[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1 to 2 , the present utility model provides a technical solution: an electromagnetic water meter converter with a simple structure, including an upper cover 1 and a base 2. The upper cover 1 and the base 2 are connected by screws. A flowmeter body 3 is provided on one side of the upper cover 1, and an observation window 4 is provided in the middle of the upper cover 1. A glass plate 5 is provided in the observation window 4. A sealing ring 51 is provided between the upper side of the glass plate 5 and the upper cover 1. The sealing ring 51 prevents water from entering the upper cover 1 through the observation window 4. A mounting plate 52 is provided on the lower side of the glass plate 5. The glass plate 5 is fixed in the observation window 5 through the mounting plate 52. The mounting plate 52 is threadedly connected to the upper cover 1. A battery compartment 6 is provided in the base 2, and a battery 7 is provided in the battery compartment 6. There are a total of 8 batteries 7, and alkaline dry batteries are used. A large circuit board 8 and a small circuit board 9 are provided at the upper end of the battery compartment 6, and a capacitor 10 is provided in the battery compartment 6. The capacitor 10 is electrically connected to the large circuit board 8 and the small circuit board 9. The battery 7 supplies power to the large circuit board 8 and the small circuit board 9.
