Abstract
A measuring system, embodied as a clamp-on, ultrasonic, flow measuring device, comprises a tube, or a pipe, having a lumen surrounded by a tube, or pipe, wall, which tube or pipe is adapted to guide a volume portion of the fluid in its lumen; an ultrasonic transducer mounted on the tube, or pipe, on an outside of the tube, or pipe, wall facing away from the lumen, and acoustically coupled via the tube, or pipe, wall to fluid guided in the lumen, and adapted to convert a time varying electrical voltage into ultrasonic waves propagating through the tube, or pipe, wall and further through fluid guided in the lumen; an ultrasonic transducer mounted on the tube, or pipe, separated from the ultrasonic transducer on the outside of the tube, or pipe, wall, and acoustically coupled via the tube, or pipe, wall to fluid guided in the lumen, and adapted to receive ultrasonic waves propagating through fluid guided in the lumen, and further through the tube, or pipe, wall and to transduce such into an electrical voltage varying as a function of time; as well as an operating- and measuring electronics adapted to generate, a driver signal for the ultrasonic transducer. The driver signal has a time…
