Abstract
A Coriolis flowmetervibrates a measurement tube through which a fluid subject to measurement flows, detects vibrations including Coriolis force developed in the fluid from the vibrations, and measures a mass flow rate of the fluid from a detection signal. The Coriolis flowmeter is characterized by including fluctuation calculation sectionthat calculates fluctuations from a detection signal SA; status value calculation sectionthat calculates a status value showing a state of air bubbles in the fluid from the fluctuations calculated by the fluctuation calculation section, and determination sectionthat determines a state of air bubbles from the status value calculated by the status value calculation section
