TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Clamp-on ultrasound cryogenic flowmeters using single crystal piezoelectric transducers are proposed to enable reliable, accurate cryogenic instrumentation needs in support of NASA Lunar Lander, Ground Operations, Altair, Ares, and Lunar Surface Systems programs. In-space, on the lunar surface, and on the Earth Exploration Systems architecture presents cryogenic storage, distribution, and fluid handling challenges that require new technologies to be developed. Clamp-on ultrasonic flowmeters are proposed because of their advantages such as high turn-down ratio, non-intrusive, no pressure drop, bi-directional measurement, no moving parts and fast response. Single crystal piezoelectrics are attractive because they exhibit 3 to 5 times the strain as conventional piezoelectric ceramics, and retain excellent piezoelectric performance at cryogenic temperatures (< 20 K). Cryogenic piezoelectric transducers with broad bandwidth and high sensitivity will be designed, fabricated and characterized, and cryogenic gas flow rate measurements will be performed using the developed cryogenic transducers. It is expected to have 10-20 dB sensitivity gain (combining transmitting and receiving) for clamp-on ultrasonic flowmeters by using novel single crystal piezoelectric transducers.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Cryogenic fluid instrumentation for cryogenic fluid transfer and handling systems to support NASA Lunar Lander, Ground Operations, Ares, and Lunar Surface Systems programs. Ultrasound NDE for large telescope components such as SiC mirrors, X-Ray telescopes, etc.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Ultrasonic flowmeters for industry process control such as natural gas custody transfer applications, emissions monitoring (flare gas and stack gas flowmetering), steam flow, oil flow, water flow, liquid level, temperature, density, gas molecular weight, etc. Apart from the fluid instrumentation, broadband, highly sensitive single crystal piezoelectric transducers are also good candidates for medical ultrasound, navy sonar and ultrasound NDE applications.
