Description
Claims (1)
- 一端が開口した筒状体を有する振動管と、渦発生体により生じた渦変動圧力を受圧可能とするように該振動管の端部に取り付けられた受圧板と、該振動管内部の空胴部内に挿入されて、前記受圧板の振動を検知して外部に電気信号として伝達する渦検出センサ部とを備え、該渦検出センサ部は、応力或いは歪を検出する検出素子を貼着しかつ振動管の上部開口側に圧入される上端圧入部を持つ弾性母材を有する渦流量計において、
小径にした円筒状の弾性母材先端部に、ネジ或いはリベットからなる溶接部材を嵌合するための嵌合穴を設け、
前記弾性母材はその端部に、外径が振動管の内径よりも僅かに大きい円板状をして、複数の放射状のスリット或いは切欠きが穿設されたバネ性を有するスリット板を固着し、
該スリット板の固着は、前記弾性母材先端部に載置した該スリット板を、前記嵌合穴に前記ネジを嵌合するか或いは前記リベットを圧入することにより固定した後、該ネジ或いはリベットからなる溶接部材を前記弾性母材に対してスポット溶接することにより行うことを特徴とする渦流量計。
