In addition, telescopic joints can be arranged on the first branch pipeline 4 and the second branch pipeline 5, and rails are arranged at the bottom ends of the first weighing container 1 and the second weighing container 2, so that the distance between the first weighing container 1 and the second weighing container 2 and the inclined tee joint 6 can be adjusted at any time, the path of an additional pipeline is shortened, and the uncertainty of a subsequent gas weighing result is further reduced.
In order to further reduce the mass change of the gas in the additional pipeline and reduce the uncertainty of the weighing result, the first main pipeline 3 and the first branch pipeline 4 are connected to form a first included angle which is 100-170 degrees (such as 120 degrees, 127.5 degrees, 150 degrees and the like). The first main pipeline 3 and the second branch pipeline 5 form a second included angle after being connected, and the second included angle is 100-170 degrees (such as 120 degrees, 127.5 degrees, 150 degrees and the like).
