An ultrasound flow meter for ultrasonic measurement of a fluid flow, the meter comprising a housing with a measuring tube inside, an ultrasound transducer 106, and a circuit board 102. The circuit board 102 is shaped such that at least two points on an edge of the circuit board 102, e.g., an edge of a through-going hole 108, serve to limit relative movement between the first ultrasound transducer and the circuit board 102 in a direction along a line spanned by the two points, such that the circuit board 102 serve to confine the ultrasound transducer 106 between the two points. In a specific embodiment, fixing means 110, 112, such as solder, e.g. Surface Mount Technology (SMD) soldering, a clip 110, 112 or bracing are arranged on the circuit board 102, which can fix the first ultrasound transducer 106 to the circuit board 102 and possibly simultaneously serve as electrical connections. In addition, the invention provides a method of manufacture of said ultrasound flow meter.
