 ? Meter interface of the company R & D and production of pipe fittings price based on RF card as a form of media, a variety of information using the sensor's input to the meter interface fittings price controls CPU, the amount of water purchased by the meter interface fittings prices by user automatically open 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 interface pipe prices will automatically be within the electric valve off, Users only need to purchase water with the pipe price on the meter interface card write "sensing area to sense the meter interface fittings price of electric valve to re-open the remaining pipe fittings prices (ie, meter interface water is less than 5m3 to exhaustion this time, the meter interface fittings prices five times without water way to remind the user to purchase the water). If to the exhaustion of the remaining water in the pipe price of the meter interface, users do not share the price of the price of water and written to the meter interface fittings, electric valves will be closed until the user to purchase water and write the meter interface fittings. In order to achieve the first to buy the water, the purpose of water ". 
 ? M when the price of pipe of the meter interface exhausted in the remaining water and electric valve is closed, for some reason (such as electric valve internal leak, etc.) Pipe parts prices flow through the meter interface, the meter interface pipe prices will continue to be measured. number of total negative value when the users to purchase water and write the price of pipe of the meter interface, the interface of the water meter fittings price will first deduct the negative values ??(ie, the first overdevelopment of water), if water is not enough deductible newly written negative values ??of super-water, the water meter interface electric valve in the pipe price does not open and continue to be closed until the meter interface Pipe parts prices

 ? 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 electric valve is opened and the water meter interface pipe fitting normal price. 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 price of pipe attack the ability of the water meter interface, and limit the behavior so that it can not be infinite pipe price of the meter interface man-made attack. Produced by our company than any other meter interface fittings price of each within the multi-presented two of the company's trademark and warnings tamper shrink film, installation, pre-set into the take over on the meter interface fittings The price is installed and leak testing after passing tamper shrink film pipe prices in the meter interface 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 , which does not affect the verification and calibration of the meter interface fittings price accuracy; h. overall closed-shell design, anti-attack, waterproof, moisture, fumes, anti-knocking; i the sale of water to read and write card 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 GB GB/T778-1996 cold water meter interface fittings price "and the line marked CJ/T133-2006 water meter interface fittings price" standard. The water meter interface fittings, pipe prices About one the Huiyi brand meter interface price is developed in recent years for the ordinary meter interface fittings the price of a small flow (less than 8L / H) non-quantified defect. Ordinary water meter interface fittings price 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 at people can be less than the starting flow of this drip meter interface fittings 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 interface fittings price, it simply does not change the meter interface fittings price movement in advance, in drip drops out of the water first accumulated up when save to a certain amount meter interface fittings prices impeller rotation suddenly promoted to achieve the purpose of drip measurement 
 ? Two, the product uses and characteristics: This series water meter interface fittings 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; 16 times more than the price of ordinary meter interface fittings; 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 The anti-creep performance is far superior to the jet and C-level anti-drip meter interface pipe prices; 4, in the 0.5L / h to 14L / h under the micro-flow state for the intermittent measurement (like volume of water meter interface fittings price ), 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
