The device is used for detecting the liquid level in the oil tank body 1, because the lower communicating pipe 2 is communicated with the lower liquid inlet pipe 4 (the oil tank body 1 and the liquid level meter body 5 form a communicating vessel), the liquid level change in the liquid level meter body 5 is synchronous with the inside of the oil tank body 1, when the oil inlet amount of the oil tank body 1 is larger than the oil discharge amount, the petroleum liquid level in the oil tank body 1 rises, the liquid level of the liquid level meter body 5 rises synchronously, the liquid level drives the stabilizing mechanism 12 to rise, the stabilizing mechanism 12 drives the magnetic ring 13 to rise along the guide rod 11, when the magnetic ring 13 passes through the Hall sensor 601 (the Hall sensor 601 is a linear sensor for detecting the magnetic field size), the Hall sensor 601 detects that the surrounding magnetic field is gradually increased, when the magnetic ring 13 is level with the Hall sensor 601, the magnetic field detected by the Hall sensor 601 is the largest, at the moment, the Hall sensor 601 transmits a signal to the control terminal 10, the control terminal 10 lights the LED lamp beads 701 corresponding to the Hall sensor 601 and passing through the magnetic ring 13, the LED lamp beads 701 are sequentially lighted along with the rise of the magnetic ring 13, at the moment, an operator observes the change of the LED lamp beads 701 to obtain the change of the petroleum liquid level in the oil tank body 1, the liquid level is obtained through the scale marks on the transparent shell 7, the LED lamp beads 701 replace the original magnetic turning plate, the problem that the original magnetic turning plate is exposed to the sun and aged by wind and is not in place to influence the observation of the operator is avoided, in the environment with poor visibility condition, the operator can also observe the change condition of the liquid level in the oil tank body 1 remotely, and the better liquid level observation effect is realized.

If an operator is far away from the site, the change of the petroleum liquid level in the oil tank body 1 can still be obtained through data transmitted by the control terminal 10, and the remote detection effect is realized, when the petroleum liquid level in the oil tank body 1 is lowered, the magnetic ring 13 downwards sequentially passes through the hall sensors 601, the hall sensors 601 transmit signals to the control terminal 10, the control terminal 10 extinguishes the LED lamp beads 701 corresponding to the hall sensors 601 through which the magnetic ring 13 passes, and as the oil tank body 1 is communicated with an oil pipe, the continuous oil entering and exiting can affect the stability of the liquid level in the oil tank body 1, so that the liquid level in the oil tank body 1 fluctuates, therefore, when the liquid level change in the oil tank body 1 does not exceed the distance between the two hall sensors 601 (which proves that the liquid level change in the oil tank body 1 cannot be detected), the distance between the liquid levels of the two hall sensors 601 is determined by the detection precision (both are within the error allowed by the precision, and the detected fluctuation height is an integer, which is convenient for the operator to observe and analyze), the stabilizing mechanism 12 is used for eliminating the liquid level in the liquid level meter body 5, so that the stabilizing mechanism 12 can not drive the magnetic ring 13 to move up and down, thereby avoiding the problem that the hall sensors 601 that the working capacity of the hall sensors 601 is increased due to be detected frequently and the hall sensors 601 is increased, and the problem that the working life of the hall sensors 601 is caused by the hall sensors 601 is increased.

The stabilizing mechanism 12 is used for eliminating the influence of liquid level change on the magnetic ring 13, the liquid level is located in the middle of the magnetic ring 13 and the middle of the buoyancy shell 1201 in the initial state, the buoyancy provided by the floating ball on the magnetic ring 13 enables the magnetic ring 13 and parts (except the buoyancy shell 1201 and the lantern ring 1209) in the stabilizing mechanism 12 to be kept in a stable state, due to the elastic force of the tension spring 1203, the first sliding rod 1202 enables the limit block 1204 to be in contact with the inner wall of the liquid level meter body 5, when the liquid level in the liquid level meter body 5 changes, taking the liquid level rising as an example, the buoyancy borne by the floating ball of the magnetic ring 13 is increased, due to the friction force existing between the limit block 1204 and the liquid level meter body 5, the floating ball cannot drive the magnetic ring 13 to rise, when the liquid level rises, the buoyancy shell 1201 also rises, when the limit ring on the buoyancy shell 1201 is in contact with the upper fixing ring 1205, the limit ring drives the upper fixing ring 1205 to move upwards, the fixing ring 1205 drives the three first sliding rods 1202 to move relatively through the connecting rod 1206, the tension spring 1203 is stretched, meanwhile, the extrusion force between the limiting block 1204 and the inner wall of the liquid level meter body 5 is reduced, the magnetic ring 13 continues to rise under the buoyancy action of the floating ball and the driving of the limiting ring on the buoyancy shell 1201 (in the process, the limiting ring on the buoyancy shell 1201 is always in contact with the fixing ring 1205), when the magnetic ring 13 passes through the hall sensor 601, the hall sensor 601 detects that the surrounding magnetic field is gradually increased, when the magnetic ring 13 is flush with the hall sensor 601, the magnetic field detected by the hall sensor 601 is the largest, at the moment, the hall sensor 601 transmits a signal to the control terminal 10, the control terminal 10 lights the LED lamp beads 701 corresponding to the hall sensor 601 through which the magnetic ring 13 passes, along with the rising of the magnetic ring 13, the LED lamp beads 701 are sequentially lighted, at the moment, an operator obtains the change of the liquid level of the petroleum in the tank body 1 by observing the change of the LED lamp beads 701, when the petroleum liquid level in the oil tank body 1 does not rise any more, the upper limiting ring of the buoyancy shell 1201 does not drive the upper fixing ring 1205 to move upwards any more, the tension spring 1203 resets, the limiting block 1204 extrudes the inner wall of the liquid level meter body 5 again, at this time, the upper limiting ring of the buoyancy shell 1201 contacts the upper fixing ring 1205, when the petroleum liquid level in the oil tank body 1 fluctuates, the upper limiting ring of the buoyancy shell 1201 vibrates upwards and downwards, so that the upper fixing ring 1205 moves upwards for a certain distance (the distance is half of the amplitude of the petroleum liquid level), then, the buoyancy shell 1201 fluctuates along with the liquid level, because the distance between the two fixing rings 1205 is not greater than the distance between the two hall sensors 601, when the liquid level change in the oil tank body 1 does not exceed the distance between the two hall sensors 601 (it is proved that the liquid level change in the oil tank body 1 cannot be detected), the distance between the two hall sensors 601 is determined by detection accuracy (both are within the error allowed by the accuracy, and the detected liquid level height is an integer, which is convenient for an operator to observe and analyze), thereafter, the upper and lower limiting block of the upper and lower limiting ring of the buoyancy shell contacts the fixing ring 1205 with the fixing ring 1205, and meanwhile, because the limiting block 1204 has no influence on the inner wall of the liquid level meter body 5, the magnetic force, the hall sensors 601, the problem that the hall sensor 601 is not increased by the hall sensor 601, the operating pressure is increased, the problem that the operating pressure of the hall sensor 601 is increased frequently, and the hall sensor 601 is avoided, and the hall sensor 601 is increased, and the problem that the operating pressure of the hall sensor 601 is increased frequently, and the hall sensor 601 is increased, and the problem that the operating pressure is increased.

When the liquid level descends, the limit ring of the buoyancy shell 1201 extrudes the lower fixing ring 1205, the limit block 1204 reduces the extrusion force on the inner wall of the liquid level meter body 5, the magnetic ring 13 downwards sequentially passes through the hall sensor 601, the hall sensor 601 transmits signals to the control terminal 10, the control terminal 10 extinguishes the LED lamp beads 701 corresponding to the hall sensor 601 through which the magnetic ring 13 passes, when the liquid level does not descend any more, the magnetic ring 13 is limited again, the limit ring of the buoyancy shell 1201 is in contact with the lower fixing ring 1205, when the petroleum liquid level in the oil tank body 1 fluctuates, the limit ring on the buoyancy shell 1201 vibrates up and down, so that the lower fixing ring 1205 moves down for a certain distance (the distance is half of the amplitude of the petroleum liquid level), subsequently, the buoyancy shell 1201 fluctuates up and down along with the liquid level, because the limit block 1204 has extrusion force on the inner wall of the liquid level meter body 5, the magnetic ring 13 cannot be influenced by the fluctuation of the liquid level.
