FIELD: measurement of liquid level in reservoirs. SUBSTANCE: level gauge has a built-up cylindrical case with a measuring scale on the external surface, device for setting and determining of corrections in the form of a ball with measuring scales applied on the external surface in two mutually perpendicular planes, installed on the level gauge case for fixed movement; the ball is placed in a hollow housing with inspection holes and permanent magnets. EFFECT: improved design. 1 dwg
