An electronic arrangement for analyzing fluid flow, includes a measuring entity for obtaining indications of power or energy consumption associated with fluid flow relative to a predetermined element, at multiple time instants, during measurement periods, each measurement period occurring between similar subsequent maintenance operations affecting the energy consumption of the element, wherein the measurement indications for the period are utilized for modeling, with reference to the true operating time of the element and excluding non-operating time potentially between active periods, a modeling entity for maintaining a regression model constructed based on indications for measurement periods, the model including a response variable for providing an indication of power or energy consumption during a measurement period and an explanatory variable for representing time, and wherein the model regarding the previous measurement period between the second-last maintenance and the last maintenance is taken as a starting point for the model being currently updated. |
