Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

As shown in fig. 7, 8, 9 and 10, a novel anti-electromagnetic interference mounting structure for an ultrasonic metering module includes: upper cover 2, ultrasonic wave metering module 3, fixed clamp 4 and casing 5.

The ultrasonic metering module 3 is arranged in the shell 5 and is in limit fit with the fixed hoop 4 through a limit structure matched with the fixed hoop 4, and the upper cover is arranged above the ultrasonic metering module 3 through the fixed hoop 4; casing 5 and upper cover 2 all adopt the metal material, and casing 5 and upper cover 2 are fixed through set screw 1 locking, and upper cover 2 laminates with casing 5 completely. The two sides 4-b of the lower end of the fixed hoop 4 are attached to the two sides 3-a of the ultrasonic metering module 3 to achieve the effect of limiting and fixing; the two buckles 4-a at the two sides of the upper end of the fixed hoop 4 are fixed with the grooves 2-a at the two sides of the upper cover 2 in a buckling mode. The shell 5 is provided with a groove matched with the two buckles at the two sides of the upper end of the fixed hoop 4.

Further, the upper cover and the shell are preferably made of copper, aluminum or stainless steel.

Furthermore, the upper cover and the shell are made of plastic materials, and the surface of the upper cover and the surface of the shell are covered with a layer of metal film.

The assembly process is as follows:

firstly, placing the upper cover 2 above the ultrasonic metering module 3; then the fixed hoop 4 is sleeved into the ultrasonic metering module 3, so that the two sides 4-b of the lower end of the fixed hoop 4 are attached to the two sides 3-a of the ultrasonic metering module 3 to achieve the effect of limiting and fixing; two buckles 4-a above the fixed hoop 4 are fixed with grooves 2-a at two sides of the upper cover 2 in a buckle mode; the 2-b position of the upper cover 2 and the 5-a position of the shell 5 are locked and fixed through the fixing screws 1, so that the assembly is stable and free from shaking.

Thereby the effect that reaches the switch-on of

upper cover

2 and 5 full laminating of casing forms a parcel ultrasonic wave metering module 3's shield cover, can reach anti-electromagnetic interference's effect.

The installation structure of the ultrasonic metering module (see fig. 1, 2, 3 and 4) used in the market currently is that after the raw materials are assembled together, the ultrasonic metering module and the channel cover are fixed by buckling at the positions P1 and P2.
