ABSTRACT:
An ultrasonic flowmeter with a measuring tube through which flows a medium and which, viewed in cross section, has a split circumference forming two halves with two ultrasonic converter pairs, each with an associated ultrasound reflector. The converters of each pair are mounted on a common circumferential half in a mutually offset position as viewed in the longitudinal direction of the tube, while the reflector for each pair is positioned on the other, opposite circumferential half in the longitudinal direction of the measuring tube between the two converters, so that an ultrasound signal emitted by one converter of a pair travels along a V-shaped signal path via the reflector of the associated pair to the other converter of that pair. The first pair and the second reflector are positioned on one circumferential half of the tube while the second pair and the first reflector are positioned on the other, opposite circumferential half of the tube.
