First, when the half of the small inner inner shell is welded along the weld in a state in which ½ of the small inner inner shell is in contact with each other, one lower inner shell is formed. A sieve is formed, and when the half of the lower outer shell is formed to be slightly larger in size, the lower outer outer shell is formed by facing each other on both sides of the lower inner shell, and the lower outer shell is formed in duplicate. ¼ shape of the lower outer body is formed in a press die, such as a state in which the lower outer body is formed, or only the inlet and outlet of the lower outer body are incised, and two pieces having different sizes are formed first. Expand and separate the quarter-shaped separating part of the lower outer shell body, separate the press mold located inside, and contact the separating part again. When the weld is formed, the inner inner shell of the small water meter is completed. The lower part is made of ¼ shape of the small outer shell body, after the mold has been separated by expanding and separating the ¼-shaped separating portion of the lower outer shell body, which is slightly larger in size, and has a separation portion formed above the inlet and the outlet port. When the inner outer shell is inserted from above and the welded portion is formed by contacting the ¼-shaped separator of the slightly larger outer shell, the lower outer shell of the water meter is formed, and the lower outer shell of the water meter is formed in duplicate, Between the inner shell and the lower outer shell is characterized in that consisting of a lower outer shell configured to form an air layer, a vacuum or a heat insulating material.
