not indefinitely Shanxi card water meter man-made attack behavior. Produced by our company, multi-presented two of the company's trademark and warnings tamper shrink film than any other the Shanxi card meter for each installation, pre-set into to take over, Shanxi cassette water meter installed and leak testing after passing tamper shrink film set in Shanxi card meter to take over the nut, and then use a 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, 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 and thus do not affect the verification and validation of the Shanxi card water meter accuracy; 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 , 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 Shanxi card water meter and the line marked CJ/T133-2006 the Shanxi card meter "standard.

 ? A Huiyi brand About Shanxi, Shanxi card meter card meter in recent years for ordinary Shanxi card meter in micro flow (less than 8L / H) non-quantified defect developed. Ordinary the Shanxi 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 Shanxi card meter not measured to obtain the water of the RF tube online, 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 Shanxi card meter, it simply does not change, the advance of the the Shanxi card meter movement in drip drop out of the water first accumulate, when the save a certain amount of a sudden promote Shanxi card meter impeller rotation reach dripping measurement purposes 
 ? Second, the product uses and characteristics: This series of Shanxi card water meter for the total amount of the high sensitivity of flowing through the RF pipe drinking water, its main features are as follows: 1, the smaller the initial flow rate, the initial flow rate is less than 0.5 L / h; more than 16 times the ordinary Shanxi card 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 not by impurities in the water is clogged or stuck; 3, anti-slip performance: ordinary movement is the flow rate, not idling, soft diaphragm can offset part of the water hammer pressure, coupled with anti-drip closure of the institutions, so the The anti-creep performance is far superior to the jet and C-level anti-drip the Shanxi card water meter; 4, in the 0.5L / h to 14L / h under the micro-flow state for the intermittent measurement Shanxi card (like a positive displacement meter ), and micro-flow range measurement error is smaller; 5, of the authority of experts convened by the Ministry of Construction and the China 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
