PURPOSE: A three dimensional magnetic circuit is provided to facilitate an installing process and a disassembling process without the addition of components and to reduce a cost required for replacing external devices by preventing the malfunction of a water gauge. CONSTITUTION: A three dimensional magnetic circuit includes an upper magnetic part, a lower magnetic part, an upper case(300), a lower case(400), and a pair of sliding bars(510, 520). The magnetic part is arranged on the upper side of a fluid pipe(10) and emits magnetism. The lower magnetic part is arranged at the lower side of the fluid pipe and corresponds to the upper magnetic part. The upper case surrounds the external side of the upper magnetic part. The lower case surrounds the lower magnetic part. The sliding bars surround the lateral side of the magnetic parts and connect the cases. |
