Compact, High-Accuracy Oxygen Flow Meter

Life support systems for future space suits will require advanced instrumentation to enable use of the suit for multiple missions. We propose to develop an oxygen flow meter for the space suit ventilation loop that will provide highly accurate flow measurements while meeting challenging requirements for low pressure drop, compact size, and durability. In Phase I, we will prove the feasibility of our approach through analyses and trade-off studies, proof-of-concept demonstrations, and prototype design. In Phase II, we will design and assemble prototype flow meters and measure their performance under conditions that simulate operation in a portable life support system. More »
