A method for detection of a fluid leak related to at least one piston machine (1), where the method includes: - attaching a pressure sensor (18, 24) to at least a pressure side of the at least one piston machine (1); - measuring the pressure on the pressure side of the at least one piston machine (1); - attaching a transmitter (28) to the at least one piston ma-chine (1), said transmitter (28) rendering a signal for cal-culating the rotational speed of the at least one piston ma-chine (1); - calculating the speed of the at least one piston machine (1); - calculating the sum of nominal flow rates from all piston machines(1); - calculating a flow rate compensation factor; - calculating a normalized pressure (42) to be equal to the discharge pressure multiplied by the said compensation factor for the flow rate; and - monitoring the normalized pressure (42) to detect a leak-age.
