Summary: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 posi-tioned at the top and bottom of the tank. The pres-sure 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 conver-ter within the fixed fluid control system. The con-verter 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.
