 R & D and production company Tunchang remote meter, RF card as the media will be all kinds of information in the form of an induction input to Tunchang remote meter control CPU Tunchang remote meter of water purchased by the user the water supply valve is automatically opened, when the remaining amount of 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 Tunchang remote meter will automatically within electric valve is closed, write cards "Users only need to purchase water into Tunchang remote meter sensing area to sense what you can Tunchang remote meter electric valve to re-open (ie Tunchang remote meter remaining water is less than 5m3 to exhaustion this time, the the Tunchang remote meter five times without water way to remind the user to purchase the water). To the the Tunchang remote meter within the remaining water is exhausted, the user is less than the purchase of water and write Tunchang remote meter, electric valve will close until the user to purchase water and write Tunchang Far EasTone meter inside so far. In order to achieve the first to buy the water, the purpose of water ". 
 ? Tunchang remote meter exhausted in the remaining water and electric valve is closed, for some reason (such as electric valve internal leakage) flow through the Tunchang remote meter Tunchang remote meter will proceed measurement, the number of dollars for a negative value, when the user to re-purchase of water and write Tunchang remote meter, the the Tunchang remote meter will first less negative values ??(ie, the first also super water), if the new write enough water deductible super negative values ??of the water the Tunchang remote meter electric valve does not open and continue to be closed until the remaining water Tunchang remote 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 the electric valve to open and the Tunchang remote 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-lifting of the the Tunchang remote meter attack the ability to limit that it can not indefinitely Tunchang remote meter man-made attack behavior. Produced by our company, donated more than other Tunchang remote water meter for each two of the company's trademark and warnings tamper shrink film, installation, pre-set into to take over, will Tunchang remote meter installed and leak testing after passing tamper shrink film set in the the Tunchang remote meter to take over the nut, and then use a hair dryer (1600w high heat hair dryer) at the tamper shrink film at blowing or Pour hot water above 90 ℃ alignment tamper shrink film, shrink film, shrink to take over the shape of the nut to tight coupling. 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 carriers, electronic 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 measurement display using electronic and LCD Dual Display , which does not affect the the Tunchang remote meter accuracy test and calibration; h. overall closed-shell design, anti-attack, waterproof, moisture, fumes, anti-knocking; i the sale of water to read and write card machine can separate use, 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 Tunchang remote meter line marked CJ/T133-2006 in Tunchang remote meter standard.

 ? A, Hui Yi brand Tunchang remote meter Introduction Tunchang remote meter is developed in recent years aimed at Tunchang remote meter small flows (less than 8L / H) measured defects. Ordinary Tunchang remote meter due to movement of the rotating parts and count the gear inertia, and therefore 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, to the small flow can not be measurement, it can be used less than the starting flow of this drip Tunchang remote meter access is not measured at the water tube online, so that the water supply enterprises suffered losses. To solve this problem, Beijing Hui Yi has developed a pressure differential integral anti-drip Tunchang remote meter, simply does not change Tunchang remote meter movement in advance, in drip drops out of the water first accumulated up when save a certain amount of a sudden promote Tunchang remote meter impeller rotation to achieve the purpose of drip measurement 
 ? Second, the product uses and characteristics: This series of Tunchang remote meter for the total amount of the high sensitivity to flows through the tube 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 Tunchang remote 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 Tunchang remote meter; 4, in the 0.5L / h to 14L / h under the micro-flow state for the intermittent measurement (as if the displacement Tunchang far pass meter), and micro-flow range measurement error is small; 5, convened by the Ministry of Construction and the China Water Association, China's authoritative experts on the products and technologies were identified, 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
