The invention uses a derivative of , preferably the nozzle pressure, and inputs this to a fuzzy inference system. The fuzzy inference system uses said rules and knowledge to provide a suitable transfer time as an output. It is preferred that the sample pressure is filtered prior to calculation of the derivative.
