ABSTRACT:
There is provided a Coriolis mass flowmeter. The flowmeter is configured to vibrate a pipe line through which a fluid flows and measure a mass flow rate of the fluid flowing through the pipe line, based on a phase difference between an upstream vibration signal and a downstream vibration signal, wherein the upstream vibration signal is detected in an upstream side of the pipe line, and the downstream vibration signal is detected in a downstream side of the pipe line.
