Description

Technical Field

[0001] The utility model relates to the technical field of liquid level gauges, and more specifically to an antifreeze magnetic flap liquid level gauge. Background Art

[0002] The magnetic flap level gauge is a common liquid level measuring instrument used to measure the liquid level in the liquid. It is mainly composed of a magnetic flap, a float, a sensor, etc., and determines the liquid level by measuring the position change of the magnetic flap.

[0003] In a magnetic flap level gauge, one or more magnetic bodies, usually one or more small magnets, are attached to the magnetic flap. The float floats on the surface of the liquid and moves up and down with the rise and fall of the liquid level. When the liquid level rises, the float also rises, driving the magnetic flap to flip. When the liquid level drops, the float drops and the magnetic flap returns to its original position.

[0004] Magnetic flap level gauges can be used to detect the liquid level of media in various towers, tanks, tanks, spherical containers, boilers and other equipment. However, when using magnetic flap level gauges in cold areas or cold places, their main bodies are exposed to the cold environment and are prone to freezing and crystallization, and even main body explosion accidents, which will have a great impact on data reading and display.
