 ? Took over my company R & D and production meter copper price, based on RF card as media, enter all kinds of information in the form of an induction meter copper to take over the price control CPU meter copper took over the price of water purchased by the user is automatically opened the water supply valve, when 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) when the meter copper takeover price will be automatically inside the motorized valve Close, Users only need to purchase water used to take over the price card write "sensing area to sense will take over the price of the meter copper electric valve re-open (ie meter copper takeover price on the meter copper remaining water is less than 5m3 to exhaustion during this time, took over the price of water meter copper five times without water way to remind users to purchase water). To meter copper to take over the exhaustion of the remaining amount of water price, the users do not purchase the water and written to the meter copper took over the price, the motorized valve will close until the user to purchase water and write inside until the meter copper takeover price. In order to achieve the first to buy the water, the purpose of water ". 
 ? M take over the price of water meter copper is exhausted in the remaining water and electric valve is closed, for some reason (such as electric valve internal leakage, etc.) as well as take over the price of water flowing through the meter copper meter copper takeover prices will continue to be measured. number of total negative value when the user to re-purchase of water and write the price of the meter copper takeover meter copper took over the price will first deduct the negative values ??(ie, the first overdevelopment of water), water newly written enough deductible negative values ??of super-water, the water meter copper to take over the price of electric valve does not open and continue to be closed until the water meter copper took over the price

 ? Within the remaining water 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 take over the price of water meter copper 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 ability to take over the price of water meter copper attack and limit the behavior so that it can not be infinite human attack to take over the price of the meter copper. Produced by our company, each presented a more two of the company's trademark and warnings tamper shrink film taken over than any other meter copper price, installation, on its pre-set into the receiver will take over the water meter copper price installed and leak testing and qualified, tamper shrink film sets to take over the water meter copper price 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 meter copper, which does not affect the take over price accuracy verification and validation; 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 standards of GB GB/T778-1996 copper take over the price of cold water meter and line marked CJ/T133-2006 meter copper took over the price ". A, of Huiyi brand water meter copper to take over take over the price of the price About meter copper in recent years to take over the price for ordinary meter copper in the small flow rate (less than 8L / H) measured defects developed. Ordinary water meter copper took over the price 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 meter copper to take over price not measured to obtain the water of the water pipe-line, so that the water supply enterprises suffered losses. To resolve this issue, Hui Yi has developed a differential pressure integral anti-drip meter copper to take over the price, it simply is not to change the meter copper to take over the price movement in advance, the drop out of the water in drip first accumulate when save to a certain The amount of suddenly promoted meter copper to take over the price of the rotating impeller to achieve drip measurement purposes 
 ? Two, the product uses and characteristics: This series water meter copper takeover price 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 is less than 0.5 L / h; more than 16 times the copper take over the price of ordinary water 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 anti-creep performance is far superior to the jet and C-level anti-drip meter copper took over the price; 4, 0.5L / h to 14L / h under the micro-flow state to take over for the intermittent measurement (as if the volume meter copper prices ), 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
