A review of the theory of Coriolis flowmeter measurement errors due to entrained particles

• We review the “bubble theory” which describes Coriolis flowmeter measurement errors due to entrained particles.
• We include results of previously unpublished work.
• We provide three examples to illustrate the consequences of the theory.

Coriolis flowmeters operate with high accuracy when the medium metered is a single-phase incompressible fluid. Multi-phase fluids lead to measurement errors because of center-of-mass motion. In this paper we review the “bubble theory” which describes errors due to phase decoupling of two-phase fluids. Examples are provided with combined phase decoupling and compressibility errors.
