A flow controller controls flow through a deformable conduit by compressingtheconduit. The conduit may be compressed along a section of its length. Thecontroller may include a cam driven by an actuator, the cam driving a clamp tocompress the conduit. The actuator may be a dial. The cam may be shapedsuch that the flow rate varies linearly with rotation of the dial. Thecontroller mayinclude a clicker to allow the controller to be set in a number of differentpositions,allowing ease of adjustment and preventing drift or accidental adjustment oftheflow rate.
