Patent ID: 6968871

Claim:
A fluid transfer system useful for transferring hazardous fluids within a closed environment, the system comprising: fluid storage means for storing a fluid within a closed environment; first flow control means operable with the fluid storage means for delivering a fluid from a source location thereto while maintaining the fluid within the closed environment; sensing means for sensing an amount of fluid carried by the fluid storage means, wherein the sensing means comprises a pressure sensor operable for sensing pressure responsive to the fluid received by the fluid storage means; second flow control means operable with the fluid storage means for delivering the fluid therein to a target location while maintaining the fluid within the closed environment; a vapor line in fluid communication between the target location and the source location for transferring vapor from the target location to the source location within the closed environment and responsive to the target location receiving the fluid; and processing means operable with the first and second flow control means for controlling fluid flows therewith in response to an amount of fluid sensed by the sensing means.
