Abstract

Die Erfindung betrifft eine Vorrichtung zum Messen der Strömungsgeschwindigkeit und/oder -rate eines fluiden Mediums, mit zumindest einem mechanischen Dehnkörper (12, 13), dessen Dehnung dem Druckabfall des Mediums über eine Strömungseinschnürung (9) unterworfen ist, und zumindest einem auf dem Dehnkörper (12, 13) angeordneten Dehnungsmeßstreifenelement (40-42), wobei der Dehnkörper (12, 13) rohrförmig aufgebaut und vom Medium axial durchströmt ist. Die Erfindung betrifft ferner einen Dehnkörper hierfür, mit zumindest einem darauf angeordneten Dehnungsmeßstreifen, wobei der Dehnkörper (12, 13) rohrförmig aufgebaut und vom Medium axial durchströmt ist und zumindest einen längsverlaufenden Schlitz (27) aufweist, der von einem dehnbaren Balg (28) überspannt ist.
