Beschreibung
Zusammenfassung:	The present invention discloses a method of measuring the flow rate of a fluid flowing through a flow passage within a control valve assembly, the method comprising the steps of: providing a control valve assembly including a throttling element moveable within the flow passage and an intelligent positioner adapted to sense a position of the throttling element within the flow passage; providing a flow measurement module; communicatively coupling the flow measurement module to the intelligent positioner without disrupting the flow of the fluid flowing through the flow passage; and generating a flow rate signal representative of the flow rate of the fluid flowing through the flow passage based on sensed pressures upstream and downstream of the throttling element and based on the sensed position of the throttling element within the flow passage.
