Urumqi ic card water meter price // quotation The development prospects of stepped intelligent IC card water meters
In China, due to the vast territory, large population, and uneven development in various regions. Overall, the vast majority of users in China still use traditional metering devices with low management efficiency and relatively backward technology. Only remote water meters are used in residential communities in economically developed large cities. For many small and medium-sized cities and counties in China, due to the incomplete infrastructure of their computer and information technology, the application of card-type pre-paid water meters is more practical for a long period of time. For economically developed large and medium-sized cities, their computer and information technology infrastructure is relatively good, and people have a relatively strong awareness of water resource protection and conscientious payment, and they have put forward high-quality requirements for water consumption methods. But overall, the application of intelligent water meters in China is still in its infancy.
