In-Line Fluid-Slurry Density Measurement (93)

Two inch diameter pipe segment with built-in sensor for in-process deployment.

Problem: A compact, in-line densitometer was needed for in-process analysis that is unaffected by equipment noise

Project Activity Scope (from Technical Overview Chart): Measurement and Analysis Method Development through Integrated Systems

PNNL Solution:

  • Established ultrasonic method can determine density for required samples
  • Developed in-line densitometer probe for real-time analysis of fluids and slurries
  • Granted US Patent # 5,708,191
  • Successful demonstration at Oak Ridge
  • Developing system for Hanford waste transfer pipeline monitoring

Capabilities Employed to Meet Client Needs:

  • Ultrasonics - sensor configuration, integration
  • Data acquisition - developing the electronics and unique electronics boards required to automate the sensor
  • Fluid dynamics - of multiphase systems during mixing and transport to evaluate probe performance
