摘要： A portable liquid level detector. The detector comprises a portable casing, a power supply unit disposed in the portable casing, a sensing device coupled to the power supply unit to sense a capacitance within a container and to output a enable signal when a difference in the capacitance is detected, a light emission device coupled to the sensing unit that illuminates after receiving the enable signal, and an alarm device coupled to the sensing unit that sounds after receiving the enable signal.
