       2 . Method according to  claim 1 , wherein the measuring device ( 8 ) is introduced into the molten metal ( 4 ) from a drop station ( 6 ).  
   
   
       3 . Method according to  claim 1 , wherein the method is carried out automatically.  
   
   
       4 . Method according to  claim 1 , wherein the measurement data are transmitted in the wavelength range of the ISM bands.  
   
   
       5 . Device ( 3 ) for determining at least one characteristic of a molten metal ( 4 ), having a measuring device ( 8 ), by means of which measurement data of this characteristic can be generated, and a processing device ( 7 ) arranged outside of the molten metal, by means of which these measurement data can be processed, whereby the measuring device ( 8 ) can be introduced into the molten metal ( 4 ) to perform a measurement, wherein the measuring device ( 8 ) has an integrated transmission antenna ( 14 ), which is arranged at least partly above a slag layer ( 27 ) that is located on top of the molten metal ( 4 ), when the measuring device ( 8 ) floats in the molten metal ( 4 ), and wherein the measurement data are directly transmitted from the measuring device ( 8 ) to the processing device ( 7 ), in wireless manner.  
   
   
       6 . Device according to  claim 5 , wherein the measuring device ( 8 ) has an integrated transmission antenna ( 14 ), which is arranged at least partly above a slag layer ( 27 ) that is located on top of the molten metal ( 4 ), when the measuring device ( 8 ) floats in the molten metal ( 4 ).  
   
   
       7 . Device according to  claim 6 , wherein the transmission antenna ( 14 ) is mantled by a coating ( 18 ).  
   
   
       8 . Device ( 3 ) according to  claim 7 , wherein the measuring device ( 8 ) can be introduced into the molten metal ( 4 ) from a drop station ( 6 ).  
   
   
       9 . Device ( 3 ) according to the above claim, wherein several measuring devices ( 8 ) can be magazined in the drop station ( 6 ).  
   
   
       10 . (canceled)  
   
   
       11 . Measuring device ( 8 ) for being introduced into molten metal ( 4 ) and generating measurement data of at least one characteristic of the molten metal ( 4 ), wherein a transmission antenna ( 14 ) integrated into the measuring device ( 8 ) is arranged at least partly above a slag layer ( 27 ) that is located on top of the molten metal ( 4 ), when the measuring device ( 8 ) floats in the molten metal ( 4 ), and wherein the measurement data can be directly transmitted from the measuring device ( 8 ) to a processing device ( 7 ) that is located outside the molten metal ( 4 ), for processing of these measurement data, in wireless manner.
