PROBLEM TO BE SOLVED: To provide a liquid level detection system that allows an oil level gauge for measuring an oil amount to be easily installed to or detached from a container and that prevents oil from spilling onto a floor in a large amount when the container falls during oil feeding.SOLUTION: In a liquid level detection system 20 for detecting the amount of waste oil in a container 12, the container 12 has first and second through holes 12a and 12b where first and second internal threads are formed, a hose 10 for transferring the waste oil is fixed to feed the waste oil into the container 12, a coupler 30 where a first external thread 31d screwed to the first internal thread is formed is fixed to the first through hole 12a, and an oil level meter 40 separated into a first block 41 and a second block 42 where the first block 41 and the second block 42 are connected by a union nut 43 is screwed to the second through hole 12b.SELECTED DRAWING: Figure 1 |
