 Shanxi pre-paid water meters ☆: 
 Company R & D and production of Shanxi pre-paid water meters, is the RF card as a form of media, a variety of information using the sensor's input to the the Shanxi pre-paid water meters control CPU, Shanxi, pre-paid water meters to the water purchased by the user to 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 the Shanxi pre-paid water meters automatically to the electric valve inside the Close Users only need to purchase water used to put Shanxi pre-paid meter card write "sensing zone" to the sensor can be Shanxi pre-paid water meters within the electric valve to re-open (ie, Shanxi, pre-paid water meters within the remaining water less than 5m3 to the exhaustion of this period, Shanxi, pre-paid water meters to 5 times without water way to remind users to purchase water). If to Shanxi prepaid the remaining water inside the water meter is exhausted, users do not purchase the water and write Shanxi prepaid water meter, electric valve will be closed until the user to purchase water and write the Shanxi pre-paid water meters within the date. In order to achieve the first to buy the water, the purpose of water ". 
 ? When Shanxi pre-paid water meters in the remaining water exhausted and electric valve is closed, for some reason (such as electric valve internal leakage, etc.) water pre-paid water meters by the Shanxi, Shanxi, 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 Shanxi pre-paid water meters, Shanxi 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, Shanxi pre-paid water meters within the electric valve does not open and continue to be closed until the Shanxi 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 be induced to purchase water card to (sensing area), you can own the electric valve to open and pre-paid water meters in Shanxi. 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 Shanxi ability to pre-paid water meters have been attacks, and limit the acts that it can not indefinitely Shanxi prepaid meter man-made attack. Produced by our company than other Shanxi 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, Shanxi prepaid water meter installed and leak testing after passing tamper shrink film take over the nut pre-paid water meters in Shanxi, 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 Shanxi, pre-paid water meter accuracy test and calibration; h, so as not to affect the 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 GB/T778-1996 "GB cold water Shanxi pre-paid water meter and the line marked CJ/T133-2006 Shanxi pre-paid water meters" standard.

 ? One, the Huiyi brand Shanxi pre-paid water meters Profile Shanxi prepaid meter is developed in recent years aimed at Shanxi pre-paid water meters in the micro flow (less than 8L / H) measured at defects. Ordinary the Shanxi 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 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 at people can be less than the starting flow of this drip Shanxi pre-paid water meters not measured to obtain the water of the RF 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 the Shanxi pre-paid water meters, simply does not change the Shanxi prepaid meter movement in advance, the drop out of the water in drip first accumulate when the save certain amount of time suddenly promote Shanxi prepaid water meter impeller rotation to achieve the purpose of drip measurement 
 ? Two, the product uses and characteristics: Shanxi pre-paid water meters 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 less than 0.5 L / h; is ordinary Shanxi 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 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 the C-class anti-drip Shanxi pre-paid water meters; 4, 0.5L / h to 14L / h under the micro-flow state for the intermittent measurement (like displacement Shanxi pre-paid water meters ), 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
