LIQUID AMOUNT MEASURING DEVICE

摘要

A liquid amount measuring device 10 includes a plurality of detectors 36, 22 arranged within a vessel, each of the plurality of detectors being configured to output a first analog signal, and an output circuit 38 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 detectors. Each of the detectors 36, 22 includes a float 24, 32; an arm member 26, 34 configured to convert a vertical motion of the float 24, 32 to a rotational motion; and a magnetic sensor 31, 41 configured to output a second analog signal corresponding to the rotational motion of the arm member. The output circuit 38 is configured to correct the first analog signals outputted from the detectors 22, 36 and add the corrected first analog signals so as to output the analog detection signal.
