Abstract
An ultrasonic flowmeter includes first and second ultrasonic transducers and a control and evaluation unit. The first and second ultrasonic transducers include respective transducer housings that are at least partially capable of mechanical oscillation and are at least partially excited to mechanical oscillations for signal emission or signal coupling. The control and evaluation unit controls the first and second ultrasonic transducers and evaluates a measurement signal characterizing a flow rate of a medium. The first ultrasonic transducer has a mechanical oscillation influencing element that influences oscillation behavior of the first ultrasonic transducer such that natural frequencies of the first ultrasonic transducer are frequency-shifted relative to natural frequencies of the second ultrasonic transducer. The measurement signal characterizing the flow rate, which results from the transmitted ultrasonic signal passing through the first and second ultrasonic transducers, is more broadband than after passing through only one of the first and second ultrasonic transducers.
