The water meter industry is constantly evolving and upgrading. Wireless remote water meters are the future trend.
Under the joint promotion of smart water and ladder water, China's water meters have evolved from non-intelligent mechanical watches to smart cards for IC cards and photoelectric direct-reading smart meters. They have become the main products in the market, and they have finally transitioned to wireless remote water meters. Mechanical watches For residential communities with a certain scale, residents are scattered in different units, and it is more troublesome to check meters and collect fees at home. The IC card prepayment intelligent water meter has enabled the modern "first payment, after-used water" new management model to realize the electronic and intelligent water fee management. Photoelectric direct-reading water meter uses photoelectric direct reading technology to read character wheel data. Compared with traditional pulse meter, it can reduce reading error to zero, and usually does not need power supply. It only needs to supply power to meter or valve only when it is used. The wireless smart water meter system is a new and advanced meter reading method that incorporates today's most advanced computer and communication technologies. In the current industry and daily life, short-range wireless communication technologies mainly include Wi-Fi, Bluetooth, infrared, UWB, ZigBee, etc. The common disadvantage is that the transmission distance is short, which limits its wider application. Faced with rapid growth in the scale of physical and object connectivity, low-power wide area networks dedicated to the Internet of Things have multiple technical standards, and LoRa, Sigfox and NB-IOT have come to the fore.
The layout of smart water meters at home and abroad for many years, the future market is huge.
With the increasing shortage of water in the world, smart water meters are widely used to reduce water waste, improve management efficiency and save labor costs. The main market for this technology is concentrated in developed regions such as North America and Europe. In developing regions, the application of smart metering equipment is generally still in the pilot phase. In the domestic market, stepped water and smart water services will jointly promote the growth of smart water meters. The future of smart metering industry is expected to turn to oligopolistic competition, and large-scale water meter companies are expected to emerge from the market and continue to enjoy a high degree of prosperity in the industry. The global smart meter market has grown steadily in recent years. The total market size in 2012 exceeded 3 billion U.S. dollars, and it is expected to maintain a compound annual growth rate of more than 10% in five years, and to achieve a total revenue of over 5 billion U.S. dollars in 2017, according to the current situation in China. The smart meter is calculated by about 350 million urban users, and the potential market capacity may reach 100 billion yuan.

[China Instrument Network Instrument Industry] At present, China's water meter intelligence rate is not high, 90% of the current water meter or manual meter reading, manual meter reading has many drawbacks. According to the forecast of Forrester, a US research institute, the industrial value brought by the Internet of Things will be 30 times larger than that of the Internet, and the Internet of Things will become the next trillion-level information industry business. Under the Internet of Things technology, smart meters depend on the current era of rapid development of technology. Intelligent water meters and systems have unparalleled advantages over traditional water meters, and are mainly reflected in the following aspects: (1) remote control; 2) Water price measurement; (3) Electronic billing; (4) Data platform; (5) Flexible management; (6) Abnormal consumption analysis; (7) Commissioned hosting. At the same time, national policies and the government implemented smart water and ladder water, and smart water meters ushered in new development momentum. In order to implement the step-rate water price policy, accurate measurement, accurate timing, and accurate billing for the scientific mechanism of the water price ladder, the reasonable collection of water fees for each water segment is the key to implementing the ladder water price mechanism, and it needs the support of smart water meters.
