摘要： A fill-level measuring device with a membrane, which is placed in such a manner on one of the two end region of a tubular housing that it seals the housing on such end region. An oscillatable unit is placed on the side of the membrane facing away from the housing, with a driver/receiver unit, which is composed of a plurality of piezoelectric elements arranged in a stack. The driver/receiver unit is placed via a pressure screw unit in such a manner in the housing that it oscillates in the direction of the longitudinal axis of the housing between the membrane and the pressure screw unit. The driver/receiver unit excites the oscillatable unit via the membrane to execute oscillations, with a control/evaluation unit, which evaluates amplitude, frequency and/or phase of the oscillations of the oscillatable unit and with a temperature sensor for determining temperature of the medium. The temperature sensor is integrated in a fill-level measuring device element, which is in thermal contact with the medium via the membrane or the housing, wherein the element is so selected that the oscillatable unit oscillates unimpaired by the temperature sensor.
