Abstract
A measuring system includes a vibration-type transducer including a tube and measuring system electronics electrically coupled to a vibration exciter and a sensor assembly, wherein at a drive point, the vibration exciter is positioned such that a drive offset is no more than 3 mm and/or less than 0.5% of the tube length, and wherein a vibration node of a second or higher order, lies within the reference cross-sectional area, and wherein the measuring system electronics is configured to both provide a drive signal with a sinusoidal current having a frequency such that the frequency deviates from a resonant frequency of a vibration mode of a second order naturally intrinsic to the tube by less than 1% of the resonant frequency and/or by less than 1 Hz, and to perform a self-diagnosis of the measuring system based on a corresponding signal component of at least one vibration measurement signal.
