Abstract
An ultrasonic meter for recording a flow quantity dependent on a flow of a fluid, has a control device, a measuring tube having a plurality of side walls, mutually adjacent side walls being at an angle to one another, and through which the fluid can flow in a longitudinal direction of the measuring tube, and first and second ultrasound transducers which are arranged at a distance from one another in the longitudinal direction on the measuring tube. The first and second ultrasound transducers respectively contain one transducer element or a predetermined arrangement of a plurality of transducer elements. The ultrasound transducer can be driven by the control device in order to excite an acoustic wave conducted in a side wall of the measuring tube, and conducted through the fluid to the other ultrasound transducer and recorded there by the control device to determine a signal time of flight.
