Abstract
An ultrasonic fluid-flow measuring device in which a measuring tube having a rectangular cross section and a measuring tube wall lying opposite a pair of ultrasonic transformers is provided. The device utilizes three flat surface elements angled with respect to each other to reflect an ultrasonic beam so as to guide its passage through the fluid. Such structure provides a device in which the flow of the fluid is not impaired at any place in the measuring tube, and in which the inner walls of the measuring tube are free of niches which might promote the deposition of particles located in the fluid.
