Title
(JA) 管の共振周波数を測定するシステムおよび方法
Abstract
(JA)

本発明は管の共振周波数を測定するシステムを提案する。本システムは:・複数の振動周波数においてそれぞれ管を振動させる振動ユニット(21)と;・管が各振動周波数で振動させられるときに管内の第一の位置から第二の位置への圧力パルの伝達の時間遅延を検出する検出ユニットであって、管が前記複数の振動周波数の特定の振動周波数範囲内の各振動周波数において振動させられるとき、前記検出ユニットは前記時間遅延の変動を検出する、検出ユニット(22)と;・管が前記特定の振動周波数範囲内の諸振動周波数で振動させられるときの前記時間遅延の最大変動を判別する判別ユニット(23)と;・前記管の共振周波数である、前記時間遅延の前記最大変動に対応する振動周波数を示す指示ユニット(24)とを有する。
