Reliable and accurate cryogenic propellant instrumentation is needed in-space, on the lunar surface, and on the earth. The proposed development will ensure reliable flow measurements for rocket engine feed lines in NASA spacecrafts. The proposed electromagnetic flowmeter can also be used to significantly enhance the flow monitoring and control of space exploration systems including propellant management and acquisition, nuclear power conversion and propulsion, thermal management, bio-fluids and life support systems. In addition, the flowmeter will be applicable to NASA's ground tests, commercial space systems, and defense aviation systems.
Accurate flow measurements are required by many civil engineering practices in chemical, petroleum, biomedical, automotive and nuclear industries. In these industries, accurate identification and characterization of two-phase turbulent flows within pipes are essential to improve process quality. Although a great deal of flowmeters have been developed and are commercially available, the non-intrusive capacitance-based electromagnetic flowmeter is very competitive and will be among the best choices for measuring electrically non-conducting fluids.
