Abstract
A method of forming a flow restriction in a fluid communication system is disclosed. The method comprises the steps of providing a flow restricting section having a cross sectional area and a length, measuring the flow resistivity of the flow restricting section, and modifying the cross sectional area and/or the length of the flow restricting section until a desired flow resistivity of the flow restricting section is obtained. The method provides the possibility of forming a flow restriction in an easy and cost effective manner, and to subsequently adjust the flow resistivity of the flow restriction, thereby obtaining an accurate flow resistivity.
