ABSTRACT:
To provide a precise determination and/or control of a filling level in containers, two vibrator elements (10, 12; 48, 52) are arranged one on top of the other and/or coaxially to each other, and at least partially encompass themselves in spaced relation to each other. They are configured like rotary vibrators having the same resonance frequency and are excited to vibrations of opposite sense of rotation for determining the filling level, whereby only one vibrator element comes into direct contact with the filling material in the container. This results in no vibration energy being transmitted to the container walls and thus the quality of the measurements is increased.
