[0027] like Figure 1-4 This is a schematic diagram of the structure of a high-precision ultrasonic water meter according to a preferred embodiment of the present invention. In this embodiment, the high-precision ultrasonic water meter includes a base 1, a housing 2 fixedly connected to the top of the base 1 by screws, an installation cavity 11 is provided in the base 1, a water pipe 3 is installed in the middle of the installation cavity 11, and an ultrasonic metering device 4 is installed directly above the water pipe 3 in the installation cavity 11, and the ultrasonic metering device 4 is connected to the water pipe 3. Through the communication between the ultrasonic metering device 4 and the water pipe 3, the water flow in the water pipe 3 is measured by the ultrasonic metering device 4. A display device 5 is provided on the top of the ultrasonic metering device 4, and the display device 5 is electrically connected to the ultrasonic metering device 4. The display device 5 allows the user to observe the usage data more intuitively. An observation window 21 is provided on the top of the housing 2 opposite to the display device 5, and a cover plate 6 is rotatably connected to the top surface of the housing 2 opposite to the observation window 21. The cover plate 6 protects the display device 5.

[0028] In this embodiment, the ultrasonic metering device 4 includes an ultrasonic instrument 41 and a meter 42. The meter 42 is installed at the rear end of the ultrasonic instrument 41 and is connected to the interior of the ultrasonic instrument 41. The bottom of the ultrasonic instrument 41 is located at the front end and is connected to the front end of the top of the water pipe 3. The bottom of the meter 42 is connected to the rear end of the top of the water pipe 3. With this structural design, the ultrasonic instrument 41 filters the flowing water, and the meter 42 measures the flow rate of the flowing water. The measured data is fed back to the display device 5, which displays the usage data.

[0029] In this embodiment, mounting brackets 12 are fixedly connected to both sides of the water pipe 3 inside the mounting cavity 11. The top of the mounting brackets 12 is provided with mounting holes 15, and the bottom of the ultrasonic instrument 41 is fixedly connected with a connecting block 43.

With this structural design, since the guide block 14 is trapezoidal, the display device 5 is aligned with the guide block 14 through the guide groove 52 and pressed down. The lower part of the guide block 14 is wider than the upper part, which plays a role in limiting the position of the guide groove 52 and the guide block 14 at the connection position, avoiding the possibility of the display device 5 being pressed down too much.

[0031] In this embodiment, a fixing block 22 is fixedly connected to the top of the housing 2, and a rotating cavity 23 is provided in the fixing block 22.
