Abstract
An infusion system and method for controlling the fluid flow from a pump includes a pump system that has a controller that utilizes an algorithm to control the flow rate of fluid through tubing. A plurality of electrodes operatively contacts an electrically conductive portion of the tubing that is also acted upon by the pump system. The electrodes monitor electrical properties of the tubing and provide an electric signal indicative thereof to the controller, which varies the flow rate of the fluid through the tubing as a result of the electric signal.
