ABSTRACT:
A safety system for transfer of pressurized fluid between a cargo tank vehicle and a storage container. A pump or compressor on the cargo vehicle is in fluid communication with the cargo tank, the pump being powered by the vehicle. A pump valve on the vehicle between the tank and the vehicle pump will interrupt fluid passing into the pump. A delivery hose having a first end in fluid communication with the pump and a second end in fluid communication with the storage container transfers the pressurized fluid between the pump and storage container. A first pressure sensor senses pressurized fluid in the delivery hose near the hose second end. A first switch activated by the first pressure sensor closes the pump valve and interrupts the fluid flow. A second pressure sensor senses pressure near the hose first end. A second switch activated by pressure from the second pressure sensor closes the pump valve and interrupts fluid flow.
