The Feedwater Supply Assembly in the Advanced Space Suit is a soft-walled, flexible reservoir containing cooling water. The water is circulated through the thermal control loop and slowly consumed by evaporation at the Suit Water Membrane Evaporator, rejecting waste heat to control occupant temperature. To ensure uninterrupted thermal control and occupant survival, it is critical to monitor the remaining water volume. The sensor developed under this program will accurately monitor the remaining volume in this reservoir. This sensor will function equally well in any other flexible fluid reservoir on a space platform. This may include fuel, coolant, and cryogen storage bladders on various spacecraft, satellites, and stations.
This sensor technology will meet similar bladder volume monitoring needs in other microgravity applications such as commercial spacecraft and orbital stations, along with water and fuel storage bladders used in military and recreational applications.
