Patent ID: 7810399

Claim:
An ultrasonic flowmeter with a measuring tube through which flows a medium and which, viewed in its cross section, has a bipartite split circumference forming two halves, and with two ultrasonic converter pairs, each with an associated ultrasound reflector, the ultrasonic converters of each ultrasonic-converter pair being mounted on a common circumferential half in a mutually offset position as viewed in the longitudinal direction of the measuring tube, while the ultrasound reflector for each ultrasonic converter pair is positioned on the other, opposite circumferential half in the longitudinal direction of the measuring tube between the two ultrasonic converters, in such fashion that an ultrasound signal emitted by one ultrasonic converter of an ultrasonic converter pair travels along a V-shaped signal path via the ultrasound reflector of the associated ultrasonic converter pair to the other ultrasonic converter of that ultrasonic converter pair, wherein the first ultrasound converter pair and the second ultrasound reflector are positioned on one circumferential half of the measuring tube while the second ultrasound converter pair and the first ultrasound reflector are positioned on the other circumferential half of the measuring tube, wherein the two V-shaped signal paths extend along different planes, the different planes do not intersect within the measuring tube and the measuring tube is oriented in a way whereby the ultrasound converters of all ultrasound converter pairs are positioned at a level higher than that of the associated ultrasound reflector.
