ABSTRACT:
A Coriolis flowmeter includes an oscillator for oscillating a fluid pipe that forms a flow path for allowing a measurement fluid to flow; first and second detectors that are disposed to be spaced apart from each other along the flow path of the fluid pipe so as to detect a state of oscillation of the fluid pipe; and a calculator for calculating a mass flow rate of the measurement fluid that passes through the flow path of the fluid pipe on the basis of a relative amount of the states of oscillation that are detected by the first and second detectors. The fluid pipe includes an inner pipe made of a fluororesin whose inner circumferential surface is in contact with the flow path, and an outer pipe having fibers that are arranged in order to surround an outer circumferential surface of the inner pipe and a resin that is cured in a state of close adhesion between the fibers arranged in order, and having an elastic modulus larger than that of the inner pipe.
