Abstract
A vibrating-tube fluid measurement device includes a tube, a base block, a magnet which applies a magnetic field to the tube, an excitation source which generates vibration of the tube, a vibration sensor which measures a signal corresponding to a vibration frequency of the tube, and an electrical isolator formed of glass, wherein the vibrating tube is mounted to a base block via the electrical isolator and electrically isolated from the base block via the electrical isolator.
