<P>PROBLEM TO BE SOLVED: To provide a liquid feeding apparatus that can stop liquid feeding when water is mixed in a fuel oil. <P>SOLUTION: A water detecting means 4 is provided in an underground tank type oil feeding apparatus 1, and the water mixed in the oil such as the fuel oil is separated to detect the quantity of the water by a water level sensor. A water detecting circuit which makes the water level quantity into a signal and transmits it, is provided, and the output signal from the water level detecting circuit is compared with the data stored in a memory means to perform a determination on the existence of abnormality. When it is determined to be abnormal, a fuel feeding motor is automatically stopped by a quantity measuring and controlling apparatus. <P>COPYRIGHT: (C)2013,JPO&INPIT |
