1. A method for regulating pressure at a distal end of a fluid line, the method comprising:

  • providing a fluid flow control system, the fluid flow control system having at least one liquid volume in valved communication with. the distal end, a control volume in pressure communication with the liquid volume, means for measuring pressure in the control volume, and means for adjusting the pressure in the control volume;

    calibrating the means for measuring the pressure;

    establishing communication between the liquid volume and the distal end;

    measuring a pressure of the control volume; and

    adjusting the pressure in the control volume in accordance with the measured pressure.
