The present invention relates to a security device for a digital water meter and, more specifically, to a security device for a digital water meter capable of preventing an electric means from being illegally manipulated by sensing separation of a flow rate measuring unit and an electric unit. A digital water meter can reduce human resources required for metering but is not periodically checked by a meterman unlike an existing mechanical metering method. Therefore, the digital water meter requires a means for checking a state of the digital water meter. Specifically, a means for preventing illegal manipulation of the electric unit is essential as a case in which the electric unit is illegally manipulated by being separated from the flow rate measuring unit may occur. The security device for a digital water meter can detect illegal manipulation by detecting the separation of the flow rate measuring unit by having a magnetism detecting unit detecting magnetism of a permanent magnet and sensing ...
