摘要
A liquid level meter includes a first resistive temperature detector; a first temperature measuring body a liquid level detection section a temperature detection section detecting the temperatures of the first resistive temperature detector and the first temperature measuring body; a current control section determining a value of a current to apply to the first resistive temperature detector such that a difference between the temperatures of the first resistive temperature detector and the first temperature measuring body detected by the temperature detection section to be a first constant value; and a power supply unit supplying a current of the determined current value to the first resistive temperature detector; wherein the liquid level detection section determines whether the first resistive temperature detector is present in a liquid or outside of the liquid using the value of the current applied to the first resistive temperature detector.
