PURPOSE: To obtain the display of the liquid level in the tank of an automobile while the automobile is run by intermediately storing the measurements of the liquid level at prescribed time intervals and comparing the stored measurements with actual measurements, and then, not displaying the increase of measurements detected by the comparison during running. CONSTITUTION: A device for displaying liquid level in the tank of an automobile is constituted by connecting a liquid level detector 1 to a microcomputer 26 or microprocessor 27, the input side of which is connected to the speed sensor 9 of an automobile, through an A/D converter 23 and a display device 3 to the poststage of the computer 26 or processor 27. The measurements of the liquid level are intermediately stored at prescribed time intervals and, at the same time, compared with actual measurements. While the automobile is run, in addition, the increase of the measurements detected by the comparison is not displayed. Therefore, the apparent increase of the content in the tank while the automobile is run can be prevented, but a filling liquid level indicator which is set when the ignition key of the automobile is turned on and the engine of the automobile is operated indicates the increase of the liquid while the automobile is refueled. |
