When the oil tank floating oil outlet device is used, the oil tank can not be used for oil, and oil supply of an airport is interrupted due to the fact that the head of the oil tank is warped and the oil outlet floats out of the liquid level due to the fact that air is stored in the oil tank and the rotary joint is clamped and stuck. Therefore, a great deal of research is carried out on the monitoring of the running state of the oil tank floating oil outlet device at home and abroad, and a plurality of monitoring methods are put forward in combination with practical use. The domestic research of monitoring the operating condition of the floating oil production device begins in the ninth decade of the last century and is mainly detected by visual inspection, rope inspection and a floating pipe indicator:
(1) visual inspection: the state of the floating oil outlet device is visually observed through the lighting hole. When the floating oil outlet device stops oil sending operation, a worker opens a blind plate of a lighting hole at the top of the tank, and the approximate position of a floater of the floating oil outlet device is visually observed through the lighting hole to judge whether the working state of the floating oil outlet device is normal.

This method requires careful design and installation to prevent the inspection line from tangling and interfering with the branch pipes and other equipment inside the tank.
(3) A floating pipe indicator: the floating pipe indicator is only suitable for a single-arm oil tank floating oil outlet device and is not suitable for a double-arm or multi-arm floating oil outlet device. The working height of the floating pipe is indicated according to the angle change of the rotary joint so as to display whether the floating pipe works normally or not and to display whether the floating pipe is lifted or lowered. The float tube indicator is a mechanical indicator. The floating pipe indicator is arranged on the pipe wall or the tank top and is connected with a rotary joint in the tank through a steel wire rope, and the floating pipe indicator can only display the approximate position of the working height of the floating pipe and judge whether the floating pipe is in a working state or not. The device can not monitor the dynamic influence of oil density, floating pipe air intake and the like on the stress of the top end of the floating pipe, has the functions of fault early warning judgment and the like, and does not have the foundation of signal imaging, data remote transmission and linkage control of valve opening and closing and pump starting and stopping.
