Abstract (en)
[origin: WO02077582A1] The invention relates to a device for determining and/or monitoring a predetermined filling level in a container, which can adapt as optimally as possible to any given application. Said device comprises the following: a mechanical oscillating body arranged at the height of the predetermined filling level, which has a membrane (3) and two oscillating rods (7) spaced from one another and formed thereon; an electromechanical transformer, which makes the oscillating body oscillate during operation in such a way that the oscillating rods (7) carry out oscillations perpendicular to the longitudinal axis; a receiver and evaluation unit (13), which serves to determine and/or monitor on the basis of said oscillations whether or not the predetermined filling level has been reached. The oscillating rods (7) have a shape, whereby the mass moment of inertia of an amount of liquid moved by the oscillating rods when dipped into the liquid is 0.2 times as big or bigger than the moment of inertia of the oscillating rod (7).
