Description

Technical Field

[0001] The utility model relates to the technical field of liquid level monitoring, and more specifically, to a magnetic flap liquid level alarm switch with an audible and visual alarm light. Background Art

[0002] The magnetic flap level gauge is developed based on the principle of buoyancy and magnetic coupling. When the liquid level in the measured container rises or falls, the magnetic float in the level gauge body tube 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. When the liquid level rises, the flip column changes from white to red, and when the liquid level drops, the flip column changes from red to white. The red and white intersection of the indicator is the actual height of the liquid level inside the container, thus achieving clear indication of the liquid level. The magnetic flap level gauge can be used for medium liquid level detection in various towers, tanks, tanks, spherical containers, boilers and other equipment.
