The meter (1) has gradient coil (5) and signal coil (6) that are arranged between measuring tube (3) and magnetization unit (4) in magnetic field permeated space (15). Coil suspensions (16,17) are formed between coil bobbin (7) and ends (10,11), respectively. A top surface (18) of coil bobbin in position (19) between coil suspensions (16,17) is closed surface. The coil bobbin is sealed with ends (10,11) of housing (8), by coil suspensions (16,17), respectively. The housing is sealed together with coil bobbin and coil suspensions (16,17). The meter has magnetization unit that generates magnetic field through measuring tube. The gradient coil generates gradient in magnetic field, and signal coil detects effect of excitation of coil bobbin and housing. The housing is provided with ends (10,11) along longitudinal axis (9) of measuring tube. Housing openings (12,13) are formed in ends, respectively. The magnetization device is provided in interior portion (14) of housing. The gradient coil and signal coil are arranged on coil bobbin. |
