At present, the smart water meters manufactured in China can be divided into two categories: prepaid water meters and remote water meters. The common feature is that the sensors that measure the water flow still use ordinary water meters, and are installed through a dial pointer or a gear set at the water meter. The sensing component converts the mechanical readings of the raw water meter into electrical signal data, and then collects, transmits and stores them, and automatically or manually controls according to the requirements of the settlement transaction method. Because their base tables are speed water meters, they are classified as speed water meters according to the principle of water meters. They only improve the reading mode and indicating mechanism, and increase the prepaid and remote readings. The functions of the automatic meter reading system, while the metering mechanism, transmission mode or mechanical type, the accuracy (accuracy) level of the water meter is the same as that of the ordinary mechanical water meter.
The intelligent water meter applies high-tech electronic and information transmission technology to the manufacture of water meters, which has changed the traditional domestic meter reading and settlement methods to a considerable extent, and has improved the level of tap water metering in China. It is a technological advancement in tap water metering and charging; The promotion and application realized the management of “buy water first, then use water” and centralized meter reading, updated the concept of payment for water users, reduced the phenomenon of water fee arrears, meter reading, etc., and reduced the manpower of meter reading in the water supply department. Material resources; water fee can be recovered in advance, the operation staff is reduced in the later period, the management efficiency and the management level of the water division are improved; and the anti-theft performance is better than that of the ordinary water meter, which can fully realize the “prepaid”, “stepped water price” and “cumulative water volume”. "Features.
