Abstract: An aircraft refueling system (10) includes a master controller (12), a fleet controller (14) in communication with the master controller, a platform controller (18) in communication with the fleet controller, and a fuel control system (16) in communication with the platform controller. Embodiments of an aircraft refueling system may include a primary pressure controller (20), a secondary pressure controller (22), a programmable logic controller (24), and a data logger controller (26). The master controller may be configured to receive and analyze data from at least one of the fleet controller, the platform controller, and the fuel control system; and to modify operational parameters or upgrade the fuel control system based at least in part on the analysis of received data.

Abstract: A housing for a gas sensor module is described herein. The housing can include an outer portion and an inner portion disposed within the outer portion. The outer portion can include at least one wall forming a first cavity. The outer portion can also include an inlet tube coupling feature disposed at a first location in the at least one first wall, and an outlet tube coupling feature disposed in a second location in the at least one first wall. The inner portion can include at least one second wall forming a second cavity, and a distribution channel coupling feature disposed at a third location in the at least one second wall. The inner portion can also include a receiving channel coupling feature disposed in a fourth location and a tuning fork coupling feature disposed at a fifth location in the at least one second wall.
