ABSTRACT:
A non-contact type sensor that measures a liquid level in a non-contact fashion and outputs a measured value as a digital pulse is provided. Then, a sensor-output converting circuit is caused to input the digital pulse, which is output from the non-contact type sensor, into an existing central processing unit as an analogue voltage that corresponds to a duty factor of the digital pulse.
