ABSTRACT:
A flexible diaphragm can be moved to line opposite surfaces of a tank vehicle so that incompatible fluids alternately can be transported in the vehicle without the need for cleaning it. Both sides of the diaphragm are vented to the atmosphere automatically whenever the vehicle container is filled with fluid. The diaphragm is prevented from entering a manway on the vehicle, and an outage gauge is confined entirely within the manway to prevent damage to the diaphragm.
