Abstract
An ultrasonic transducer for an ultrasonic flowmeter includes at least one electro-acoustic element, at least one housing, at least one acoustic window and at least one control unit. The electro-acoustic element is arranged within the housing on the acoustic window such that, during operation, an ultrasonic signal generated by the electro-acoustic element leaves the housing through the acoustic window. The electro-acoustic element has at least two electro-acoustic discs. The at least two electro-acoustic discs are arranged one above the other. At least one electro-acoustic disc can be excited separately, at least temporarily, by the control unit.
