Embodiment Construction

[0017] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0018] The water meter of the present invention can be obtained by refitting a mechanical water meter on-line. The mechanical water meter used online can remove its watch core, leaving only the base meter 1 connected in the pipeline. Such as figure 1 As shown, a casing is installed on the outside of the base watch 1, and a sensor assembly 3 and a display assembly 4 are arranged in the casing. Wherein, the data output terminal of the sensor component is connected with the data input terminal of the display component for data transmission, and the collected data is processed by the processor in the display component and displayed on the monitor, realizing the functio...

Abstract

The invention relates to a water meter. The water meter comprises a base meter, wherein an impeller shaft assembly is arranged in the base meter, wherein the a magnetic ring is arranged on one end of the impeller shaft assembly and extends out of the casing of the base meter; a shell is arranged on the base meter, and a sensor assembly and a display assembly are arranged in the shell; the data output end of the sensor assembly is connected with the data input end of the display assembly to achieve data transmission; and a magnetic ring in the sensor assembly is in coupling connection with the magnetic ring of the impeller shaft assembly through magnetic force. The water meter provided by the invention can be used for achieving the online modification of a digital water meter from a mechanical water meter, and displaying the instantaneous flow rate so as to check whether the type of the selected water meter is accurate or not in real time.

Description

technical field [0001] The invention relates to a water meter, in particular to a water meter which can convert a mechanical water meter into an electronic water meter online. Background technique [0002] The mechanical water meters currently in use have the following defects: a) It is impossible to solve the resistance caused by gear transmission friction to affect the initial flow performance of the water meter; c) dismantling the counter will easily lead to water disputes; d) the transmission signal is an analog signal, which needs to be reprocessed before it can be used; e) there is no instantaneous flow display; f) it is impossible to verify the accuracy of the water meter selection in real time, etc. Contents of the invention [0003] The technical problem to be solved by the invention is to overcome the existing defects and provide a water meter. [0004] In order to solve the above technical problems, the present invention provides the following technical solutio...
