<p num="1"><br/><br/><br/><br/><br/> ABSTRACT<br/> A fixed fluid control system for loading<br/>fluids into sealed tanks includes pressure sensing<br/>conduits in a mobile vehicle and fixed fluid controls.<br/> In the vehicle are first and second pressure sensing<br/>conduits having portions within the sealed tank posi-<br/>tioned at the top and bottom of the tank. The pres-<br/>sure sensing conduits have exterior portions to which<br/>are detachably coupled additional pressure sense<br/>lines. The additional pressure sensing conduits are<br/>coupled to a differential pressure to current conver-<br/>ter within the fixed fluid control system. The con-<br/>verter produces a current signal proportional to the<br/>pressure difference between the two sense lines. When<br/>this current reaches a predetermined high level, the<br/>supply of fluid to the sealed tank is discontinued.<br/><br/> |
