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. 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.
