These data are transmitted to the dial assembly for comparative analysis, enabling the user to intuitively understand the actual filtering effect of the filter member. This not only improves the accuracy and timeliness of water quality monitoring, but also helps the user to discover possible performance degradation or clogging problems of the filter member in a timely manner, thereby taking appropriate measures for maintenance or replacement to ensure the continuous and efficient operation of the water meter and the safety and stability of the water quality.

The water-blocking interlayer (such as rubber) provided between the dial assembly 5 and the protrusion 4 / housing 1 further enhances the sealing performance of the water meter. The water-blocking interlayer can effectively block water flow penetration and prevent water overflow or penetration into the interior of the dial assembly 5, thereby protecting the electronic elements or mechanical structures inside the dial assembly 5 from moisture erosion and prolonging their service life. The material selection (such as rubber) of the water-blocking interlayer not only has good sealing performance, but also has certain elasticity and wear resistance, which helps to resist water flow impact and wear during long-term use, improves the durability and safety of the water meter.

[0028] Specifically, the water meter further comprises a cover 6 made of transparent material, which is used to display information on the dial assembly 5 while protecting the dial assembly 5, and a limiting piece 7 abuts against the cover 6 and then abuts against the dial assembly 5 through the cover 6 to limit the dial assembly 5. The use of the transparent cover 6 enables the user to clearly observe all information on the dial assembly 5 without opening the water meter shell to obtain real-time water flow data, thereby improving the convenience of use. Meanwhile, the cover 6 serves as an additional protective barrier to effectively prevent the dial assembly 5 from being physically damaged by external factors such as impact and scratching, and to prevent impurities such as dust and water vapor from entering the interior of the dial assembly 5, thereby prolonging the service life of the dial assembly 5 and ensuring the accuracy and reliability of the water meter.

This not only ensures that the water flow can be fully filtered to improve the filtering effect, but also effectively prevents unfiltered water from directly entering the water outlet channel to ensure the safety and stability of the output water quality. In addition, the separation of the chambers facilitates cleaning and maintenance of each part, especially the filter 10 in the second chamber 14, which can be more conveniently replaced or cleaned, thereby prolonging the service life of the water meter and ensuring its continuous and efficient filtering performance.

These data are transmitted to the dial assembly 5 for comparison and analysis, enabling the user to intuitively understand the actual filtering effect of the filter 10. This not only improves the accuracy and timeliness of water quality monitoring, but also helps the user to timely discover possible performance degradation or clogging problems of the filter 10, so that appropriate measures can be taken for maintenance or replacement, thereby ensuring the continuous and efficient operation of the water meter and the safety and stability of the water quality. In addition, this technical feature also enhances the intelligent level of the water meter and improves the user experience, making water quality management and water meter maintenance more convenient and efficient.
