 Chongqing RF meter ☆: 
 R & D and production company, Chongqing RF water meter, based on RF card to the Chongqing RF water meter the amount of water purchased by the user automatically open valve to control the CPU of the of Chongqing RF meter, as the media will be all kinds of information in the form of an induction input 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) Chongqing RF meter will automatically inside the electric valve Close , this time written into the of Chongqing RF meter Card Users only need to purchase water sensing area to sense the the Chongqing RF water meter, electric valve can be re-open the remaining water (ie, Chongqing RF meter less than 5m3 to exhaustion this time, Chongqing RF meter five times without water way to remind users to purchase water). To the water remaining in the Chongqing RF water meter is exhausted, the user not to purchase water and write Chongqing RF meter, the electric valve will close until the user to purchase water and write Chongqing RF water meter within the date. In order to achieve the first to buy the water, the purpose of water ". 
 ? When Chongqing RF water meter is exhausted in the remaining water and electric valve is closed, for some reason (such as electric valve internal leakage) flow through the Chongqing RF meter, Chongqing RF water meter will continue to be measured, the the number counted as a negative value when the users to purchase water and write the Chongqing RF water meter, the the Chongqing RF meter will first deduction of the negative values ??(ie, the first overdevelopment of water), if the amount of water newly written enough deductible super negative values ??of the water, Chongqing RF water meter, electric valve does not open remain closed until the remaining water in Chongqing RF water 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 purchase water card to (sensing area) induction can own electric valve open and to Chongqing RF 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). So not only do the self-lifting the Chongqing RF water meter attack, but also to limit the behavior that it can not indefinitely Chongqing RF water meter man-made attack. Produced by our company, donated more than other of Chongqing RF water meter each two of the company's trademark and warnings tamper shrink film, installation, on its pre-set into the receiver, Chongqing, RF water meter installed and leak testing after passing tamper shrink film set to take over in of Chongqing RF meter 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, RF-type wear, fast transmission of information, confidentiality and anti-attack performance, high reliability; (b) the use of LCD LCD the total quantities of water purchased, and 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, static power consumption is zero; (e) electronic 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. measurement shows the RF type and LCD dual display, so as not to affect the of Chongqing RF meter accuracy test and calibration; h. overall closed-shell design, anti-attack, waterproof, moisture, anti-smoke, anti-knocking; i water sales to read and write card machine 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 GB GB/T778-1996 cold water Chongqing RF water meter and line marked CJ/T133-2006 Chongqing RF meter standard.

 ? A, Hui Yi brand RF type meter Introduction of Chongqing, Chongqing, RF meter in recent years for the ordinary Chongqing RF water meter in a small flow (less than 8L / H) is not measured defect developed. Ordinary Chongqing RF 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 can be less than the starting flow of this drip Chongqing RF meter 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 Chongqing RF water meter, it simply is not to change the the Chongqing RF meter movement in advance, the drop out of the water in drip first accumulate when the save suddenly promoted a certain amount of The Chongqing RF meter rotating impeller to achieve the purpose of drip measurement 
 ? Two, the product uses and characteristics: This series of of Chongqing RF 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 of less than 0.5L / h; more than 16 times the ordinary Chongqing RF 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 is far superior to the jet and the C-class anti-drip Chongqing RF meter; 4, 0.5L / h to 14L / h under the micro-flow state for the intermittent measurement (like displacement Chongqing RF meter ), and micro-flow range measurement error is small; 5, of the authority of experts convened by the Ministry of Construction and 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
