[0008] As a preferred embodiment of the low-pressure-loss ultrasonic water meter measuring tube of this utility model, a set of connecting parts includes a convex connecting part and a concave connecting part, wherein the convex connecting part is embedded in the concave connecting part to achieve connection.

[0009] As a preferred embodiment of the low-pressure-loss ultrasonic water meter measuring tube of this utility model, the pipe hole formed by the first bracket and the second bracket is waist-shaped.

[0010] As a preferred embodiment of the low-pressure-loss ultrasonic water meter measuring tube of this utility model, the first bracket and the second bracket both exhibit an arc-shaped outward expansion from the center position to both ends.

[0011] As a preferred embodiment of the low-pressure-loss ultrasonic water meter measuring tube of this utility model, both ends of the first bracket and the second bracket are provided with a set of injection molding holes.

[0012] The beneficial effects of this utility model are as follows: This utility model provides a low-pressure-loss ultrasonic water meter measuring tube. The symmetrical design simplifies installation and greatly reduces the cost of mold making. At the same time, the compression of the waist-shaped measuring tube in this solution is greatly reduced, which solves the problems of existing ultrasonic measuring tubes, which are inconvenient to install and require segmented mold making, resulting in high costs. On the other hand, existing measuring tubes have large pressure loss and cannot run at high current during testing and verification. Attached Figure Description
