摘要

In a device for detecting filling level of liquid in a container, a protective tube (6) extends over a membrane (5) which can be placed in vibration by an electromechanical transducer (4). In this way, bubbles which rise in the liquid cannot reach the membrane and induce a false measurement of low filling level.
