Abstract: An ultrasound flow meter unit arranged to measure a fluid flow rate with one or more ultrasound transducers (606), and a circuit board (602) with an electronic circuit arranged to operate the ultrasound transducer(s) (106, 306). The ultrasound transducer (606), e.g. in the form of a piezo-electric element, is mechanically fixed to the circuit board (602) by a first electrically conducting fixing means which additionally serve(s) to provide an electrical connection between an electrical terminal of the transducer (606) and the electronic circuit. Hereby a functional flow measurement unit (600) is provided which can be tested prior to assembly with a flow meter housing etc. Preferably, a set of ultrasound transducers (106, 306) are soldered directly onto electrically conducting paths (631) on a surface of the circuit board (602) being in electrical connection with the electronic circuit, e.g. in a single SMT mounting process together with mounting of all other electronic components on the circuit board (602). Through-going openings (630, 640) of the circuit board (602) in the vicinity of these conducting paths (631) serve to provide thermal elasticity. A metal clip soldered to the circuit board (602) may serve to electrically connect a second electrical terminal of the transducer (606) to the electronic circuit.

Abstract: An ultrasound flow meter unit, e.g. a unit forming part of a flow meter for ultrasonic measurement of a fluid flow. The unit comprises two ultra-sound transducers 206, a circuit board 202 with an electronic circuit 204 arranged for operating the ultrasound transducers 206, and a common protection membrane 132, such as a sheet of metal, for protecting the transducers 206. The common protection membrane 132 forms part of a water-tight casing, such as an IP68 class casing. The two ultrasound transducers 206 and the circuit board 202 with the electronic circuit 204 are positioned within the water-tight casing and thus protected against damaging humidity. A glass sealed feed-through 128 can be used to provide external electrical contact to the electronic circuit 204, i.e. for outputting an electric flow rate signal. Such flow meter unit is highly versatile within many applications since it provides a compact and robust unit. The unit can be used with or integrated in many types of devices, e.g. flow meters, such as used in consumption meters for charging purposes or in many other industrial or home applications.
