PROBLEM TO BE SOLVED: To provide a liquid volume detection device capable of suppressing the total number of connection lines in a structure which detects a total liquid volume reserved in a plurality of reservoirs using a plurality of magnetic sensor type detectors.SOLUTION: A fuel volume detection device 10 includes: first and second fuel volume detectors 36, 22 arranged in reservoirs 14, 16 respectively and a connection line 47. The first fuel volume detector 36 includes: a float 32; an arm member 34; a magnetic sensor for generating a first analogue signal; and an output terminal 45c for outputting a first output voltage value and connected with one end of the connection line 47. The second fuel volume detector 22 includes: a float 24; an arm member 26; a magnetic sensor for generating a second analogue signal; a reference terminal 35b connected with the other end of the connection line 47; and an output terminal 35c for outputting a second output voltage value corresponding to an integrated voltage value integrated with the voltage value shown by the second analogue signal and the first output voltage value. |
