摘要： The invention relates to an ultrasound flow sensor, comprising at least one ultrasound converter (A,B) for the transmission and receiving of ultrasound signals (A0,B0) and a receiver unit (4) arranged on the ultrasound converter (A,B) which detects a zero transition (N) of the ultrasound signal (A0,B0) as reception time, after the ultrasound signal (A0,B0) has exceeded a given threshold value (SW). The measurement accuracy of the sensor can be significantly improved, if the receiver unit (4) detects the time of a parameter characterizing the ultrasound signal (A0,B0) and records the relative time shift (deltat) of the characteristic parameter (Ampmax,Ts) as the zero transition (N0 or N1) detected as reception time (to).

摘要： A method for operating at least one ultrasonic transducer (116; 144, 146) is proposed. An excitation frequency is used to excite the ultrasonic transducer (116; 144, 146) to emit ultrasonic waves. At least one received signal (156) is detected by at least one control sensor (152). Emission is regulated to at least one desired frequency using the received signal (156).

摘要： The invention relates to an ultrasound flow sensor provided with at least one ultrasound converter (A,B) for transmitting and receiving ultrasound signals (A0,B0) and a receiver (4) which is connected to the ultrasound converter (A,B) and which determines a zero crossing (N) of the ultrasound signal (A0,B0) as a reception moment (to) after the ultrasound signal (A0,B0) exceeds a given threshold (SW). Measuring accuracy can be improved substantially if the receiver (E) determines information on the amplitude (Amp) of the ultrasound signal (A0,B0) and varies the threshold (SW) according to the information thus determined.

摘要： The invention relates to an ultrasonic flow sensor for measuring the volumetric flow of a flowing medium through a flow channel (24). Said sensor comprises a transducer array (2), which is located in the flow cross-section of the flow channel (24) and which generates ultrasonic waves (27) that are propagated in the flow cross-section of the flow channel (24) transversally to the flow direction (14) of the flowing medium. According to the invention, the ultrasonic transducer array (2) has a staggered arrangement of transducer elements (4), which act alternately as transmitting (10) and receiving antennae, in such a way that all emitted individual sonic waves (27) interfere to form common wave fronts (28).
