Abstract
A method for detecting a characteristic of a flow of a liquid in a pipe for intended use in determining a transition among or between two products forming the flow is disclosed. The method may comprise obtaining a first signal representative of the characteristic of the flow, determining when a substantial change in the characteristic is occurring; determining the transition point, and determining a transition time for the substantial completion of the transition based on parameter(s) generated from the first signal.
