Non-Invasive Liquid Characterization Tools (433)
Problem: Need effective, portable methods and tools for non-invasive evaluation of liquids in closed containers.
Project Activity Scope (from Technical Overview Chart): Interaction Mechanisms through Integrated Systems.
PNNL Solution:
- Identified key measurement requirements and target liquids
- Performed laboratory evaluation of liquid properties
- Leveraged ultrasonic (UT) measurement equipment methods (augmented as necessary)
- Leveraged PNNL staff knowledge of fluid properties and dynamics
- Established liquid signature library/database
- Determined key properties to enable liquid identification and characterization
- Tailored UT measurement system to detect and discriminate key signatures
- Developed algorithms for rapid liquid evaluation
- Developed and demonstrated portable prototype instrumentation
- Designed and developed tools for liquids in large containers
- Designed and developed tools for liquids in small containers
Capabilities Employed to Meet Client Needs: Laboratory measurement of acoustic properties of liquids to develop signature library (targets of interest and common commercial/industrial liquids that might complicate the detection of the target liquids); analysis of library data to identify distinguishing signal features (signatures); develop and evaluate laboratory measurement systems to exploit key signature differences; design prototype equipment for practical method evaluation; develop data analysis algorithms and software for instrument control and data analysis; demonstrate instrument performance; document design and performance; train staff in system operation; commercialize instrument to ensure source of instruments to meet client requirements.
