A device for detecting the filling condition in a container has an electro-mechanical transducer 4 secured on a diaphragm 5, by which transducer the diaphragm 5 is set in vibration. An electrical unit energizes the transducer to produce oscillations of the diaphragm 5. The diaphragm 5 has a holder 1 on which the diaphragm 5 is fastened by means of a cylindrical intermediate member 6. The wall thickness of the cylindrical member 6 is a multiple of the thickness of the diaphragm 5.
In a system for detecting a filling level for a liquid in a container, a device mountable on the container for detecting a level during filling, storage and evacuation of liquid of the container, the device having an electro-mechanical transducer mounted on a diaphragm, by which transducer the diaphragm is placed in oscillation, there being electrical means for initiating oscillations of the diaphragm, the device including a holder of the diaphragm and an intermediate cylindrical member, the diaphragm being secured to the holder by means of the intermedi...
