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