摘要： PURPOSE:To provide a fluidic flowmeter where a shut-off valve for a large volume type flowmeter can be commonly installed whichever the flowmeter is a large volume type one or a small volume type one so that the identical type shut-off valves are suitable for mass-production. CONSTITUTION:A partition 27 is provided in a passage body 23 forming a passage 26 to divide it into an upstream side passage 28 and a downstream side passage. In a large flow rate type flowmeter, the partition 27 is widened and in a small flow rate type flowmeter, the partition 27 is narrowed. One of the side of the passage 26 in the width direction is closed with the passage body 23 and the other side is closed with a cover plate 50 so that the width of the passage is formed to be fitted to the range of flow rate and types of a shut-off valve 18 are unified to the one for the large flow rate type flowmeter. In the small range of flow rate type flowmeter, the cover plate 50 is so constituted that the width of the passage gradually become narrower from a side of a partition 22 to a downstream side of the passage 26 to be arc-shaped.

摘要： PROBLEM TO BE SOLVED: To provide a support metal fitting for gas meter than can conserve a piping joint at least at the same level as a case for supporting a conventional compact and light gas meter. SOLUTION: The support metal fitting 1 has, for example, a hook part 18 that is gear-locked to a gas pipe 4 and a support part 19 for supporting the gas meter body 5 for a load that is vertical to the flow of a gas flowing in the gas pipe 4. The hook part 18 is formed in a hook shape with an arc along the outer periphery of the gas pipe 4 and is provided so that it holds a pipe side member 12 of a pipe joint 2 from left and right sides. The hook part 18 has a connection part 20 that is extended downward along a wall surface 21 of a structure 17 in one piece. The support part 19 is provided in one piece at the lower edge of the connection part 20 and has an engagement nib 22 that is provided at the lower edge of the connecting part 20 and is engaged to an engagement part 10 of the gas meter body 5 and a support piece 23 in a shape along an area near the engagement part 10.
