Patent ID: 7917313

Claim:
A computer implemented method for monitoring a fluid transfer process, comprising: providing an allowable pressure profile on a storage device, wherein the providing an allowable pressure profile comprises: acquiring a family of pressure courses as a function of time of a plurality of fluid transfer processes, and providing a frequency distribution of the acquired family as a function of time and determining a minimum limit course and maximum limit course corresponding to a predefined value of the at least one statistical parameter of the family, wherein at least one of the interpolation points is a point of one of the limit courses and all interpolation points are external to the area confined between the minimum limit and the maximum limit, the at least one statistical parameter comprising the variance of the family of pressure courses; detecting, by way of one or more pressure sensors, a pressure occurring in the course of the fluid transfer process; comparing the detected pressure with the allowable pressure profile; signaling an error, if the detected pressure is not within the allowable pressure profile; wherein the allowable pressure profile is defined by interpolation points, the interpolation points being based on a probability function representing a family of pressure courses of a plurality of fluid transfer processes.
