Description

Technical Field

[0001] The utility model relates to the technical field of magnetic flap liquid level gauges, in particular to a magnetic flap type liquid level gauge. Background Art

[0002] The magnetic flap level gauge is developed based on the buoyancy principle and magnetic coupling. When the liquid level in the measured container rises or falls, the magnetic float in the main tube of the level gauge also rises or falls. The permanent magnet in the float is transmitted to the magnetic flip column indicator through magnetic coupling, driving the red and white flip columns to flip 180°. When the liquid level rises, the white color in the flip column turns to red, and when the liquid level drops, the red color in the flip column turns to white. The actual height of the liquid level inside the container is outside the red and white boundary of the indicator, thereby achieving a clear indication of the liquid level. That is, the magnetic flap level gauge can be used directly to observe the liquid level height of the medium in various containers, and is suitable for level indication in industrial fields such as petroleum and chemical industry.

[0003] A Chinese patent discloses a magnetic flap type liquid level gauge (authorization announcement number CN218297326U). The patented technology first docks the clamp ring at the bottom end of the screw, and then starts the motor. The motor drives the clamp ring to rotate in conjunction with the screw. When the measuring medium enters the interior of the liquid level gauge body, the magnetic float floats while the screw drives the scraper to rotate up and down. At the same time, the scraper outside the scraper scrapes off the residue on the inner wall of the liquid level gauge body, thereby avoiding the situation where the magnetic float is blocked from moving up and down due to the agglomeration of residues inside the liquid level gauge body, thereby improving the smoothness and stability of the measurement of the device.

[0004] However, there are still some shortcomings in this patent. Although this patent can realize the scraping treatment of the inner wall of the liquid level meter, it can be seen from the drawings of this patent that this patent cannot heat the liquid level meter, which will cause the liquid inside the liquid level meter to freeze in cold weather, thereby affecting the use of the liquid level meter. Therefore, those skilled in the art provide a magnetic flap liquid level meter to solve the problems raised in the above background technology. Utility Model Content
