Description

Technical Field

[0001] The invention discloses a displacement switching device for a liquid level meter, belonging to the field of liquid level meters. Background Art

[0002] The connected level gauge is based on the principle of connected vessels, and directly displays the liquid level height in the container through a transparent pipe or cavity. This type of level gauge has the characteristics of simple structure, easy use, low maintenance cost and high reliability, and is suitable for a variety of working environments and conditions. During installation, it is usually necessary to drill holes on the wall of the liquid storage container and ensure that the surface of the contact surface between the container wall and the level gauge is smooth to ensure a good sealing effect. After the drilling process on the wall of the liquid storage container is completed, the installation position of the level gauge is also fixed. The fluctuation of the liquid level, the difficulty in accurately measuring the liquid level, and the possibility that the liquid may remain on the cavity wall or other components or temporarily suspended in the air in some equipment may all lead to errors in the liquid level measurement. The level gauge usually has a fixed range. The above problems may cause the actual liquid level to exceed the measurement range of the level gauge. Once the installation position of the level gauge is determined and processed, it cannot be adjusted, resulting in the holes drilled on the wall of the liquid storage container being unusable.
