Abstract
Illustrated and described is an ultrasonic flowmeter for flowing media, that operates according to the transit time method, with a measuring tube and at least one transmitting and/or receiving head, in connection with which the transmitting and/or receiving head has a housing and an ultrasonic transducer with which ultrasonic signals can be emitted into the flowing medium and ultrasonic signals can be received from the flowing medium. The ultrasonic flowmeter for flowing media is characterized in that a damping device with at least one damping element is arranged around the sides of the housing of the transmitting and/or receiving head and at least partly adjacent to it, and the damping device is provided in a recess of the measuring tube.
