Abstract
A container replacement system for replacing a fluid container with a replacement fluid container, wherein the fluid container contains a cryogenic fluid and is coupled to a pressure line, includes a control valve that vents the cryogenic fluid within the pressure line, a pressure sensor that senses a line pressure of the cryogenic fluid and generates sensor output and a controller that receives sensor output and determines whether to replace the fluid container. If the line pressure is below a threshold line pressure, the controller determines replacing the fluid container is permissible. Contrarily, if the line pressure is above the threshold line pressure, the controller determines replacing the fluid container is not permissible. The container replacement system further includes a GUI that instructs whether replacing the fluid container is permissible.
