When the remaining water is less than 2 cubic meters, the audible alarm is given, while closing the valve, then plug the user card can open the valve, prompting timely purchase of water and when the remaining water is zero, close the valve, open the card user to re-purchase water valve water. meter factory in Shaoguan Smart IC card technology Shaoguan measured water consumption and water data transfer and settlement transactions of the new water meter with conventional flow meter usually has only collected water and mechanical function pointer display compared to a lot of progress. intelligent smart meter In addition to water can be recorded and electronic display, you can also control the amount of water according to the agreed on, and automatically calculate the price ladder for water, while water data storage capabilities. meter installation; ① meter diameter should Depending on the installation pipe diameter, depending on the installation location should avoid exposure, flooding, freezing and pollution, easy disassembly and swipe. ② meter shall be horizontal (display facing up) installed. ③ newly installed pipes should be preceded by clear gravel, flax and other debris to avoid water failure. ④ meter direction of the arrow shown in the flow direction should be consistent with the pipeline. ⑤ If the meter installed in the boiler feed water side, the hot water and steam boilers to prevent backflow of water damage to internal parts , preferably water meter installed at the outlet check valve. Meizhou meter factory / Affordable Housing meter / meter factory / price which from 1825 British Ke Lusi invented a truly balanced characteristics since the tank meter, water meter development for nearly two hundred years of history, China's water use and production started late 1879, Li was make arrangements for the Navy, created China's first waterworks. 1883 British colonialists in the establishment of a second water, water began to enter China With some coastal cities have been built waterworks, to the 20th century era, (formerly) imported from abroad, such as some of the parts produced water meter for a long time, such as Japan, Germany, Britain and France has been dominated by the meter China's water industry, these different varieties and specifications meter complex, because different standards, parts are not interchangeable, since the water company to repair a meter brought great difficulties. meter after 1949, with the city water utilities the development of China's water industry has also developed accordingly. Meizhou meter factory / Affordable Housing meter / meter factory / price which is not from 1955 onwards, Shanghai, Beijing, Tianjin, Nanjing, Wuhan, Guangzhou and other cities have water company began producing water meter. early 1980s, water industry in the Ministry of Machinery Industry Industrial Automation Instrumentation, Shanghai Institute of organization, according to the prevailing requirements of ISO4046 international standard water meter, water meter for small caliber launched eight pointer, the overall national impeller unified design of the meter. universal design and plastic parts of the meter, water meter specialized production organization created favorable conditions, which greatly promoted China water meter industrial progress and development to meet the growing demand for industrial development in urban and rural water supply. Shaoguan Smart meter in the 1990s, China's sustained and rapid development of economic construction, water industry also developed rapidly, and the total number of enterprises have more than doubled, while a variety of intelligent water meter, water meter reading system and other products have begun to rise. accurate metering can save resources, please select the regular large production meter. meter prospects 1 measuring meter high rank with the high level of water metering, including the micro flow meter can, including a large flow range, also fundamentally truly improve the water sensitivity and measurement capabilities. piston (also known as displacement) meter measurement hierarchy generally up to C or D grade, but higher water quality requirements. Explanation: Most countries require the use of international to measure and grade B above water, the domestic industry has canceled the meter metering grade A voice in the formulation of this new international standard meter and international recommendations, also based on the principle of electromagnetic or electronic work, used to measure the water The flowmeter is also included in the water meter. 2. remote meter reading and computer outdoors property management combines remote meter water meter and water meter secondary instrument matching is promising, because it improves the water meter reading method to improve the information technology \ digitization and automation, reducing the use of water meters disturb users and security concerns. implemented parts of the country, also uses this type of meter. Currently, the mainstream products mainly include photoelectric direct reading meter , resistive direct-reading meter, wireless remote table, GPRS real-time traffic monitoring large tables and other forms. First, the current state of technology direct-reading meter reading system of the present wireless and wired meter reading two kinds. wired 485 transmission mode and M-BUS transmission two kinds. transmission 485 the main characteristics of four lines (two power lines, two signal lines), to distinguish the polarity; M-BUS transmission main features are two lines, not only do they add a power signal, and two lines, regardless of polarity. wired meter in accordance with the technology in different ways, can be divided into pulse (active), camera type (passive), the resistance type (passive), photoelectric (passive) from the technical reliability of the direction of development and market share is concerned, is the current mainstream photoelectric way. Shaoguan IC meter direct reading meter is the meaning usually not powered, meter reading when the power meter. drawings Rieter Zhejiang Yi Industrial Co., Ltd. modules and direct-reading meter picture.

Typical products include IC card water meter (card or inductive), TM card water meter, code switching pre-paid water meters. induction IC card IC card table card table 4. backflow meter or two-way metering current domestic water meter is generally a single flow meter, mostly in reverse flow (also known as the back or reverse flow) can also be walking around and make the cumulative reduction in the number of existing agencies did not prevent the water meter seals Flip function, so there is cause metering disputes and the possibility of cheating. backflow water table by the entrance to the installation of check valves can be connected over the water meter seal together to prevent a man-made flip-meter and the possibility of cheating Bidirectional water meter function is in reverse flow meter counting mechanism is still accumulating and consistent with measurement accuracy requirements. Explanation: The current national standards for backflow meter or two-way metering meter no detailed provisions, requiring only meter can "withstand accidental countercurrent countercurrent and show this amount." structural principle of the traditional meter meter meter structure tradition traditional water from outside to inside the internal structure can be divided into the housing, the sleeve, the inner core Big Three. shell is raw cast-iron into the water came out from the inlet through the housing of the lower annular space, this is called "the ring chamber." In the annular space above the "upper annulus" and outlet connected. with the bottom of the sleeve has a orifice filter, filter out debris in the water. sleeve up and down two rows of side hole, the hole position coincided with the upper and lower casing annulus chamber facing, obviously, the next row is a water hole, the upper row is water hole is particularly worth noting that the two rows of holes are at an angle along a direction tangent to the circle play Note the upper and lower rows of holes in the opposite direction of water from the lower row of holes flow into a tangential direction, is bound to a swirling flow, This meter is very important work. inner core is divided into upper, middle and lower layer, seen from the upper windows, only pointers and dials. Actually, the most critical is lower, and there are two plastic wheels , round the edge of a lot of plastic blade impeller location right in the hole formed by the lower casing rotating flow, the current rush week vane wheel, producing torque, the rotor spin. faucet open the bigger, the water flow The more urgent, the impeller to turn faster. impeller shaft vertically upward to reach the middle, there is a small gear shaft above, use it and the "decimal gear" engagement, reaching the purpose of the cumulative number of revolutions. "Decimal gear" role is Whenever digit gears turn ten laps, ten-digit gear on the revolution in other words, the single digits gear revolution, tens tenths of gear to turn around. single digits by the gear is active , sufficient to drive the gear ten digits. virtually every level decimal completion of two pairs of gears to the rotating direction, one of the drive ratio is 9:30, and the other pair is 10:30, the two pairs of connected in series, the total transmission ratio is the product of these two, namely 0.099999, can be approximated as 0.1. according to this calculation, if you want to read seven numbers (before the decimal point is read four black mark, after the decimal point is read three red scale), you have to use 12 pairs of gears coupled with some other purpose, in this small space to squeeze the middle axis 18 and 34 gears, can also be regarded as a high-density mounting and such water by virtue of its simple and inexpensive, can be used in wet environments without the need for long-term maintenance, and do not supply, power does not affect the work of the advantages will still be long term. meter readings that I believe many people still confused, here to introduce its readings now home residents meter mechanical meter, dial generally have eight pointers showing the value of standard disk shown in Figure 1, showing the value of the right side of four red pointer Odds: × 0.1, × 0.01 ...... are less than one cubic meter showing the value, because the tap water metering unit is "cubic" these standard disk generally does not have practical significance, you can not recognize and read. left four black pointer showing the value of standard disk × 1, × 10 ...... is the basis for water metering and charging, the reader should learn to recognize and read Figure 1 recognition to recognize and read pointer when the pointer must first understand the four black units and their rounding in Figure 1 showing the value of four black pointer standard disk counterclockwise from the top, followed by a digit pin (× 1), ten-pin (× 10), one hundred needles (× 100), one thousand needles (× 1000). × 1 pointer revolution , × 10 pointer walked a word; × 10 pointer revolution, × 100 pointers to go one word; × 100 pointer revolution, × 1000 pointer to go a word. recognize and read the essentials to recognize and read the meter, to from high to low in order to recognize and read pointer, from × 1000 showing the value of standard disk pointer clockwise to recognize and read from the bottom upwards. particular note: If one thousand, one hundred, ten pointer position between the two figures , pay attention to the upper and lower two adjacent pointers associated with it. like shown in Figure 2, "× 10" ten-bit pointer between 8 and 9, very close to 9 and is the R 8 or R 9, depending on the The bits × 1 standard disk pointer is to 0, we see a bit pointer is between 0 and 9, that is not binary, so ten pointer should read 8, rather than reading 9. If bits pointer pointing between the two figures, depending on the side next to the red pointer × 0.1 standard disk is too "5", take 4 5 homes means to determine whether the binary bits pointer shown in Figure 3 × 0.1 standard disk pointer is not over, "5", and a bit pointers between 0 and 9, this time should not carry, a bit should read "9." smart IC card water meter IC card water meter is a smart use of modern microelectronic technology, modern sensing technology, smart IC card technology for measurement of water consumption and water data transfer and settlement transactions of the new meter, which generally has a conventional flow meter collection and mechanical function pointer display compared to water is a great progress. Intelligent IC card water meter for water in addition to recording and electronic display, you can also automatically accordance with the contract for water control and water bills automatically calculate the price ladder, while water data storage capabilities. Due to its meter data transfer and settlement of transactions carried out through the IC card, which can be achieved by the door staff charged to the user's own operating table to the payment of business transformation. IC card transaction system also has to facilitate transactions, and accurate calculation can be settled using the bank Features. IC card water meter water meter and the general appearance of similar appearance, the installation process is basically the same. IC card water meter is very simple to use, from the user's point of view, it is time to water the IC card chip inserted inside look. IC card meter working process is generally as follows: The amount of the IC card is inserted containing a water meter IC card reader, the computer module identifies and download amounts, the valve opens, the user can normal water when the users of water, the water collecting device starts water is collected and converted into electrical signals supplied to the microcomputer desired metering module, and the module is displayed on the LCD display when the user decreased the amount of water to a certain value, the microcomputer module sound alarm, the user should be prompted to hold the card payment to purchase water, such as over water amount, the microprocessor module electrically controlled valve will automatically shut down, cutting off the water supply. until the user inserts the IC card payment has been restarted on the water supply valve. Edit this paragraph meter breed type 1 Press Measuring principle points into speed and volumetric water meter water meter. (1): installed in a closed in by a movement components, gained momentum by making direct flow velocity meter. typical speed of a water meter. rotor type water meter and there were single-jet water meter and multi-jet water meter Lo Wing-meter (2): Installation in the pipeline, and by some to be successively filled with a known volume of fluid discharge chamber and a fluid-driven institutions by virtue of a meter , or simply quantified emission-type water meter Volumetric water meter generally use piston-type structure. 2 Press LEVEL measured by old standards, can be divided into A-level tables, B grade table, C-level table, D scales. measurement level reflects the work flow meter range, especially under low flow measurement of performance according to the order from low to high, generally divided into A-level tables, B grade table, C-level table, D scales, the measurement of performance reached the national standard specified measurement level A, B, C, D grade corresponding requirements after the release of the new standard, measurement classification method becomes quite complex, mainly according to the flow value and the turndown ratio and other parameters to determine. Simply put, the more range large, the higher the level measurement. 3 divided by the nominal diameter of large diameter water meter, water meter small-caliber Press usually divided into small and large caliber caliber water meter with a nominal diameter of 50mm and below the water meter is usually known as the small caliber water, nominal diameter of 50mm or more large caliber water meter called this two kinds of water meter is sometimes called civil and industrial water table, and this kind of law of the case can also be connected from the meter to distinguish the form of a nominal 50mm and below meter with a threaded connection, 50mm and above water meter flanged, but some also have a special type of water meter 40mm flange connection. 4 divided by Use of civil and industrial water meter Table 5. according to the direction of velocity water meter installation installation of water meters can be divided into horizontal and vertical installation of water meters. according to the installation directions are usually divided into horizontal and vertical installation of water meters installed meter (also known as vertical table), refers to the installation of its flow parallel or perpendicular to the horizontal plane of the water meter, the meter scale plate with "H" represents the horizontal installation, with the "V" represents the vertical installation. volumetric water meter can be installed in any position without affecting accuracy. 6 divided by the medium temperature of cold water and hot water. at medium temperature can be divided into cold water and hot water, the water temperature is 30 ℃ and the boundary (a) cold water: medium limit temperature is 0 ℃, the maximum temperature of 30 ℃ water meter. (2) hot water: Lower medium temperature is 30 ℃, maximum is 90 ℃ or 130 ℃ or 180 ℃ water meter. requirements of each country has slightly different, in some countries up to 50 degrees Celsius water table limit. 7 Press media pressure points are divided into ordinary water and high pressure meter according to the pressure used can be divided into ordinary water and high-pressure water meter in China, ordinary water meter nominal pressure in general are 1MPa. pressure meter is the maximum working pressure exceeds 1MPa types of water, mainly for underground oil through the pipeline water and other industrial water measurements.
