Abstract
The present invention provides a method of outputting a level of a capacitive level sensor which may be provided in a water trap of a fuel cell system and the method of outputting a level of a capacitive level sensor including a level sensor including a plurality of electrodes for measuring capacitance, and an upper electrode and a lower electrode which are able to be disposed adjacent to each other in the level sensor, including: (a) measuring a change in an output value of the lower electrode; and (b) measuring a change in an output value of the upper electrode.
