ABSTRACT:
Improvement to a gas/liquid ultrasonic flowmeter in which focusing profiling (501, 502, 503) is provided in the measurement tube thereof for at least one of the plurality of reflection points of the ultrasonic path (21) of the useful signal, in such a manner that the beam of this beam path (21) is concentrated onto the surface of the reception transducer (FIG. 3 ). If required, the focusing reflection is provided for the path of the ultrasonic radiation (22) of the substantial interference signal component.
