1. A method of controlling fluid flow through tubes, comprising the steps of:

  • clamping a continuous longitudinal pliable tube to a side of a measuring unit;

    sensing fluid flowing through the continuous longitudinal tube by sensing an exterior side wall portion of the tube; and

    regulating the fluid flowing through the tube by exerting pressure on another exterior side wall portion of the tube to form an opening and closing valve, wherein the steps of clamping, sensing and regulating the fluid occur without removing portions of fluid from the fluid flow pathway passing through the tube.
