PROBLEM TO BE SOLVED: To dispense with troublesome regulation of a resonance frequency for two sensor tubes, and to secure stable vibration of the sensor tubes. SOLUTION: A support column 5 is arranged between the two sensor tubes 3, 4 with a fluid to be measured, and the support column 5 is attached with a magnet 12 of an exciter 6 for vibrating the two sensor tubes 3, 4 along directions approached and separated each other, a magnet 14 of flow-in side pick-ups 7 and flow-out side pick-ups 8 for detecting a relative displacement between the two sensor tubes 3, 4. Vibrational strains in the two sensor tubes 3, 4 are reduced more than those in attaching the magnets 12, 14 onto the two sensor tubes 3, 4, because only coils 11, 13 are attached to the sensor tubes 3, 4 and measurement precision is enhanced thereby by the extent corresponding thereto.
