 ? Price of the company R & D and production of Hebei meter base table based on RF card as the media will be all kinds of information using the sensor in the form of input to control the CPU meter base table price in Hebei, Hebei meter base list price purchased by the user water automatically open the valve the water supply, 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, the price of 3m3, 2m3, 1m3) the Hebei meter base table will automatically within the electric valve is closed, the user simply purchase water into the the Hebei meter base list price of write card sensing area to sense the electric valve in the price of Hebei meter base table can be re-opened (ie, Hebei The remaining water in the meter base table price is less than 5m3 to the exhaustion of this time, the meter base list price of Hebei five times without water way to remind users to purchase water). If the remaining water to the price of the Hebei meter base table is exhausted, users do not share water and write the price the price of Hebei meter base table, the electric valve will close until the user to purchase water and write the Hebei meter base table inside so far. In order to achieve the first to buy the water, the purpose of water ". 
 ? M when the price of Hebei meter base table is exhausted in the remaining water and electric valve is closed, for some reason (such as electric valve internal leak, etc.), the price of water flowing through the the Hebei meter base table, Hebei meter base table prices will continue to measured, their number is counted as a negative value when the user to re-purchase of water and write the price of the the Hebei meter base table, Hebei meter base table price will first be less negative values ??(ie, the first also super water), if the new write the amount of water is not enough deductible super negative values ??of the water, the electric within the Hebei meter base table prices valve does not open and continue to be closed until the the Hebei meter base table Hebei meter

 Within the remaining water was 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 open and the normal work of Hebei meter base table prices. 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 do own to lift the price of Hebei meter base table attack, but also limit that it can not indefinitely human attack behavior of the prices of Hebei meter base table. The Company produced than the the Hebei meter base table price for each multi-presented two of the company's trademark and warnings tamper shrink film, installation, pre-set into the connector tube, Hebei The price of meter base table is installed and leak testing after passing tamper shrink film set in Hebei meter base table prices connector nut, and then use a hair dryer (1600w high heat hair dryer) at the tamper shrink film at blowing or at the tamper heat shrinkable film Pour hot water over 90 ℃, shrink film, shrink while the shape of the connector pipe 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 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 price accuracy verification and calibration of the the Hebei meter base table; 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 standards of GB GB/T778-1996 "cold water the Hebei meter base list price and the line marked CJ/T133-2006 Hebei meter base table price". A, Hui Yi brand Hebei meter base table price Hebei meter base table prices in recent years, small flows (less than the price of the ordinary the Hebei meter base table 8L / H) measured defect developed. Ordinary the Hebei meter base list price as a result of 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, and thus small flow can not be measurement, people can be less than the starting flow of this drip the Hebei meter base table prices not measured to obtain the water pipe line of water, so that the water supply enterprises suffered losses. To solve this problem, Hebei Hui Yi has developed a differential pressure integral anti-drip the Hebei meter base table price, simply does not change the Hebei meter base table under the advance of the price movement in drip drops out of the water first accumulated up when save a certain amount of a sudden promote the Hebei meter base table prices impeller rotation drip measurement purposes 
 ? Second, the product uses and characteristics: the price of this series the Hebei meter base table 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 of less than 0.5L / h; more than 16 times the price of ordinary Hebei meter base table; 2, adaptability to water quality: due to the drainage channel between the anti-drip institutions and outlet distance of 4mm, so the 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: general movement velocity, not idling, soft diaphragm can offset part of the water hammer pressure, coupled with anti-drip closure of institutions, Therefore, its anti-creep performance is far superior to the jet and C-level anti-drip the Hebei meter base list price; 4, in the 0.5L / h to 14L / h under the micro-flow state for the intermittent measurement (like displacement Hebei meter the price of the base table), 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
