ABSTRACT:
A device for measuring the flow rate of a fluid with ultrasonic has a measuring tube (12) with ultrasound transducers (26), arranged in the area of its ends, as well as connecting pieces (16) for the inflow and discharge of the fluid which are arranged coaxially with respect to one another. The measuring tube (12) is arranged coaxially with respect to the connecting pieces (16) and the ultrasonic transducers (26) are positioned between the measuring tube and the connecting pieces. With this arrangement, the effective length (1) of the ultrasonic measuring section may be increased when the laid length (L) is predetermined.
