摘要： An ultrasonic particle measuring system having an ultrasonic transducer with at least one ultrasonic transducer element and at least one coupling element, wherein, during operation, acoustic signals are transmittable and receivable by the ultrasonic transducer element via the coupling element, wherein the coupling element is embodied as an acoustic lens, and the ultrasonic, particle measuring system has an evaluation unit suitable for amplitude analysis of reflection signals of acoustic signals reflected from particles to the ultrasonic transducer, and wherein, with the evaluation unit, amplitudes of reflection signals in a predetermined time interval are countable, which are greater than a predetermined threshold value.
