Abstract (en)
[origin: WO03098166A1] The invention relates to an ultrasonic transducer for an ultrasonic flow-rate meter, wherein several piezo elements (40.1 - 40.n) can be controlled in a time-delayed manner by means of a control logic (20), whereupon the direction of propagation of the radiated ultrasonic waves can be varied within a wide range.
