An ultrasound flow meter for ultrasonic measurement of a fluid flow, the meter comprising a housing with a measuring tube inside, and a mechanically separate unit 500 arranged in relation to the housing. The mechanically separate unit 500 comprises at least one ultrasound transducer 506 and a circuit board 502 with an electronic circuit 504 arranged for operating the at least one ultrasound transducer 506, wherein at least one fixing member, such as solder or clips, is attached to the circuit board 502. The fixing member serves to limit relative movement between the circuit board 502 and the ultrasound transducer 506. The fixing member may further serve to electrically connect the transducer 506 to the circuit board 502. In addition, the invention provides a method of manufacture of said ultrasound flow meter, preferably including testing the mechanically separate unit before attaching the mechanically separate unit to the housing.
