Claims

[Scope of utility model registration request]

a fuel tank whose volumetric shape from top to bottom differs in at least a portion; a first fuel sender gauge disposed at a portion of the fuel tank with the smallest liquid level fluctuation point;
a second fuel sender gauge arranged parallel to the fuel tank at a predetermined distance from the fuel sender gauge, and output and liquid level fluctuation of the first fuel sender gauge when the liquid level is stationary; When the liquid level is at such a level that there is no output difference between the output and the current output, the average value of the outputs of the first fuel sender gauge and the second fuel sender gauge is determined in advance based on the volumetric shape of the fuel tank. a first fuel remaining amount calculation means that calculates the remaining fuel amount by substituting it into a first arithmetic expression stored in memory; and an output of the first fuel sender gauge when the liquid level is stationary and an output when the liquid level is fluctuating. The output difference between the first fuel sender gauge and the second fuel sender gauge and the average value of both sender gauges are set in advance to the volumetric shape of the fuel tank. 2. A fuel remaining amount measuring device comprising: second fuel remaining amount calculating means for calculating the remaining fuel amount by substituting the second arithmetic expression stored in the memory based on the second arithmetic expression.
