Abstract: A method for detecting leakage in a fluid system, comprising: receiving a pressure signal indicative of measured pressure values of a pressure in the fluid system measured at different points in time; determining a first filtered pressure signal indicative of variations of the measured pressure values over a first time scale; determining a second filtered pressure signal indicative of variations of the measured pressure values over a second time scale, shorter than the first time scale; outputting a leakage warning based on a comparison of the first filtered pressure signal and the second filtered pressure signal.
