A flow control system for a flow of a cryogenic fluid over a component is provided. The system includes a first tubing containing a first fluid therein and positioned upstream of the component with respect to the flow of the cryogenic fluid. The system includes a second tubing containing a second fluid therein and positioned downstream of the component with respect to the flow of the cryogenic fluid. The system also includes a parameter sensing device fluidly connected to the first tubing and the second tubing for comparing a first parameter associated with the first tubing and a second parameter associated with the second tubing. The system further includes a flow control device coupled to the parameter sensing device to regulate the flow of the cryogenic fluid over the component based, at least in part, on the comparison.
