The cavity has a longitudinal axis and serves to accommodate a liquid, and the level device body is arranged in a carrier body. The carrier body includes two transparent covers for closing the carrier body and preferably includes a casing body which is preferably in the form of a circular ring. An outside wall of the level device body has a curved region with a curvature in the longitudinal direction relative to the longitudinal axis of the cavity, by which a magnifying glass effect can be achieved when viewing a marker body which can be arranged in the cavity."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Level device","description":"A level device for a spirit level includes a level device body, and a substantially cylindrical cavity formed by an inside wall of the level device body.
