The transformation of Nanchong water meters into smart meters is based on advanced microcomputer control technology and uses the Xingtai card as the information transmission medium, forming a high-tech electromechanical integration Xingtai instrument. It has dual functions of mechanical counting and electronic counting, featuring advanced design, high technical content, complete functions, accurate measurement, reliable performance, and small size. Xingtai water meter It has the advantages of intuitive display, beautiful appearance, convenient installation, and ease of use. Features of Nanchong water meter transformation into smart meter:           ⊙ Starting flow less than 2L/h.           ⊙ Anti-electric and magnetic attack technology: when subjected to strong electric or magnetic attacks from the outside, the water meter will automatically close the valve.           ⊙ Using non-contact Xingtai patented technology, data is transmitted wirelessly, solving the problems of waterproofing and anti-attack.           ⊙ Zero power consumption patented technology: operating current is 0μA, ensuring the internal battery lasts for over 8 years.           ⊙ Electric floating ball valve patented technology: features anti-seizing and anti-scaling characteristics, achieving low pressure loss, low wear, low power consumption, rust prevention, and blockage prevention. The factory briefly discusses the current development of water meters: The application status of the domestic transformation of Nanchong water meters into smart meters. The article introduces the development of new water meters in China and the development of water meters abroad, while also analyzing the factors influencing the direction of water meter development. It compares different water meters and discusses the pros and cons of various water meters, emphasizing that water meter renovation workers also need some theoretical and practical knowledge. Keywords: water meter, development, pros and cons, renovation 1. The history and trends of water meter development Water meters are among the simplest and most widely used flow measuring instruments, and they are also important legal metrology instruments. According to new international standards and recommendations, water meters are defined and categorized by their intended use, meaning any flow meter used to measure potable cold water in closed pipelines with cumulative flow display is classified as a water meter. This includes mechanical flow meters such as rotor water meters, screw-wing water meters, and piston water meters, as well as electronic or electromagnetic flow meters like electromagnetic flow meters and ultrasonic flow meters. Additionally, water meters with electronic devices are those that have added various auxiliary devices to mechanical water meters to meet management and control needs, such as various IC card water meters and electronic remote reading water meters. Overall, the concept of water meters has significantly expanded compared to the past.
