Measuring device for determining the flow in a tube

摘要

On this tube, two ultrasonic transducers are mounted obliquely opposite to one another. Each ultrasonic transducer contains an ultrasonic transducer element which is mounted on a wedge-shaped sound transmission part. To impart high measuring accuracy to such a measuring device even when a tube with a relatively small diameter is used, the sound transmission part (27) is pulled in at its side faces (36 and 37) with an angle of inclination which remains the same over the length of the base area (27b) in such a manner that its cross-section is at least partially trapezoidal. <IMAGE>
