[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1

[0018] Please see Figure 1 As shown, the electromagnetic water meter converter structure described in this embodiment includes a wire outlet base (17) installed on the electromagnetic water meter sensor (18). The top of the wire outlet base (17) is fixedly connected to the lower housing (15) by an O-ring seal (16) and screws. The O-ring seal (16) plays a sealing role to prevent water vapor from entering from the connection between the lower housing and the wire outlet base. The seal is achieved by combining the screw fixing ring.

[0019] A stainless steel bracket (14) is welded to the inner side of the lower housing (15). The stainless steel bracket 14 provides support for the battery compartment 12 and the battery compartment shell 13. Welding ensures its firmness. The welding position of the stainless steel bracket 14 is tightly connected to the lower housing 15 to prevent moisture from entering. The battery compartment (12) is placed inside the battery compartment shell (13). The battery compartment (12) and the battery compartment shell (13) are fixed to the stainless steel bracket (14) by screws.

[0020] Furthermore, the cable outlet base (17) and the electromagnetic water meter sensor (18) are fixedly connected by welding. The welding connection ensures the firmness and sealing between the two, preventing water vapor from seeping in from the connection.

[0021] Furthermore, the lower housing (15) is filled with sealant, and the sealant filling height does not exceed the upper end face of the battery compartment outer shell (13). After the sealant cures, it fills the gap inside the lower housing, further enhancing the sealing performance, preventing moisture from entering, and ensuring that the sealant does not overflow the upper end face of the battery compartment outer shell, thus avoiding affecting the installation of subsequent components.

[0022] To further explain, the converter PCB circuit board (10) is fixed inside the converter housing (9) and its stability is ensured by screws or other fixing methods; the converter housing (9) and the double studs (11) are fixed to the battery compartment (12) by screws. The double studs (11) are used to connect the converter housing and the battery compartment, ensuring the firmness between the two, while preventing moisture from entering through the sealing design.

[0023] To further explain, the transparent glass (5) and the O-ring (4) are pressed together by the aluminum clamping ring (6) in a threaded manner, and fixed inside the upper cover (3). The internal state can be observed through the transparent glass (5), and the O-ring (4) and the aluminum clamping ring (6) are used to ensure sealing and stability.

[0024] To further explain, the watch cover (1) and the watch cover seat (2) are fixedly connected by a pin. The bottom of the watch cover seat 2 has a barb, which is fixedly connected to the upper cover (3) after being pressed. The upper cover (3) and the lower cover (15) are fixedly connected by O-rings (7, 8) and screws. The sealing rings are used to achieve a seal and prevent moisture from entering.

[0025] The assembly process and workflow of this utility model are as follows:

[0026] Specifically, in this embodiment, the cable outlet base (17) and the electromagnetic water meter sensor (18) are fixedly connected by welding; the lower housing (15) is fixedly connected to the cable outlet base (17) by screws via an O-ring seal (16); a stainless steel bracket (14) is welded to the inside of the lower housing (15); the battery compartment (12) is placed inside the battery compartment shell (13), and the battery compartment (12) and the battery compartment shell (13) are fixed to the stainless steel bracket (14) by screws; after the above assembly is completed, the inside of the lower housing is filled with sealant, and the sealant filling height does not exceed the upper end of the battery compartment shell (13). After the potting compound has cured, the converter PCB circuit board (10) is fixed inside the converter housing (9); the converter housing (9) and the double stud (11) are fixed to the battery compartment (12) by screws; the transparent glass (5) and the O-ring (4) are pressed by the aluminum clamping ring (6) in a threaded manner to fix them inside the upper cover (3); the upper cover (3) and the lower housing (15) are fixedly connected by screws through O-rings (7, 8); the watch cover (1) and the watch cover seat (2) are fixedly connected by pins, and the bottom of the watch cover seat (2) has barbs, which are pressed to fix the watch cover seat to the upper cover (3).

[0027] Once the electromagnetic water meter is fully installed, it operates primarily based on Faraday's law of electromagnetic induction. The conductor cuts magnetic field lines, inducing an electromotive force inside the conductor. This induced electromotive force then conducts current through the measuring tube. During this conduction process, the direction of current flow is kept perpendicular to the direction of the magnetic field. This working principle ensures the operation of the electromagnetic water meter.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.

[0029] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
