Abstract
A pump system includes an interface detection meter arranged at a pipeline assembly, a drive assembly for controlling speed of a pump arranged at the pipeline assembly, a discharge pressure control assembly and/or flow control assembly for controlling discharge pressure of the pump system, and a control assembly operably coupled to the drive assembly and/or the discharge pressure control assembly and/or the flow control assembly. A logic control of the control assembly receives fluid data of fluid in the pipeline assembly provided by the interface detection meter, and forwards the fluid data for calculating speed set points for the drive assembly and/or discharge pressure control parameter and/or set points for the discharge pressure control assembly, and/or flow rate control set points for the flow control assembly. A method for controlling variable speed driven pumps or pump systems during batch change and an embodiment of a plug-and-play device are disclosed.
