When the main connection portion 310 is an incomplete circular tubular structure, the radial cross section of the main connection portion 310 is preferably a major arc, that is, the circumferential length of the main connection portion 310 is greater than the semicircular length, so that the main connection portion 310 can be stably sleeved on the main pipe 100 and is not easy to loosen.

In one possible embodiment, the radial cross-section of the primary connecting portion 310 is circular or a major arc.
Illustratively, when the number of the primary connecting portions 310 is one, the primary connecting portions 310 may be a complete circular tubular structure, or may be an incomplete circular tubular structure. When the main connection portion 310 is a complete round tubular structure, it may completely wrap the side of the main pipe 100 in the circumferential direction to maximize the connection stability of the two. When the main connection portion 310 is an incomplete circular tubular structure, the radial cross section of the main connection portion 310 is preferably an arc, that is, the circumferential length of the main connection portion 310 is greater than the semicircular length, so that the main connection portion 310 can be stably sleeved on the main pipe 100 and is not easy to loosen.
In the embodiment of the present invention, in order to further improve the connection stability of the main connection part 310 and the main pipe 100, an adhesive may be used to fill a gap between the main connection part 310 and the main pipe 100, or an inner surface of the main connection part 310 and/or an outer surface of the main pipe 100 may be provided as a rough surface to increase a frictional force therebetween.
In one possible embodiment, the radial cross-section of the part-coupling portion 320 is circular or major arc.
For example, when the number of the main connection parts 310 is one, the sub-connection parts 320 may have a complete circular tubular structure, or may have an incomplete circular tubular structure. When the connecting portion 320 is a complete round tubular structure, it can completely wrap the side of the measuring tube 200 in the circumferential direction to maximize the stability of the connection between the two. When the sub-connection portion 320 is an incomplete circular tubular structure, the radial cross section of the sub-connection portion is preferably a major arc, that is, the circumferential length of the sub-connection portion 320 is greater than the semicircular length, so that the sub-connection portion 320 can be stably sleeved on the measurement pipe 200 and is not easy to loosen.
In the embodiment of the present invention, in order to further improve the connection stability of the portion connection portion 320 and the measurement pipe 200, an adhesive may be used to fill a gap between the portion connection portion 320 and the measurement pipe 200, or the inner surface of the portion connection portion 320 and/or the outer surface of the measurement pipe 200 may be provided as a rough surface to increase the frictional force therebetween.
In a possible embodiment, the coefficient of thermal expansion of the material used for the support 300 is less than or equal to the coefficient of thermal expansion of the material used for the main duct 100; while the coefficient of thermal expansion of the material used for the support 300 is also less than or equal to the coefficient of thermal expansion of the material used for the measurement tube 200.
Illustratively, since there may be a large temperature difference between the fluid flowing through the main pipe 100 and the fluid flowing through the measuring pipe 200, the main pipe 100 and the measuring pipe 200 may have a large volume change due to the temperature change, resulting in an increased gap between the support 300 and the support 300, and reducing the connection stability between the support 300 and the main pipe 100 and the measuring pipe 200. In an embodiment of the present invention, the supporting member 300 may be made of a material with a small Coefficient of Thermal Expansion (CTE), such as a composite material, so that the volume change caused by the temperature change is as small as possible, and the gap change between the supporting member 300 and the main pipe 100 and the measuring pipe 200 caused by the temperature change is reduced, thereby improving the connection stability.
In the embodiment of the present invention, in addition to the above requirement for the thermal expansion coefficient, the support 300 is required to have a large rigidity. Preferably, the rigidity of the support 300 should be greater than the rigidity of the main pipe 100 and the measurement pipe 200, so that the support 300 can stably endure vibration for a long period of time without adversely affecting the connection state when the measurement pipe 200 vibrates.

Therefore, it is intended that the appended claims be interpreted as including preferred embodiments and all such alterations and modifications as fall within the scope of the invention.
