Abstract
A portable fueling control system is provided for delivering bulk fuel to a vehicle from a pressurized source. The portable system includes a fluid driven power source for operating auxiliary instrumentation of the system. An inlet receives the bulk fuel from the pressurized source. The inlet has a primary fluid path and a secondary fluid path. A first flow rate control is in fluidic communication with the primary fluid path for adjustably controlling the flow rate of bulk fuel from the pressurized source to a system outlet. A first monitor is operably linked to the secondary fluid path and the first flow rate control. The first monitor is responsive to the flow rate of the secondary fluid path for actuating the first flow rate control to vary the pressure difference across the first flow rate control. In this way, the adjustment of the first flow rate control causes a proportional change in the fluid flow rate of the secondary path for operating the fluid driven power source at a substantially constant flow rate as bulk fuel is provided to the outlet at a variable flow rate.
