[0032] During use, the liquid level meter body 1 is used to measure the water level of the liquid in nature or in a container. The bottom communicating vessel 2 fixedly arranged on the liquid level meter body 1 is used to load and connect the bottom communicating pipe 3. The top communicating vessel 5 fixedly arranged on the liquid level meter body 1 and at one end away from the bottom communicating vessel 2 is used to load and connect the top communicating pipe 6. The top sealing ring 9 and the bottom sealing ring 10 sequentially installed on the inner side of the liquid level meter body 1 are used to load and limit the evacuation pipe 8 to ensure the stability of the evacuation pipe 8. The evacuation pipe 8 fixedly arranged on the inner side of the bottom sealing ring 10 is used to divert the liquid inside the liquid level meter body 1. The sealing connection seat 18 fixedly arranged at the bottom of the bottom communicating vessel 2 is used to seal the bottom communicating vessel 2 on the one hand to prevent the liquid in the liquid level meter body 1 and the bottom communicating vessel 2 from overflowing. On the other hand, it is used to cooperate with the loading of the center rod 15. During the rotation of the center rod 15, the sealing effect of the bottom communicating vessel 2 can also be ensured. The motor 19 fixedly arranged on the outer side of the sealing connection seat 18 is used to drive the center rod 15 to rotate on the inner side of the liquid level meter body 1 The central rod 15 fixedly installed on the inner side of the sealing connection seat 18 extending from the output end of the motor 19 is used to load the connecting sleeve 20, and the connecting sleeve 20 plugged on the central rod 15 is used to load the connecting arm 21. The multiple connecting arms 21 fixedly arranged on the connecting sleeve 20 are used to receive the connecting sleeve 20 and the corresponding defoamers 22. The defoamers 22 fixedly installed on the connecting arms 21, under the drive of the motor 19, the motor 19 drives the central rod 15 to rotate, the central rod 15 drives the connecting sleeve 20 to rotate together, and the connecting sleeve 20 drives the connecting sleeve 20 to rotate.

The sliding groove 23 symmetrically opened on the center rod 15 and located between the first limit seat 16 and the second limit seat 17 cooperates with the sliding bar 24 to ensure that the center rod 15 can drive the connecting sleeve 20 to rotate while being able to be raised or lowered, so as to achieve the reduction of bubbles in the water.

The water flows into the inner side of the defoamer 22 through the rotation of the defoamer 22. Since one end of the opening of the defoamer 22 is large and the other end is small, the bubbles in the liquid in the liquid level meter body 1 are gathered and reduced under the action of stress, thereby eliminating the bubbles in the liquid.

[0037] Further, such as Figure 6 As shown, a bearing 14 is sleeved on the top of the center rod 15, and a limit plate 12 is fixedly installed on the outer side of the bearing 14, and the limit plate 12 is connected to the evacuation pipe 8;

[0041] Further, such as Figure 4 As shown, a plurality of evacuation holes 11 are provided on the evacuation pipe 8, and the evacuation holes 11 are arranged in a ring shape on the evacuation pipe 8;

[0042] During use, the multiple evacuation holes 11 opened on the evacuation pipe 8 are used for automatic circulation between the liquid inside the level meter body 1 and the evacuation pipe 8, and the liquid level is displayed in conjunction with the level meter body 1. Since the evacuation holes 11 are located on the evacuation pipe 8 and are distributed in a ring shape, the liquid in the level meter body 1 is more evenly dispersed.

[0043] Further, such as Figure 3 As shown, a bottom communicating vessel 2 is fixedly connected to a bottom communicating pipe 3, and a first solenoid valve 4 is fixedly arranged on the bottom communicating pipe 3;

[0045] Further, such as Figure 2 As shown, a top communicating vessel 5 is fixedly connected to a top communicating pipe 6, and a second solenoid valve 7 is fixedly arranged on the top communicating pipe 6;

[0046] During use, the top connecting pipe 6 fixedly connected to the top connecting vessel 5 is used for the other discharge in the liquid level meter body 1, and the second solenoid valve 7 fixedly arranged on the top connecting pipe 6 is used to control when the gas in the liquid level meter body 1 is discharged.

[0047] Further, such as Figure 2 As shown, the material of the level meter body 1 and the evacuation pipe 8 are both glass;

[0048] During use, since the liquid level meter body 1 and the evacuation pipe 8 are both made of glass, the user can intuitively observe the liquid level in the liquid level meter body 1 .
