A sealing ring 11 is arranged between the connecting pipe 4 and the rectangular pipe main body 13. A first convex plate 7 is fixedly connected to the outer side wall of the connecting pipe 4, and a first through hole 8 is penetrated through the side wall of the first convex plate 7. A second convex plate 15 is fixedly connected to the outer side wall of the rectangular pipe main body 13. The first convex plate 7 corresponds to the second convex plate 15, and a fastening bolt 16 is inserted through the side wall of the second convex plate 15. The rod portion of the fastening bolt 16 corresponds to and cooperates with the first through hole 8, and a sealing cover 17 is detachably arranged on the end face of the first convex plate 7.
[0022] One end of the flowmeter body 1 is fixedly connected with a first flange 2, and the other end of the flowmeter body 1 is fixedly connected with a second flange 3.
