摘要： A method for operating an ultrasonic flowmeter includes: capturing at least one first ringing signal of a first ultrasonic transducer of the ultrasonic flowmeter, and detecting a first ringing debugging signal based on the at least one captured first ringing signal; emitting a first measurement signal into a medium through the first ultrasonic transducer, resulting in a first ringing measurement signal in the first ultrasonic transducer; receiving a measurement signal as a first received signal by the first ultrasonic transducer, wherein the first received signal and the first ringing measurement signal are superimposed to form a first superimposed signal; determining a first correction signal by subtracting the first ringing debugging signal from the first superposition signal; and determining the flow velocity or flow rate of the medium based on the first correction signal.

摘要： An ultrasonic flowmeter is provided with at least one measuring tube having at least one recess. Disposed in the recess are at least a first ultrasonic transducer and a second ultrasonic transducer, wherein the first ultrasonic transducer is designed as an ultrasonic transmitter and/or as an ultrasonic receiver and the second ultrasonic transducer is designed as an ultrasonic transmitter and/or as an ultrasonic receiver. Further disposed in the recess is at least one reflection surface. The first and second ultrasonic transducers are arranged on the measuring tube such that the measuring path between the first and the second ultrasonic transducers comprises at least one reflection at the reflecting surface. The provision of the reflection surface in the recess provides an ultrasonic flowmeter with which the flow profile can be easily measured, especially in the edge region.

摘要： A device includes a flow straightener insertable into a measuring tube of an ultrasonic flowmeter, a reflector device including a reflector body and an ultrasonic reflector on the reflector body, and a carrier having first and second carrier ends. The first carrier end is connected to the flow straightener. The second carrier end supports the reflector body. When the flow straightener is in the tube, the device is in an interior of the tube and the ultrasonic reflector deflects an ultrasonic measurement path emanating from the flowmeter so that the path extends through the interior along a longitudinal axis of the tube. The flow straightener has a first rotational symmetry about a first symmetry axis, and the carrier has a second rotational symmetry about a second symmetry axis. The first and second symmetry axes are coaxial. The ultrasonic reflector is spaced from the flow straightener along the second symmetry axis.

摘要： A method for operating an ultrasonic flowmeter includes the steps of: emitting a measuring signal having a first part that propagates as an interference signal along and/or within a wall of a measuring tube, and a second part that propagates as a useful signal through a medium flowing through the measuring tube; receiving the interference signal and the useful signal; determining an interference amplitude of the interference signal and determining a useful amplitude of the useful signal; determining an amplitude ratio of the useful amplitude and the interference amplitude; and providing a message if the amplitude ratio falls below a specified lower limit value or exceeds a specified upper limit value. A related ultrasonic flowmeter is also disclosed.

摘要： 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.
