Abstract
A mass flowmeter operating by the Coriolis principle incorporates a straight Coriolis measuring tube through which flows a fluid or medium, at least one oscillator associated with and exciting the Coriolis measuring tube, and at least one detector associated with the Coriolis measuring tube for capturing the Coriolis forces and/or the Coriolis-force-induced oscillations. To provide a Coriolis flowmeter incorporating a Coriolis measuring tube which is subject to only minimal thermal expansion and, accordingly, to only minimal thermal stress, and which is resistant to chemicals, the Coriolis measuring tube is made of a ceramic material.
