A device for measuring instantaneous flux in water gauge is provided to improve watertightness of a PCB by preventing resin from draining with an external magnetic cut-off ring surrounding a PCB. A device for measuring instantaneous flux in water gauge includes a disk-shaped PCB consisted of multiple sensors(11) arranged radially. An external magnetic force cut-off ring(20) blocking the unnecessary magnetic force is installed at the outer circumference of the PCB. The external magnetic force cut-off ring prevent flooding of resin when pouring water sealing resin into the PCB and then solidifying it. The heating seat(30), which prevents escape before the sealing resin is solidified, is formed in the lower part of the external magnetic force cut-off ring and the PCB. |
