With the continuous progress of society, traditional water meters in more and more countries are replaced by ultrasonic waves. Ultrasonic water meters are the latest and most advanced technology for measuring water flow in pipelines.

The large water supply area, low data reading accuracy, long problem detection cycles, untraceable historical information and high management costs have led to high supply and sales and operating costs for water companies.

GPRS (General Packet Radio Service) water meters have become increasingly popular in recent years as a result of the need for efficient and accurate water management.

With the development of economy and society, people's houses become more and more intelligent. However, traditional water meters have the disadvantages of difficult monitoring, high cost and poor stability. The emergence of NB-IoT intelligent water meters will solve the above problems.

In recent years, with the development of science and technology, great changes have taken place in all walks of life. This also includes the water meter industry. The traditional mechanical water meter has gradually faded out of people's vision and replaced by the remote water meter.

In recent years, the Internet of Things technology has developed rapidly, promoting the life of the public and improving efficiency. Compared with the previous manual meter reading system, the remote prepaid water meter has obvious advantages.

In order to carry out more accurate and intelligent water supply management, ultrasonic water meters have been used in urban water supply pipelines, household water consumption master meters, water resource water intake monitoring, farmland irrigation and other places

With the change of energy structure, remote water meters have already entered thousands of households.

Water is the most important and overused natural resource in the world. According to a report of the World Resources Institute, about 17 countries, with a quarter of the world's population, are facing extremely high pressure on water resources.

IC card prepaid water meter is a kind of intelligent water meter that can automatically transmit data and settle transactions.
