この発明は液面計に係り更に詳述すればマグネット式の
液面計に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid level gauge, and more particularly to a magnetic type liquid level gauge.
液面計を構成するフロートと液面位置を表示するロータ

を知るために好都合である。A liquid level gauge with magnets attached to both the float that makes up the liquid level gauge and the rotor that displays the liquid level position can display the liquid level position of liquids that are structurally isolated from the outside using magnetic force as a medium. However, it is convenient for knowing the liquid level position of liquids having high pressure, explosive, flammable, and toxic properties (temperatures below the Curie point of the magnet).
この種マグネット式の液面計は古くから種々の構造のも

えた０ことを特徴とする液面計を提供するものである。For example, the liquid level gauge described in Tokukan Sho 52-96052 has a structure in which a magnet is embedded in the center of the rotor when the rotor is formed by casting, so it is difficult to manufacture. This method has disadvantages in that it takes a long time, lacks productivity, and is troublesome to assemble because the row outer support shaft is attached from outside the lotus body. The purpose of this invention is to eliminate the above-mentioned drawbacks of the conventional art.A circular magnet arranged diametrically is housed in the bottom of a cylindrical float container concentrically with the magnet. A plurality of rotation indicators each having a different display on each half of the circumferential surface with a line perpendicular to the magnetization direction on the outer periphery are mounted on a single support member capable of providing a means for regulating the mounting interval, and are mounted inside the housing. The rotation indicator is installed vertically in the cliff body at a regulated interval, the rotation indicator is suspended by filling liquid in the sparrow body, and the rotation indicator is placed on a float provided in the cliff body. The present invention provides a liquid level gauge characterized in that it is equipped with a magnet body magnetized in the height direction of the body.
