TECHNICAL ABSTRACT (LIMIT 200 WORDS)
Advanced Technologies Group, Inc. proposes the development of a Cryogenic Flow Sensor (CFS) for determining mass flow of cryogens in spacecraft propellant management. Current point sensor technology is incapable of determining high pressure, high flow rate cryogenic fluid quality and mass flow rate, and has proven to be inaccurate in attempting to rapidly measure cryogen depletion. If there is an abrupt change in fluid quality, turbo-machinery can over-speed causing catastrophic failure. The CFS will provide a means to avoid these failures as well as providing fluid quality data for a wide range of flow systems. Experimental hardware was able to detect the onset of two-phase flow and the presence of debris in the flow of water. The innovation clearly shows that it can discern between entrained gas bubbles and unwanted debris. The sensor has the potential to determine size and quantity of the contaminant. In addition, a non-intrusive method for determining the Mass-Flow?Rate of the fluid propellant has been designed, and is the focus of this phase I effort. A cryogenic sensor with these capabilities is very desirable to the cryogenic fluids management community, as well as other fluid management systems, and has many commercial applications.

POTENTIAL NASA COMMERCIAL APPLICATIONS (LIMIT 100 WORDS)
The more technically challenging application of producing a cryogenic fluid quality sensor, has been requested by both NASA SSC and NASA MSFC. SSC has requested the sensor for monitoring test stand propellant quality. MSFC is interested in the ability to monitor In-Space cryogenic fluids handling and In-space cryogen propellant lines.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (LIMIT 100 WORDS)
The commercial product that will be developed out of this phase III program, is a non-intrusive debris and two-phase mass flow sensor. At the present time there is no commercially available sensor capable of providing a non-intrusive means of measuring fluid quality. The Cryogenic Flow Sensor developed in this program has tremendous competitive advantage. Not only will it be capable of highly reliable measurement of fluid quality, but it will also be cost effective and easily installed in existing facilities.
