Description

Technical Field

[0001] The utility model relates to the technical field of installation of magnetic flap liquid level gauges, and specifically relates to a magnetic flap liquid level gauge limit device. Background Art

[0002] The magnetic flap level gauge is an instrument widely used in various liquid level measurement fields. It uses the magnetic material inside the display unit to display the corresponding color changes as the liquid level rises or falls, thereby informing the specific position of the liquid. It is suitable for measuring the level of various liquids, such as oil, water, acid, alkali and other corrosive media. It has high measurement accuracy and stability, and can meet the use requirements of various industrial sites. The magnetic flap level gauge has an intuitive display interface, simple and convenient operation, and easy maintenance.

[0003] During the installation and limiting process of the magnetic flap level gauge, if the installation position of the magnetic flap level gauge is inaccurate, the level gauge may not correctly display the actual position of the liquid level, thus affecting the monitoring of the production process. Moreover, if the fixation is not firm, the level gauge may also fall off due to external forces such as vibration and pressure during the production process, thus affecting the monitoring of the liquid level. Therefore, we propose a magnetic flap level gauge limit device to ensure that the magnetic flap level gauge is firmly fixed when installing it. Utility Model Content
