    摘要： An ultrasonic flow sensor for detecting a flow of a fluid medium in a flow tube includes at least one first ultrasonic transducer, at least one second ultrasonic transducer, and at least one waveguide configured to conduct ultrasonic waves between the at least one first ultrasonic transducer and the at least one second ultrasonic transducer by reflection on walls of the waveguide, and to enable the fluid medium to flow through. The ultrasonic waves are able to propagate between the first ultrasonic transducer and the second ultrasonic transducer on at least two ultrasonic paths.

    摘要： An ultrasonic flow sensor having at least one ultrasonic converter (A, B) for transmitting and receiving ultrasonic signals (A0, B0) and a receiver unit (4) that is connected to the ultrasonic converter (A, B) and determines a zero crossing (N) of the ultrasonic signal (A0, B0) as a reception time (t0) once the ultrasonic signal (A0, B0) has exceeded a predetermined threshold value (SW). The measurement precision can be significantly improved if the receiver unit (4) determines a piece of information about an amplitude (Amp) of the ultrasonic signal (A0, B0) and varies the threshold value (SW) based on the information determined.

    摘要： The invention relates to a method for determining the running time (t) of an ultrasound flow sensor (6) ultrasound signal (15) which is transmitted by an ultrasound transducer (A, B) to a measuring section (S), wherein the phase position (ΔF) of said ultrasound signal (15) is determined with respect to a reference clock (8) and a remaining part (r(t)) is determined as a measure of the running time (tmes) of the ultrasound signal (15). The measurement of the running time can be carried out in a particularly robust manner with a minimum use of hardware, when the phase position (ΔF) is determined with the aid of a quadrature-demodulation method consisting in inverting the received signal (15) in a segmented manner with the aid of a clock signal (8) and the phase of the off-set clock signal (9) and the remaining part (r(t)) is determined according to a characteristic quantity (ts) of the sound signal (15).
