 Hainan remote meter ☆: 
 R & D and production company in Hainan remote meter, RF card as the media, all kinds of information in the form of an induction input to the Hainan remote meter control CPU, Hainan remote meter of water purchased by the user 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) Hainan remote meter automatically inside the electric valve shut down Users only need to purchase water use at this time to write cards into Hainan remote meter sensing area to sense what the electric valve in the Hainan remote meter re-open the remaining amount of water (ie, Hainan remote meter less than 5m3 to exhaustion this time, the Hainan remote meter five times without water way to remind users to purchase water). To the exhaustion of the remaining water in the Hainan remote meter, if the users do not purchase water and write Hainan remote meter motorized valve will close until the user to purchase water and write within the date of Hainan remote meter. In order to achieve the first to buy the water, the purpose of water ". 
 ? When Hainan remote meter exhausted in the remaining water and electric valve is closed, for some reason (such as electric valve internal leakage) currents when the remote meter by Hainan, Hainan, remote meter will continue to be measured, the count of the number of negative values ??when the user to re-purchase of water and write the Hainan remote meter, Hainan remote meter will first deduct the negative values ??(ie, the first overdevelopment of water), if the amount of water newly written enough deductible super negative values ??of the water, Hainan remote meter electric valve does not open remain closed until the remaining water in Hainan 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 Hainan 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 Hainan remote meter attack ability, but also to limit the behavior that it can not indefinitely Hainan remote meter man-made attack. Produced by the Company, presented two of the company's trademark and warnings tamper shrink film more than other Hainan remote water meter for each installation on its pre-set into the receiver, the Hainan Far EasTone water meter installed and leak testing after passing tamper shrink film took over the nuts in Hainan remote meter, 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 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 , thus does not affect the verification and validation of Hainan remote meter accuracy; 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 the GB GB/T778-1996 cold water Hainan remote meter line marked CJ/T133-2006 Hainan remote meter standard.

 ? A, Hui Yi brand Hainan remote meter Introduction to Hainan remote meter is defective development in recent years aimed at Hainan remote meter small flows (less than 8L / H) measured up. Ordinary Hainan remote 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 way make Hainan remote meter access is not measured at the water tube online, so the water supply enterprises have suffered losses. To solve this problem, Beijing Hui Yi has developed a pressure differential integral anti-drip Hainan remote meter, it simply is not changed the Hainan remote meter movement in advance, in drip drop out of the water first accumulate when the save suddenly promoted a certain amount of Hainan remote meter rotating impeller to achieve the purpose of drip measurement 
 ? Second, the product uses and characteristics: This series of Hainan 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 of less than 0.5L / h; more than 16 times the ordinary Hainan remote meter; 2, adaptability to water quality: due to the drainage channel between the anti-drip institutions and outlet distance of 4mm, so 4mm below the particle, so that the anti-drip institutions are not will be clogged by impurities in the water or get stuck; 3, anti-slip performance: general movement velocity, 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 is far superior to the jet and the C-class anti-drip Hainan remote meter; 4, in the 0.5L / h to 14L / h under the micro-flow state for intermittent measurement (like displacement Hainan remote meter the same) and micro-flow range measurement error is small; 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 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
