Method for detection of fluid leakage through a membrane in a fluid flow control system. The fluid flow control system has a first chamber and a second chamber. A membrane is disposed between the first chamber and the second chamber. The second chamber has a connection to a pressure tank, the pressure tank has a fluid with a pressure, and the connection defines a fluid path. The method includes in a first step blocking the fluid path. The pressure of the fluid in the pressure tank is then adjusted. The rate of change of pressure is measured in the pressure tank. A blocked pressure rate is calculated. Next, the fluid path is unblocked. The rate of pressure change is measured within the pressure tank. An unblocked pressure rate is calculated. Finally a leakage rate is calculated based on the blocked pressure rate and the unblocked pressure rate.
