Abstract
A liquid amount measuring deviceincludes a plurality of detectorsarranged within a vessel, each of the plurality of detectors being configured to output a first analog signal, and an output circuitconfigured 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 detectors. Each of the detectorsincludes a float; an arm memberconfigured to convert a vertical motion of the floatto a rotational motion; and a magnetic sensorconfigured to output a second analog signal corresponding to the rotational motion of the arm member. The output circuitis configured to correct the first analog signals outputted from the detectorsand add the corrected first analog signals so as to output the analog detection signal.
