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.
