PURPOSE:To facilitate molding process, uniformize flux density, and improve measuring accuracy, by laminating a plurality of insulated sheets provided with print-circuited spiral conductive circuits and arranging magnetic flux deflecting boards made of ferromagnetic foils on their outside. CONSTITUTION:On the outside of exciting coils 10 constructed by lamination of a plurality of flexible insulating sheets 8 of print-circuited spiral conductive circuit 7, are located magnetic flux deflecting boards 12 constructed by lamination of a plurality of amorphous alloy foils 11, as ferromagnetic foils. By this arrangement, appropriate magnetic flux flow between both exciting coils 10, 10 and especially, flow outside of the measuring pipe 1 can be assured resulting to a higher measuring accuracy and easier molding process. |
