1. An ultrasonic transducer for the measurement of fluid volumes, comprising:
a housing in which a contact element and a piezoceramic are arranged, where said piezoceramic includes two electrodes of different polarity which are applied onto different sides of said piezoceramic, where contact surfaces for electrical contact of said two electrodes are arranged on the same side of said piezoceramic; and
said contact element including at least two contact sections of different polarity which are in electrically conductive contact with said contact surfaces of said two electrodes of corresponding polarity, where said contact element forms a part of said housing, wherein
said contact element is pot-shaped, where said contact sections are arranged at a base of said contact element and are electrically contactable by way of edge sections of said contact element protruding from said base.
