[0019] In conjunction with specific embodiments, the present invention will be further described. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope limited by the application.

[0020] like Figure 1-2As shown, an insertable ultrasonic flow meter protective cover is disclosed, and the device is suitable for outdoor use. Specifically, it includes a box body 1 with an opening on one side, and the opening is tightly combined with the outer wall of the pipe. A fixing device 2 for fixing the ultrasonic flow meter is arranged inside the box body 1, that is, the sensor threaded port of the ultrasonic flow meter is fixed in the box body 1 through the fixing device 2. An arc groove 3 is arranged at one end of the opening of the box body 1, and the ultrasonic flow meter is fixed inside the box body through the fixing device 2, which effectively prevents the ultrasonic flow meter from being damaged. The arc groove can be used to place a round pipe so that it fits tightly with the device.
