Liquid amount measuring device

A liquid amount measuring device, comprising:

• a plurality of detectors arranged within a vessel, wherein each of the plurality of detectors is configured to output a first analog signal;
• an output circuit configured to output an analog detection signal corresponding to an amount of the liquid stored in the vessel based on the first analog signals outputted by the plurality of detectors;
• and
• correction circuits, each of which is provided to each of the detectors and arranged between the corresponding detector and the output circuit, wherein each correction circuit is configured to correct the first analog signal outputted by the corresponding detector and output the corrected first analog signal to the output circuit,
• wherein each of the detectors includes a float;
• an arm member configured to convert a vertical motion of the float to a rotational motion;
• and a magnetic sensor configured to output a second analog signal corresponding to the rotational motion of the arm member,
• each of the detectors is configured to output the first analog signal based on the second analog signal, and,
• the corrected first analog signals outputted from the correction circuits are inputted to the output circuit, and the output circuit outputs the analog detection signal corresponding to the amount of the liquid stored in the vessel based on the corrected first analog signals that were inputted.
