A Coriolis flowmeter (10) vibrates 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 section (50) that calculates fluctuations from a detection signal (SA); status value calculation section (60) that calculates a status value showing a state of air bubbles in the fluid from the fluctuations calculated by the fluctuation calculation section (50), and determination section (70) that determines a state of air bubbles from the status value calculated by the status value calculation section (60). |
