Problems solved by technology

[0002] The membrane gas meter includes a housing, and a reading display device is fixed on the front side of the upper cover of the housing. The reading display device is generally fixed in the installation groove on the front side of the upper cover by screws, and the screws are generally exposed. Gas meters are generally exposed in an open environment, so the screws are easily blocked by dust and rust, which is not conducive to subsequent maintenance operations

Abstract

The invention relates to a film type gas meter, comprising an upper cover. The upper cover comprises a body. The front side of the body is provided with an installing groove. The installing groove is internally provided with a reading display device. The periphery of the reading display device is provided with a raised edge used for assembling. The reading display device is connected with the installing groove through a corrosion resistant structure. The film type gas meter is simple in structure and convenient in use, and is low in production cost. The arrangement of the corrosion resistant structure isolates a screw from the external, and prevents dust blocking on the screw as much as possible, and more important is that corrosion of the screw is prevented as much as possible.

Description

technical field [0001] The invention relates to the technical field of gas meters, in particular to a membrane type gas meter. Background technique [0002] The membrane gas meter includes a casing, and a reading display device is fixed on the front side of the upper cover of the casing. The reading display device is generally fixed in the installation groove on the front side of the upper cover by screws. Gas meters are generally exposed to an open environment, so the screws are easily blocked by dust and rusted, which is not good for subsequent maintenance operations. SUMMARY OF THE INVENTION [0003] Aiming at the above problems existing in the prior art, the purpose of the present invention is to provide a membrane gas meter with a simple structure, convenient use, low production cost, and at the same time preventing corrosion of the screws used to fix the reading display device as much as possible. . [0004] In order to achieve the above purpose, the present invent...
