Claim:
1. A method of configuring a vortex flow control device comprising a vortex chamber, an inlet and an outlet arranged at one end of the vortex chamber, wherein the method comprises the steps of: setting a target maximum flow rate through the outlet for a predetermined pressure at the inlet; setting a target vortex initiation flow rate through the outlet at which vortex flow within the vortex chamber initiates; determining the actual maximum flow rate through the outlet for the predetermined pressure at the inlet; determining the actual vortex initiation flow rate through the outlet; determining an error parameter based on at least one of the actual maximum flow rate and the actual vortex initiation flow rate and at least one of the target maximum flow rate and the target vortex initiation flow rate; comparing the error parameter against a target condition; and if the error parameter fails to satisfy the target condition, modifying at least one characteristic of the vortex flow control device so as to vary at least one of the actual maximum flow rate and the actual vortex initiation flow rate; wherein the error parameter is determined as a characteristic of a difference between the actual maximum flow rate and the target maximum flow rate, and a difference between the actual vortex initiation flow rate and the target vortex initiation flow rate.
