Chongqing Waterproof Water Meter Price The price of Chongqing waterproof water meters will be replaced before the end of the year, keeping pace with the times and launching new products.

1. Dry battery power supply design effectively overcomes the issues of lithium battery failure and replacement difficulty.

a) Generally, card-inserting water meters use lithium batteries for power supply, which have issues of battery failure and replacement difficulty due to the nature of lithium batteries;

b) Standard AA battery design allows users to easily obtain them;

c) Easy and simple to replace, requiring no tools or professional knowledge;

d) A dry battery can last up to 6 years on a single use;

2. The valve automatically closes when the battery is dead or being replaced, effectively preventing water theft; when the battery is functional, inserting the card automatically opens the valve without affecting the user's water use.

3. Waterproof design for the card slot, the whole meter can achieve spray waterproofing, meaning that when water is sprayed on the outside of the meter (for no more than 2 hours), it does not affect the operation of the card-inserting water meter.

4. Pilot valve design is not affected by scale or water pressure, making it safer and more reliable.

Chongqing Waterproof Water Meter Price The card-inserting water meter has become a new favorite of water supply companies and property management companies in recent years, with sales increasing year by year. Our newly developed and marketed Huiyi brand card-inserting water meter has various shapes, diverse types, and anti-tampering features. Based on the brand name and characteristics, our proposed slogan is: Colorful Life, Thoughtful Care. Huiyi Water Meter, Measuring Every Drop!

1. Automatic charging: Prepaid mode and postpaid mode.

2. Prepaid mode: Water is purchased and then used: The initial available water volume of the water meter is zero and the valve is closed. Users go to the water selling point to open an account, purchase water, and receive a user card to insert into the corresponding water meter, which reads the available water volume from the card, then opens the valve for normal water supply. Once the available water volume in the water meter is exhausted, the valve closes, and users need to go to the water selling point to purchase water again, then insert the recharged user card back into the water meter, repeating the process.

3. Postpaid mode: Water is used first and then paid for: The initial available water volume of the water meter is zero and the valve is closed. The management department sets the maximum allowable water usage for the user, pre-charging the user card at account opening. Users insert the user card into the corresponding water meter, which reads the available water volume, then opens the valve for normal water supply. Once the available water volume is exhausted, the valve closes, and users need to go to the water selling point to pay. The water selling point recharges the user card again, repeating the process.

4. Card replacement and recovery transfer function: A Fujian water meter user card can only successfully complete a transaction with the corresponding water meter once per water purchase. If the card is lost, it can be replaced according to the software database management functionality, and the water volume will not be lost or duplicated. When the water meter needs to be replaced, insert the recovery transfer card into the meter to read the internal data, and once the new meter is installed, the old meter information will transfer to the new meter.

5. Automatic implementation of tiered water pricing: The water meter is equipped with a clock and can store 12 months of water usage. When the user card is inserted into the water meter, the meter will write each month's water usage into the user card. Each time the user purchases water, the system automatically reads the monthly water usage from the user card and calculates the excess water fee based on the tiered water pricing, which the user must pay when purchasing water.

6. Mechanical and electronic dual mode display: The horizontal rotor water meter retains the wheel and pointer display of mechanical water meters while adding a liquid crystal display. Even if the electronic part fails, the accumulated water usage can still be read from the mechanical wheel display.

7. Used to measure the total amount of cold water flowing through pipes, suitable for unidirectional water flow, not applicable for corrosive fluids.

Improving the management level of water supply departments to achieve the goals of saving natural resources and human resources.

Enhancing the profitability of water supply plants, preventing meter reading, prepaid usage, accelerating cash flow, controlling cost losses, and eliminating fee arrears.

8. Safe and reliable, using dynamic encryption to achieve "one meter one card, one meter multiple cards, one card multiple meters," ensuring secure settlement between public water parties.

Some citizens called our news hotline questioning: Can card-inserting water meters also incur water fees?

"Every time the water is cut off at home, I always take my card to the designated location to buy water. How could I owe water fees?" said Mr. Wang, a resident of the Xingqing District's Shuiyi Fang community. With the residents' doubts, a reporter visited the Yinchuan China Railway Water Supply Group Co., Ltd. for interviews. The director of the water supply department explained that there are cases of users owing water fees, with some even owing nearly a thousand yuan. The reporter saw in a statistical table that a certain resident in Yunhe Garden has not purchased water since July 2009, accumulating 400 tons of unpaid water but still able to use it normally. Why does this situation occur? She explained that the card-inserting water meter is an electromechanical meter, and the user's water meter must have malfunctioned, leading to the arrears. During the interview, Mr. Li, a resident of Yunhe Garden, visited the company to inquire about payment matters. The staff found that Mr. Li had not purchased water since November 2010, "overdrafting" 162 tons of water.

"The card-inserting water meter is equipped with a battery. If the battery power weakens or runs out, when the remaining water purchased in the card is down to 2 tons, the water meter's stop-water prompt function disappears, but it continues to supply water normally. Card-inserting water meters generally start to experience various faults after about six years," she explained. If the electronic part of the water meter malfunctions, the water usage will be calculated based on the base meter reading on the water meter dial. "Base meter reading is currently the most accurate measurement method, with an error of no more than 4%," the director said.

According to calculations by the South Office of China Railway Water Supply, among the 160,000 users in the area, several thousand users have malfunctioning card-inserting water meters. What should users with malfunctions do? She suggested that users with low water pressure could apply for a meter replacement. Users who are unwilling to replace their meters should not only check the LCD data but also learn to read the dial data and pay according to their water usage at the water supply marketing company. They can also prepay their water fees.

The Huiyi brand Chongqing waterproof water meter price has effectively solved the user's electric fault problem:

Contactless card-inserting

3. Note: Most countries internationally require the use of water meters that reach at least Class B measurement grade. In the domestic industry, there have also been cases where Class A measurement grade card-inserting cold water meters are eliminated for measuring cold water flow in pipelines while having automatic charging functionality. Chongqing waterproof water meter price is driven by market demand and powered by technological innovation, focusing on quality assurance at every stage of production and distribution, along with a comprehensive after-sales service system that spans major cities nationwide. The factory has achieved certain social and economic benefits through quality and good reputation, promoting further development of the enterprise.

Chongqing waterproof water meter price development goals:

Implement modern scientific water meter development strategies to create a comprehensive functional supplier brand.

2. The current domestic and international water meters are gradually developing in the following directions:

1. High measurement grade water meters.

2. Using high measurement grade water meters can allow the water meter to work across a larger flow range, including very small flow rates, fundamentally improving the sensitivity and measuring capacity of water meters. Piston-type (also known as volumetric) water meters generally reach Class C or D measurement grades, but have higher requirements for water quality.

Water meter expectations. In the proposed new international standards and recommendations for water meters, devices based on electromagnetic or electronic principles used for measuring water flow are also included within the scope of water meters.

4. Remote outdoor reading combined with computer property management water meters.

Remote reading water meters, centralized reading systems, and compatible secondary instruments are promising for development as they improve the reading methods of water meters, increase the level of information, digitization, and automation, reducing disturbances to users of water meters and security concerns. In some domestic areas, when implementing one-meter-per-household, this type of water meter has also been adopted.

5. Prepaid water meters.

Prepaid water meters are applicable under the management system of "paying first and using water later." In some areas of our country, collecting water fees is difficult, and water fee arrears are serious. The use of prepaid water meters has completely changed the method of meter reading and settling water usage, avoiding exacerbation of conflicts while also increasing the technical content of water meter products. Some water supply plants and property management companies welcome this product. Prepaid water meters can timely and reasonably collect water fees, reduce water fee losses, lighten labor intensity, and avoid inconvenience and insecurity caused to users by meter reading activities. Typical products include horizontal rotor water meters (card-inserting or inductive), TM card water meters, code exchange prepaid water meters, etc.

6. Anti-backflow meters or bidirectional metering water meters.

Chongqing waterproof water meter price has been upgraded again, ensuring shopping security and service systems.

-@Chongqing waterproof water meter price@-☆Chongqing waterproof water meter price@-☆ According to reports, starting July 1 of this year, Fujian card-inserting water meters will enforce new drinking water standards. The new standards align with international standards, achieving 106 indicators, and are basically on par with the strictest water quality standards—European Union water quality standards. However, this mandatory standard is merely on paper, as there are no substantial punitive measures, and local governments and water plants do not feel threatened. Since the issuance of the Chongqing waterproof water meter price new standards, local governments and water plants have made little progress in water treatment process modifications. The issue of water fee arrears remains severe. Arrears may lead to property management companies defaulting on fees. Thus, the management issues related to the increasing Chongqing waterproof water meter price are becoming more pronounced. Water fees are the economic lifeline of water supply companies, and only by improving the efficiency of fee collection can water companies have greater motivation and guarantee to contribute more to social water supply. Additionally, the adoption of Chongqing waterproof water meter price may achieve tiered water pricing (advocating water conservation) and precise measurement (preventing water theft), providing significant support for the business development and water usage efficiency of water supply companies.

(1) Velocity-type remote reading water meters are installed in closed pipelines, consisting of a moving element driven directly by the speed of water flow. Typical velocity-type remote reading water meters include rotor water meters and screw water meters. Rotor water meters can be further divided into single-stream and multi-stream types.

(2) Volumetric Chongqing waterproof water meter price is installed in pipelines, consisting of known volume chambers that are sequentially filled and discharged with fluid, driven by the fluid. These are also referred to as fixed discharge type Chongqing waterproof water meter price. Volumetric Chongqing waterproof water meter price generally adopts a piston-type structure.

2. By measurement grade, the measurement grade reflects the working flow range of Chongqing waterproof water meter price, especially the measuring performance at low flow rates. Generally, they are divided into Class A meters, Class B meters, Class C meters, and Class D meters, with their measuring performance meeting the corresponding requirements specified in the national standards. PS: Some European countries' large-diameter remote water meters (such as turbine Chongqing waterproof water meter price or compound Chongqing waterproof water meter price) have particularly wide working flow ranges (can exceed 200:1), and also mark segment error limits and label "B, C" grade symbols, but the specific meanings of these symbols, characteristic flow values, and their corresponding regulations in the international standard ISO4064 differ.

3. By nominal diameter, nominal diameters are usually divided into small-diameter water meters and large-diameter water meters. Water meters with a nominal diameter of 40mm and below are generally referred to as small-diameter water meters, while those with a nominal diameter of 50mm and above are referred to as large-diameter water meters. These two types of Chongqing waterproof water meter price are sometimes also called residential Chongqing waterproof water meter price and industrial Chongqing waterproof water meter price. This classification can also be differentiated by the connection method of the water meter casing; water meters with a nominal diameter of 40mm and below use threaded connections, while those of 50mm and above use flange connections.

4. By purpose, water meters are commonly divided into residential water meters and industrial water meters. Residential water meters refer only to remote water meters used for residential water billing, while other purposes fall under industrial water meters. Industrial water meters are generally large-diameter Chongqing waterproof water meter price.

5. By installation direction, water meters are usually divided into horizontal installation water meters and vertical installation water meters (also known as upright meters), indicating whether the flow direction is parallel or perpendicular to the horizontal plane during installation. On the dial of the Chongqing waterproof water meter price, "H" represents horizontal installation, and "V" represents vertical installation. Note: When the name of the Chongqing waterproof water meter price does not specify, it generally refers to horizontal installation water meters. Volumetric water meters have no specific requirements regarding horizontal or vertical installation. Some large-diameter Chongqing waterproof water meter price that have undergone dynamic balancing treatment in Europe can also be installed horizontally, vertically, or at an angle, but the measurement performance varies based on the installation method; for example, horizontal installation can achieve Class C, while vertical or angled installations would be downgraded.

6. By medium temperature, water meters can be classified into cold water Chongqing waterproof water meter price and hot water Chongqing waterproof water meter price, with 30°C as the dividing line.

☆-@Chongqing waterproof water meter price@-☆Chongqing waterproof water meter price@-☆(1) Cold water meters have a lower limit temperature of 0°C and an upper limit temperature of 30°C. (2) Hot water Chongqing waterproof water meter price has a lower limit temperature of 30°C and an upper limit of 90°C, 130°C, or 180°C. Note: Unless specified, Chongqing waterproof water meter price generally refers to cold water meters.

7. By medium pressure, water meters can be divided into ordinary water meters and high-pressure water meters. In our country, the nominal pressure of ordinary Chongqing waterproof water meter price is generally 1MPa. High-pressure Chongqing waterproof water meter price refers to all types of Chongqing waterproof water meter price with a working pressure exceeding 1MPa, mainly used for measuring water in flow pipelines in oil fields and other industrial uses. Note: Unless specified, the nominal pressure of Chongqing waterproof water meter price is generally 1MPa. In some European countries, the nominal pressure of remote water meters is 16bar (1.6MPa).

8. By whether the counter is submerged in water, water meters can be divided into wet-type Chongqing waterproof water meter price and dry-type remote water meters and liquid-sealed Fujian card-inserting water meters. The typical performance distinction lies in whether the glass of the Chongqing waterproof water meter price withstands water pressure and whether the mechanical sensor and counter are directly gear-linked or magnetically linked.
