After the water passes through the second meter 40, the water flows back to the water tank 10 through the fourth tube body 80 to form a water circulation loop. One of the first meter 30 and the second meter 40 is a flow meter, and the other is a water meter. In this process, the user can observe the indications of the flow meter and the water meter. By comparing the indications of the flow meter and the water meter, the performance of the water meter with the flow meter as the reference standard can be obtained. Compared with the prior art, the intuitiveness of the water meter performance display is improved, and the problem of poor intuitiveness of the water meter performance display in the prior art due to the user's difficulty in obtaining the performance of the water meter by observing the working state of the water meter is solved.

[0074] Finally, it should be noted that, in this article, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "includes" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or terminal device that includes a series of elements includes not only those elements, but also other elements that are not explicitly listed, or also includes elements that are inherent to such process, method, article or terminal device.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0076] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
