Description
Technical Field
[0001] This utility model relates to the technical field of magnetic float level transmitters, and in particular to a modular magnetic float level transmitter. Background Technology
[0002] A magnetic float level gauge includes a tube containing a float, which is connected to a container via a flange or other interface to form a communicating vessel. A flip-column display is mounted on the outside of the tube, and a magnet is installed inside the float. The flip-column display contains a cylinder composed of two semi-cylinders, one red and one white. When the magnet and the float rise and fall with the liquid level, their magnetism is transmitted through the tube to the flip-column display, causing the cylinder to flip and thus displaying the liquid level.
[0003] Traditional magnetic level gauge transmitters typically use a single, fixed-length measuring element connected to the main tube. This makes it impossible to replace or combine measuring elements of different lengths, causing significant inconvenience and increasing operating costs in various applications. Utility Model Content
