Abstract:
The Coriolis flowmeter according to the present disclosure includes: a measuring sensor including a bent measuring tube mirror-symmetrical with respect to a transverse plane, wherein a measuring tube center line runs in a longitudinal plane oriented perpendicular to the transverse plane, wherein an equatorial surface runs perpendicular to the longitudinal plane along the measuring tube center line; an exciter for exciting measuring tube bending vibrations; a first pair of vibration sensors for capturing the bending vibrations of the measuring tube; and an operating and evaluation circuit for driving the exciter, for capturing signals from the vibration sensors, and for determining a mass flow measured value, wherein the measuring sensor has a second pair of vibration sensors, which are arranged in a mirror-symmetrical manner with respect to the transverse plane, wherein the first pair of vibration sensors is separated from the second pair of vibration sensors by the equatorial surface.
