Ordinary mechanical water meters, that is, the common water meters used in our previous home. The basic working principle is to use the pressure generated by the flow of tap water to drive the rotation of the internal gear of the water meter, and the gear under the water meter display plate to drive the rotation of the pointer to count, so as to achieve the purpose of measuring water consumption, because the price is very low, can also achieve the role of counting, so the scope of use is very wide. But ordinary mechanical water meters are mostly indoor. When water management departments want to read meters for users, it is difficult for users to ensure that they are at home, so they will increase the workload of meter-reading staff to run back and forth many times, because it is manual meter-reading, and it is easy to charge less, more or even no fees. Fees and other phenomena, and if the water meter is put outdoors, management is relatively convenient, but the accompanying problems also follow. First of all, because many water meters are copper, there will be many illegal people smuggling watches to sell at night; and the low temperature in winter will cause a large number of water leakage, causing losses to water companies. There is also a mechanical watch wear larger, it is easy to forbid or break down.

 

At this time, due to various problems of ordinary mechanical water meters, the water meter industry has changed, and intelligent water meters have emerged. There are many kinds of intelligent water meters. Such as: photoelectric remote water meter, IC card prepaid water meter, ultrasonic water meter, electromagnetic water meter, wireless remote water meter, Internet of Things water meter and so on. First of all, the most prominent point of intelligent water meter is that it can transmit the data on the water meter remotely, unify the management, save a lot of manpower and material resources to read the meter, and basically will not make mistakes. There is also the realization of remote switching valves, but also timely detection of abnormal pipeline water flow and other advantages. And the precision of intelligent water meter is higher than that of ordinary mechanical water meter. The ultrasonic water meter is a typical representative. Most of the ultrasonic water meters on the market can reach the second level of accuracy, while the mechanical water meter can only reach the third level of accuracy at most. In addition, most intelligent water meters are made of copper base meters, while mechanical water meters are made of cast iron.

 

Thus, in the near future, mechanical water meters will gradually disappear in the public's sight, replaced by intelligent water meters, which will be households. Really record all the water use information of each household, and realize the real wisdom of water!
