With the development of society, economy and population, water resources have become scarce natural resources, and water resources management has begun to emphasize controlling the excessive growth of social and economic water demand. Intelligent water management is an inevitable trend.

As the most widely used metering terminal, water meter has become an important part of smart water system. A water meter is an instrument for measuring water flow. This industry has existed for 100 years. Its products have gradually developed from the initial all-mechanical structure to the stage of coexistence of mechanical watches and intelligent water meters, and are developing to the stage of intelligent water meters with higher intelligence.

? In terms of market installation, the traditional ordinary mechanical water meter is still the "boss" in the water meter industry. The general working principle of mechanical water meter is: the pressure generated by running water drives the gears in the water meter to rotate, and the gears under the water meter display panel drive the pointer to rotate and count, so as to achieve the purpose of measuring water consumption. Because the price of mechanical water meter is generally very low, it can basically realize the counting function in measurement accuracy, so it is widely used.

Although the traditional mechanical water meter is cheap and durable, it is difficult to charge because of the labor intensity of on-site reading. After 2000, domestic manufacturers have successively developed prepaid ic card smart water meters, realizing the mainstream mode of "pay first, then use water". At that time, I was lucky enough to work in an instrument factory in northwest China. At that time, I should have a famous saying, "standing on the tuyere, pigs can fly." At that time, the water supply company did not monopolize the market, and the user unit card could choose the brand of water meter independently. This type of water meter has gained great market recognition in the market, and it is often in short supply, which leads to the birth of 1008.

? After the rapid differentiation of the domestic water meter market, some manufacturers are more forward-looking and upgrade their products, thus producing the concept of remote meter reading. In the past, the industry background was that the water supply company only copied the consumption of the total meter, but due to various reasons of metering errors of pipelines and water meters, residential users will bear additional losses, that is, the price of water charges has risen, water is a non-renewable resource, and the country is guided by accurate water metering and avoiding waste. A variety of policy orientations, such as one meter per household, meter reading to households and ladder water price, have been released one after another, which has promoted the arrival of the era of remote intelligent meter reading. Many domestic manufacturers have carried out technical research and development, resulting in a series of communication methods such as wired MBUS, wireless Lora and NBIOT.
