Abstract
A method of manufacturing an ultrasound flow rate measurement apparatus is provided, wherein at least one pocket for an ultrasonic transducer is manufactured from the outside in a line wall of a line section in which a fluid flows in operation and an ultrasonic transducer is arranged in the pocket, wherein the ultrasonic transducer has an oscillating body that couples to a part region of the line wall and that acts as a membrane of the ultrasonic transducer capable of vibration. In this respect, a manufacturing step of the pocket has a drilling procedure and a coupling piece is manufactured with the pocket and is arranged between the membrane and the oscillating body after the insertion of the ultrasonic transducer and its cross-section is smaller than the cross-section of the oscillating body.
