1. A system for accurately delivering fuel to a target fluid vessel, comprising:
a fluid flow meter disposed in line of a fuel delivery conduit to measure an amount of a flow of fuel passing through the conduit;
a density measuring device comprising a body at least a portion of which is disposed in the conduit to operably determine the real-time density of the fuel that passes through the fluid flow meter; and
a control unit comprising a processor, the control unit receiving data indicative of the amount of fuel measured by the fluid flow meter in volume, and receiving data indicative of the real-time density of the fuel from the density measuring device, the control unit using the processor to:
convert the measured volume of fuel to a unit of mass of fuel that passes through the fluid flow meter; and
determine an amount of fuel to be dispensed in real-time to reach a target total mass of fuel, based at least upon an existing mass of fuel in a target aircraft and the target total mass of fuel.
