An oil burglar alarm device is provided to inform the interception of the oil of a user on a real time basis by detecting the impact applied to the oil and an oil tank. An oil burglar alarm device comprises a flux sensor(120), an alarm sound output part(150) and a controller(110). The flux sensor senses the flow rate of the oil reservoir. The alarm sound output part outputs the warning tone. The controller compares the current flux, and the previously sensed flow rate, once the flow rate of the oil reservoir is inputted from the flux sensor. The controller outputs the warning tone through the alarm sound output part, if the decrement of the oil decreasing rate is greater than an oil treatment reagent critical value. |
