The sealing cylinder 211 is slidably installed inside the measuring cylinder 101. The diameter of the outer wall of the sealing cylinder 211 is equal to the inner diameter of the measuring cylinder 101. A limiting cap 210 is fixedly installed on one side of the mounting rod 207.

[0028] The specific implementation method is as follows: through the cooperation between the installation buckle 113, the second slide bar 114, and the pull buckle 115, the staff can pull the pull buckle 115 to drive the second slide bar 114 to move, and then hook the bottom of the float 103 through the pull buckle 115 to remove the float 103 from the bottom of the measuring cylinder 101;

[0029] The liquid level is roughly displayed through the cooperation between the float 103, the first slide bar 102, the permanent magnet 104, the magnetic flip display 105, and the scale mark 106. The measurement reading is accurately displayed through the liquid crystal display 107. The communication module 108 allows the staff to remotely monitor the liquid level.

The measuring tube 101 is connected to the container to be measured through the connecting tube 110, and the opening and closing of the internal channel of the connecting tube 110 is controlled by the valve 111.

[0030] Working principle: When the liquid level meter is used, the cooperation among the snap ring 203, the guide groove 206, the mounting rod 207, the tongue 208 and the first spring 209 makes the sealing cap 202 move toward the bottom of the mounting block 201, and the tongue 208 can be stuck in the bottom of the snap ring 203, thereby fixing the sealing cylinder 211 to the inside of the measuring cylinder 101 to complete the seal. When it needs to be disassembled, it is only necessary to press the sealing cap 202 downward so that the tongue 208 moves to the bottom of the sliding sleeve 205 under the action of the guide groove 206 at the top of the sliding sleeve 205, and then release the second spring 213 to drive the sealing cap 202 to move downward, so that the tongue 208 drives the sliding sleeve 205 to move upward. When the sliding sleeve 205 is close to the bottom of the snap ring 203, the tongue 208 can pass over the snap ring 203 under the action of the guide groove 206 at the bottom of the sliding sleeve 205 to complete the unlocking.

[0031] During the above process, the second spring 213 provides an upward elastic force for the sealing cap 202 to ensure the locking relationship between the tongue 208 and the snap ring 203. The limiting cap 210 limits the displacement distance of the mounting rod 207 and the tongue 208. The sealing ring 212 ensures the seal between the sealing cylinder 211 and the measuring cylinder 101.

[0032] The cooperation between the mounting buckle 113, the second slide bar 114, and the pull buckle 115 allows the operator to pull the pull buckle 115 to move the second slide bar 114, and then hook the bottom of the float 103 through the pull buckle 115 to remove the float 103 from the bottom of the measuring cylinder 101.

[0033] The liquid level is roughly displayed through the cooperation between the float 103, the first slide bar 102, the permanent magnet 104, the magnetic flap display 105, and the scale mark 106. The measurement reading is accurately displayed through the liquid crystal display 107. The communication module 108 allows the staff to remotely monitor the liquid level. The auxiliary light 109 illuminates the magnetic flap display 105 and the auxiliary light 109, making it convenient for the staff to observe the reading in a poorly lit environment. The measuring tube 101 is connected to the container to be measured through the connecting tube 110, and the opening and closing of the internal channel of the connecting tube 110 is controlled by the valve 111.

[0034] The sediment or impurities accumulated inside the magnetic flap level gauge are regularly discharged through the drain valve 112 to keep the inside of the level gauge clean, and the displacement distance of the float 103 is limited by the limit spring 3, and the impact force when the float 103 is displaced is absorbed to prevent the float 103 from rapidly over-displacing and directly hitting the bottom of the measuring tube 101 and the sealing tube 211 to cause damage.
