Focusing on intelligent water meters - Jingda escorts the implementation of tiered water prices
Source:      Release time:2014/03/25

Preface: With the gradual implementation of the national tiered water price policy, the implementation of tiered water prices in various cities has been carried out in full swing. The large-scale implementation of tiered water prices will become an important booster to promote the rapid development and growth of the intelligent water-saving water meter industry. The widespread application of intelligent water meters will undoubtedly usher in a historic development opportunity. As an active responder to the implementation of tiered water prices, as an innovator and pioneer in the field of intelligent water meters, Jingda Company has deeply analyzed the problems and difficulties in the operation of this policy, and put forward reasonable product selection solutions for reference by relevant departments.


[Background]


In January 2013, the National Development and Reform Commission and the Ministry of Housing and Urban-Rural Development issued the "Guiding Opinions on Accelerating the Establishment and Improvement of the Urban Resident Water Use Tiered Price System", deploying the comprehensive implementation of the urban residents' tiered water price system and accelerating the establishment and improvement of the urban residents' tiered water price system. The Guiding Opinions clearly stated that the establishment and improvement of the tiered water price system for residents should be based on the premise of ensuring the basic living water needs of residents, and the reform of the water pricing method for residents should be used as a starting point. Through measures such as improving the system, implementing responsibilities, increasing investment, and improving guarantees, the regulatory role of the tiered price mechanism should be fully utilized to promote water conservation and improve the efficiency of water resource utilization. The Guiding Opinions also made it clear that: before the end of 2015, cities with municipal status should, in principle, fully implement the tiered water price system for residents; towns with the conditions for implementation should also actively promote it. Among them, the core content of "establishing and improving the main content of the tiered water price system for residents" was elaborated respectively: "determination of water volume for each tier", "metering and payment cycle", and "accelerating the implementation of the transformation of 'one household, one meter' in cities". This undoubtedly puts forward higher requirements for the intelligent, efficient and intensive management of tiered water use.


As we all know, the gradual application of smart water meters, especially remote water meters, has made water companies and other users feel the charm of intelligent products. It not only has many excellent performances such as high sensitivity, accurate measurement, error correction, and low power consumption, but also has reached a new level in management methods and efficiency, fundamentally changing the traditional meter reading method. On the basis of saving a lot of manpower, it directly brings significant economic and social benefits to the water supply industry. With the country's high attention to water resources; with the gradual advancement of the tiered water price policy; with the gradual trend of water company management towards modernization, efficiency, and intensiveness; with the continuous improvement of building and residential conditions, the people's requirements for the intelligence, safety, comfort, and privacy of residential facilities are increasing. The intelligence of residential and urban areas will also be the direction of future urban development. For this reason, the Ministry of Construction has put forward the requirement of "three meters out of the house" for the well-off housing standard, that is, it requires the reform of the traditional manual door-to-door meter reading method. Therefore, the popularization of intelligent water meters is imperative and will become an inevitable choice for future water meter upgrades.


【Product Upgrade is the Only Way】


Currently, urban water supply enterprises across the country are vigorously promoting the "one meter per household, meter reading at home" work, gradually changing the backward meter reading and charging methods in the past. The tiered water price requires that the water meter can transmit data remotely, read meters in a large area, and read meters in real time and regularly, so that the water company can collect the water consumption of each household in a timely and accurate manner. The implementation of "one meter per household, meter reading at home" in urban water supply enterprises will involve changes in meter reading, settlement, service and other modes and requirements for meter reading employees, which will affect all aspects of enterprise management; it requires a large amount of capital investment, and the source of funds is diversified; this work is related to the vital interests of thousands of households, and is highly policy-oriented. At the same time, the housing and pipe network conditions are complex, and the complexity of construction promotion is very high. To promote this work, a plan that is both economically feasible, technologically advanced and sustainable must be selected.


Currently, there are four options available for water supply enterprises to choose from, namely: meter readers reading meters at home; meters reading at home; prepaid water meters; remote water meters. Let's first analyze the pros and cons and feasibility of the four solutions:


Meter reading method

Advantages

Disadvantages

 

Home meter reading

Ordinary water meters are still used, and meter readers go to households to read meters. The advantages of this method are that it is simple and easy to operate, and the one-time equipment investment is small.

A large number of meter readers are needed, which results in huge manpower consumption, is not conducive to the need to reduce staff and increase efficiency, and it is also difficult to take the management of meter readers to a new level.

 

Meter out of the house

This solution facilitates meter reading and maintenance, but the renovation cost is high and it is only suitable for newly built multi-story residential buildings.

Renovation of old residential buildings is too difficult and expensive. Especially in the cold north, water meter wells below the frozen layer must be set up. The one-time investment in laying pipes, antifreeze and digging water meter wells is huge, and the maintenance cost is also high. It is very difficult to implement metering at home in the north, and it is not applicable to high-rise residents.

 

 

 

Prepaid water meter

The technology is mature and has the feature of prepayment, which enables "buy water first, use water later". It does not require meter reading, will not cause arrears, and reduces the manpower, material resources and subsequent operating personnel of water supply companies for meter reading. The anti-theft performance is better than that of ordinary water meters. It can realize the functions of "tiered water price" and "water storage".

Since stored-value cards are prepaid and do not require meter reading, it is impossible to count and evaluate the water company's monthly water consumption, pipe network leakage and other data; the cost is high, and the cost of periodic calibration, maintenance and replacement is high.

 

 

Remote water meter

It can monitor the operation of water meters in real time, is convenient and efficient to manage, and has complete functions and is easy to install. It is the best model for the future.

 

The cost is about one-third higher than that of IC card water meters. In addition, the technology of most enterprises is not mature yet, the anti-interference ability is poor, and the operation is unstable. At present, many enterprises do not have the conditions for large-scale promotion.

 

From the perspective of the reality, feasibility and long-term management of the above four solutions, remote water meters and prepaid water meters are better choices for the implementation of the tiered water price policy, especially remote water meters, which are bound to become the mainstream products for the implementation of the tiered water price policy due to their extensive functions, modern and efficient management. Because the above two types of smart water meters are suitable for charging occasions with different charging prices according to the user's monthly water consumption. Two water volume demarcation points and three charging water prices can be set. When the user's monthly water consumption does not exceed the demarcation point, the water fee can be charged at the normal water price. When it exceeds the demarcation point 1, the water fee can be charged at a higher water price. When the monthly water consumption exceeds the demarcation point 2, the water fee can be charged at a higher water price, thereby reasonably limiting the user's water consumption, achieving the purpose of saving water and avoiding waste of water resources. It is also the preferred metering and charging tool for the modern management of the tap water charging department. From this point of view, product upgrades are the only way to implement tiered water prices. As the key to the implementation of tiered water prices, tiered water meters provide a "evidence-based" standard for tiered water prices from the perspective of measurement, which will surely greatly accelerate the promotion of tiered water prices.


[Payment cycle is worth exploring]


The "Guiding Opinions on Accelerating the Establishment and Improvement of the Tiered Water Price System for Urban Residents" puts forward guiding opinions on the "metering payment cycle", namely: "Seasonal water use differences should be considered, and the metering payment cycle should be monthly, quarterly or annual..." In specific practice, if the metering payment cycle is annual, it is not conducive to the true realization of tiered water prices. There are two reasons. First, the cycle is too long, and the people are not very concerned about the use of water prices and gradient changes. Second, the water price is relatively low, and most people are not very sensitive to water prices. It is difficult for users to actively save awareness, which makes it difficult to achieve the purpose of tiered water prices to save water. If the metering payment cycle is monthly or quarterly, if the traditional mechanical meter is still used, it will undoubtedly increase the workload of meter reading and reduce work efficiency. In this case, smart water meters, especially remote water meters, play a positive role. Its real-time monitoring, accurate measurement, flexible payment methods and other functions can not only provide users with water usage at any time, but also help water companies to minimize the unnecessary loss of water caused by large measurement errors. It has played a two-way effect of saving water and efficient water use, and can also allow end users to change their water use in real time and improve water conservation awareness.


Although there are still many users in the market who are skeptical and cautious about the stability and anti-magnetism of remote meters, Jingda, which has a long history of development in the field of smart meters, has greatly reduced the risks of these products, and the product performance has reached the international leading level. Jingda remote meters are further divided into wired remote meters, vertical remote meters, photoelectric direct reading, and large-caliber remote lights. The data concentrators are wired remote transmission and wireless remote transmission. The products have small starting flow, high measurement accuracy, automatic error repair function, low energy consumption design, and some products also use PPO environmentally friendly energy-saving materials, which are in line with the product development concept of health and environmental protection. These products have been widely used throughout the country. Many subordinate units of PetroChina and water companies, universities and well-known hospitals in many cities across the country have used the Jingda remote meter reading system, which has achieved good results, won wide reputation from customers and played an important role in reducing water peaks and filling valleys. Therefore, from the perspective of water-saving effects, the shorter the meter reading cycle, the more conducive it is to highlighting the water-saving effect and forming water-saving awareness.


[Product escort, quality first]


As the saying goes: Opportunities always come to those who are prepared. Fools miss opportunities, wise men seize opportunities, successful people create opportunities, and opportunities are only for those who are prepared. The role played by smart water meters in the implementation of the tiered water price policy is unquestionable, but the requirements for product quality have risen to a considerable height. Hangzhou Jingda Electronics Co., Ltd.
