DRIVING DEVICE OF CORIOLIS FLOWMETER, AND CORIOLIS FLOWMETER

摘要

PROBLEM TO BE SOLVED: To provide a driving device of a coriolis flowmeter that decreases the cost for manufacturing a magnet unit and efficiently vibrates a pair of flow tubes.SOLUTION: A driving device of a coriolis flowmeter includes a magnet 20, a magnet unit 3, and a coil unit 4. The magnet unit 3 includes: a holding metal fitting 31 mounted with the magnet 20; and a base metal fitting 32 that is mounted with the holding metal fitting 31 and is fixed to a facing surface of one of a pair of flow tubes 12. When the holding metal fitting 31 is mounted on the base metal fitting 32, the magnet unit 3 covers the outer periphery of the magnet 20. The coil unit 4 includes an electromagnetic coil unit 41 having an electromagnetic coil 413, and a coil attachment part 42 fixed to a facing surface of the other of the pair of flow tubes 12.
