Coriolis versus Thermal Mass Flow for Gases and Liquids

Instrumentation Flow
1

What are the differences, Coriolis versus Thermal Mass Flow meters for Gases and Liquids.

  • Fluid independent flow measurement and control - no need for recalibration

  • Gas and liquid can be measured with the same sensor

  • Ability to measure undefined or variable mixtures

  • Suitable for supercritical fluids, e.g. carbon dioxide (CO2) or ethylene (C2H4)

  • Same compact footprint

  • High accuracy ± 0.2% of rate ± zero stability for liquids ± 0.5% of rate ± zero stability for gases

  • Large turndown range of up to 1:2000

  • Fast sensor response time: down to 50…100 msec
