Abstract

The invention relates to a level meter (1) with an outer oscillating body (3) and an inner oscillating body (4), which bodies are coaxially positioned relative to a longitudinal axis (X), with a drive and reception device (7) for exciting an oscillation in the oscillating bodies or for detecting an oscillation in the oscillating bodies, with a diaphragm (61) for elastically coupling one of the oscillating bodies (3), and with a clamping device (8) for clamping the drive and/or reception device (7) against the oscillating bodies. The level meter is advantageously characterized by the diaphragm (61), which runs in a lateral direction relative to the longitudinal axis (X) of the outer oscillating body (3) and on the outside passes into a transitional element (5, 51), said transitional element (5) being positioned between the drive and/or reception device and the inner oscillating body for the purpose of transmitting the oscillations between the drive and/or reception device and the inner oscillating body, and said transitional element (5) running in part, with one wall (54), in a lateral direction adjacent to the diaphragm (61); the clamping device, which clamps the diaphragm (61) and…
