ABSTRACT:
A fixed fluid control system for loading fluids into sealed tanks includes pressure sensing conduits in a mobile vehicle and fixed fluid controls. In the vehicle are first and second pressure sensing conduits having portions within the sealed tank positioned at the top and bottom of the tank. The pressure sensing conduits have exterior portions to which are detachably coupled additional pressure sense lines. The additional pressure sensing conduits are coupled to a differential pressure to current converter within the fixed fluid control system. The converter produces a current signal proportional to the pressure difference between the two sense lines. When this current reaches a predetermined high level, the supply of fluid to the sealed tank is discontinued.
