Abstract
An ultrasonic flowmeter includes at least a first, a second, and a third ultrasonic transducer, and a control and evaluation unit for controlling the ultrasonic transducers and for evaluating measured signals. The flowmeter is configured such that, during operation, the first and second ultrasonic transducers are arranged on a measuring tube offset relative to one another such that a measuring path is present therebetween. The measuring path is defined by the course of the ultrasonic measuring signal during operation. The third ultrasonic transducer is arranged on the measuring tube during operation such that an additional reference path is defined, which includes the course of the Lamb wave emitted by at least one ultrasonic transmitter into the measuring tube wall. The control and evaluation unit determines the velocity of a medium flowing through the measuring tube taking into account the propagation velocity of the Lamb wave in the measuring tube wall.
