ABSTRACT:
A liquid quantity sensing device which can easily and accurately measure liquid quantity stored in a container is disclosed. It utilizes an infrared ray or a supersonic sensing element associated with a float placed in the measuring tube and an electrical circuit board to indicate the measured result on a gage. The information about position of the float detected by the sensing element is inputted into an electrical circuit board as a return signal where it is analyzed and decipherd and then transformed into a value of the liquid quantity to be indicated by a gage. The device is applicable to various sized container by merely adjusting the tube length. An upper and a lower limits of liquid level may be prescribed, a warning signal can be obtained if the liquid level exceeds either limit.
