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: The invention provides a pressure sensor device arranged for measuring a pressure in a fluid pipe system, e.g. a utility network. A measurement system with a pressure sensor serves to measure pressure in the fluid pipe system, and a data processing unit determines at least one statistical parameter in response to a plurality of pressure measurements. Data packets with the statistical parameter is then transmitted by means of a communication module, e.g. via a data network which serves for remote reading of utility meters. The statistical parameter is selected from the second, third and fourth statistical moments of the pressures measured with the plurality of measurements of pressure. The pressure sensor device in a battery driven form can be placed at remote locations in a fluid pipe system to monitor pressure transients, e.g. in a water distribution system. Especially, a time stamp may follow the statistical parameter(s) sent, such that it is possible to track pressure transient creating events on the fluid pipe system.
