 Shandong water meter ☆: 
 Company R & D and production in Shandong water 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 Shandong water meter, water the Shandong tap water meter purchased by the user automatically open the valve the water supply, the remaining 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) Shandong water meter will automatically power within its valve closed, the user only with the purchase of water into the water meter in Shandong write card sensing area to sense re-open the electric valve in the water meter within Shandong (Shandong water meter within the remaining water is less than 5m3 to the exhaustion of this period of time, Shandong Water meter five times without water way to remind users to purchase water). To the exhaustion of the remaining water in the water meter within Shandong, users do not purchase water and write Shandong water meter, electric valve will be closed until the user to purchase water and write Shandong water meter within the date. In order to achieve the first to buy the water, the purpose of water ". 
 ? Shandong water meter is exhausted in the remaining water and electric valve is closed, for some reason (such as electric valve internal leakage, etc.) the flow through the water meter when Shandong, Shandong water meter will continue to be measured, the number counted as negative values, when the users to purchase water and write Shandong water meter, Shandong water meter 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 Shandong water meter, electric valve to open and continue to be closed until the remaining water in the water meter within Shandong 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 Shandong water meter 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 to lift Shandong water meter attack, but also to limit the behavior that it can not indefinitely Shandong water meter man-made attack. The Company produced more than other Shandong water meter each presented two of the company's trademark and warnings tamper shrink film, installation, pre-set into to take over, Shandong water meter installation completed and leak testing and qualified, tamper shrink film took over the nut of the water meter in Shandong, and then use the hair dryer (1600w high heat hair dryer) at the tamper shrink film at the blow 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, 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 , which does not affect the Shandong water meter accuracy test and calibration; 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, can also use the computer network. 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 Shandong water meter and the line marked CJ/T133-2006 "Shandong water meter".

 ? A Huiyi brand Shandong water meter Shandong water meter in recent years for ordinary the Shandong tap water meter in the tiny flow (less than 8L / H) the development of non-quantified defect. Ordinary Shandong 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 Shandong water meter not measured to obtain the water pipe line of water, so that the water supply enterprises suffered losses. To solve this problem, Beijing Hui Yi has developed a differential pressure integral anti-drip Shandong water meter, it simply is not changed in advance of the Shandong water meter movement in drip drop out of the water first accumulate, save to a certain amount of suddenly promote Shandong water meter impeller rotation to achieve the purpose of drip measurement 
 ? Second, the product uses and characteristics: This series of Shandong water meter for the total amount of the high sensitivity of flows through a water pipe drinking water, its main features are as follows: 1, the smaller the initial flow rate, the initial flow rate of less than 0.5L / h; 16 times more than ordinary Shandong water meter; adaptability to water quality: due to the drainage channel between the anti-drip institutions and outlet distance of 4mm, by particles below 4mm, so that the anti-drip institutions will not be 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 institution, so the anti-creep performance far superior to the jet and C-class anti-drip Shandong water meter; 4, 0.5L / h to 14L / h under the micro-flow state for the intermittent measurement (like displacement Shandong water meter), and micro- the flow range of measurement error; 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 the leading domestic 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
