 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 electric valve is opened and the price of a variety of meter base table to 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 ability to attack a variety of meter base table prices, but also limit that it can not indefinitely meter base table prices on a variety of man-made attack behavior. The Company produced more than other kinds of meter base table price for each multi-presented two of the company's trademark and warnings tamper shrink film, installation, pre-set connector fittings The price of a variety of meter base table is installed and leak testing after passing tamper shrink film sets the price of the base table in a variety of water meter connector pipe nut, then use the hair dryer (1600w high heat hair dryer) at the heat shrinkable tamper membrane at the blow or above 90 ℃ hot water poured aligned anti-demolition shrink film, 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 verification and validation of the accuracy of a variety of meter base table; h. overall closed-shell design, anti-attack, waterproof, moisture, fumes, 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 GB GB/T778-1996 "cold water variety of meter base table price and the line marked CJ/T133-2006 a variety of meter base list price" standard. A, Hui Yi brand a variety of meter base table Price brief introduction of the meter base list price is developed in recent years, small flows for the ordinary variety of meter base list price (less than 8L / H) measured at defects. Ordinary variety of meter base table price can not be due to the movement of 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 be measured, one can use the various meter base list price is not measured to obtain water of the water pipe-line is less than the starting flow of this drip, so that the water supply enterprises suffered losses. To resolve this issue, Hui Yi has developed a differential pressure integral anti-drip variety of meter base table price, it simply does not change the price movement of a variety of meter base table in advance, in drip drop out of the water first accumulate, When you save a certain amount of sudden promote a variety of meter base table prices rotating impeller to achieve the purpose of drip measurement 
 ? Second, the product uses and characteristics: the price of this series a variety of 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 at 0.5L / h; more than 16 times the price of the base table of the ordinary variety of meter; 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, thus so that 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 institutions closed , so its anti-creep performance is far superior to the price of jet and C-level anti-drip variety of meter base table; 4, 0.5L / h to 14L / h under the micro-flow state for the intermittent measurement (as if the volume the price of a variety of meter base table), 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
