摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method for a gas meter allowing a measuring tube to be reused without being discarded, the measuring tube giving a measured value of flow rate falling outside an allowable range for correction.
SOLUTION: As for arrangements of projecting and recessed shapes on straightening vanes 24 disposed at prescribed spaces, at least two arrangements are previously selected: a first arrangement effecting an increase in a correction coefficient and a second arrangement effecting a decrease in the correction coefficient. In assembling a gas meter, firstly, the gas meter is assembled by using the measuring tube 22 with the straightening vanes 24 assembled by an optional arrangement to find a correction coefficient with respect to a reference flow rate. Where the found correction coefficient falls outside the allowable range and is shifted to the larger value side, the measuring tube 22 is disassembled and the straightening vanes 24 are rearranged according to the second arrangement to reassemble the measuring tube 22. When the found correction coefficient falls outside the allowable range and is shifted to the smaller value side, the measuring tube 22 is disassembled and the straightening vanes 24 are rearranged according to the first arrangement to reassemble the measuring tube 22.

摘要： PROBLEM TO BE SOLVED: To maintain the weight of a gas meter and its manufacturing cost as in the past while reducing a measurement error in a flow volume.
SOLUTION: This gas meter 10, equipped with a buffer part 42a communicating with a flow path of gas and capable of storing water therein, comprises a bottom surface panel member 42 (fixing member) for fixing a measuring tube 40 between the buffer part 42a and a flow-path member 22. This structure increases the volume of water storable in this gas meter 10 by the volume of water stored in the buffer part 42a in addition to the volume of hitherto storable water. Since such a situation can be therefore decreased that water accumulated in large quantities overflows even into the measuring tube 40, the measurement error in the flow volume can be reduced. Further, since the buffer part 42a has the function of fixing the measuring tube 40 in conjunction with the flow-path member 22, the need for simply enlarging the gas meter 10 is dispensed with. The weight of the gas meter 10 and its manufacturing cost, therefore, can be maintained as in the past.

摘要翻译：要解决的问题：为了保持气体计量器的重量及其制造成本，同时减少流量的测量误差。解决方案：配备有与气体流路连通并能够在其中储存水的缓冲部分42a的燃气表10包括用于将测量管40固定在缓冲器之间的底面板构件42（固定构件）部分42a和流路构件22.该结构除了存储在缓冲部分42a中的水的量之外，还增加了该气体计10中可储存的水的体积。因此，由于大量积存的水甚至会溢出到测量管40中，因此能够减少流量的测量误差。此外，由于缓冲部分42a具有与流路部件22一起固定测量管40的功能，所以省去了简单地扩大燃气表10的需要。因此，能够像以往那样维持燃气表10的重量及其制造成本。版权所有（C）2009，JPO＆INPIT
