The present invention relates to a device for monitoring a liquid level of a liquid storage tank for a vehicle which increases sensing sensitivity of a liquid level sensor by improving a structure to be able to amplify an electromotive force generated by a liquid sensor at an electrode in an electromotive force amplification layer including a carbon micro coil and which can perform a heating function to solve a freezing state of a liquid by accurately detecting a freezing state of the liquid. The present invention comprises a liquid level sensor, a signal conversion part, and a controller.
본 발명은 액위센서를 전극에서 발생하는 기전력을 카본 마이크로 코일을 포함하는 기전력 증폭층에서 증폭시킬 수 있는 구조로 개선하여 액위 센서의 센싱 감도를 향상시킬 수 있고, 액체의 빙결 상태를 정확하게 감지하여 액체의 빙결 상태 해소를 위한 히팅 기능을 수행할 수 있도록 한 차량용 액체 저장탱크의 액위 모니터링 장치을 제공하고자 한 것이다.
