Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1, the present invention is a flow meter, comprising:

a circuit card 1 mounted on the upper surface of the housing 2 for transmitting signals to the count display;

the shell 2 is fixedly connected with the cover 6 and used as a main framework for installing a component foundation;

the filter shell 3 is arranged on the side surface of the shell 2 and is used for installing the filter screen 4;

a filter screen 4 installed in the filter housing 3 for filtering impurities in the fluid;

a filter cap 5 for covering the filter screen 4 in the filter housing 3 to form a filter body;

the gear is arranged on the shaft and used for rotating when fluid flows, so that the electromagnet is intersected with the circuit plug-in unit 1 to generate a signal;

the electromagnet is arranged on the gear and is used for meeting with the circuit plug-in 1 to generate a signal;

a shaft installed between the housing 2 and the cover 6 for fixing a position of the gear inside the housing 2;

and a cover 6 coupled to the housing 2 for sealing the housing 2.

Specifically, the gears comprise a first gear 10 and a second gear 11, the first gear 10 is connected with the second gear 11, and both the first gear 10 and the second gear 11 are installed in the shell 2; the shafts comprise a first shaft 9 and a second shaft 12, the first shaft 9 and the second shaft 12 are both arranged in the middle of the shell 2, a first gear 10 is arranged on the first shaft 9, and a second gear 11 is arranged on the second shaft 12; the electromagnets comprise a first electromagnet 7 and a second electromagnet 8, the first electromagnet 7 is mounted on a first gear 10, and the second electromagnet 8 is mounted on a second gear 11.
