| description | To provide a structure for preventing wrong assembly of a component for measuring a flow rate of a gas meter, which can prevent wrong assembly of a measuring unit and a straightening plate simply and reliably.SOLUTION: In a portion of an internal gas flow passage formed at the bottom of a meter case 2 closed by a bottom cover 3, an inlet straightening plate 16, an ultrasonic measuring unit 15, and an outlet straightening plate 17 are mounted. Inside the bottom of the meter case 2, guide grooves 30, 25, and 26 for guiding the mounting of the measuring unit 15, the inlet straightening plate 16, and the outlet straightening plate 17 are formed, respectively. In the measuring unit 15, the inlet straightening plate 16, and the outlet straightening plate 17, protrusions 16f, 17f guided along the guide grooves 30, 25, 26 are formed, respectively. The combination of these guide grooves and projections prevents these components from being wrongly assembled in a state of being reversed.SELECTED DRAWING: Figure 3
【課題】計測ユニット、整流板の誤組付けを簡単かつ確実に防止可能なガスメータの流量計測用部品の誤組付け防止構造を提供する。【解決手段】底部カバー３で封鎖されるメータケース２の底部に形成される内部ガス流路の部分には、入口用整流板１６、超音波式の計測ユニット１５、出口用整流板１７が装着される。メータケース２の底部の内部には、計測ユニット１５、入口用整流板１６および出口用整流板１７の装着をガイドするガイド溝３０、２５、２６がそれぞれ形成されている。計測ユニット１５、入口用整流板１６、出口用整流板１７には、ガイド溝３０、２５、２６に沿ってガイドされる突起１６ｆ、１７ｆがそれぞれ形成されている。これらガイド溝と突起の組み合わせにより、これらの部品が前後逆の状態で誤組付けされることが防止される。【選択図】図３ |
