Title: Improvements in indicator for showing the level of a liquid in a reservoir
IPC: G01F23/36
Filed: 1940-04-29
Abstract: 542,360. Indicating. FABRICA ITALIANA MAGNETI MARELLI. April 29, 1940, No. 7638. Convention date, May 2, 1939. [Class 106 (iv)] In a liquid-level indicator comprising a screen on which a shadow is projected by a vane moved by a member responsive to the liquid level, the screen provides a vertical indicating dial of a height corresponding to that of the container, and the shadow and illuminated zones correspond respectively to the portion occupied by the liquid and the empty portion of the container. In the instrument shown, an insulating former 11 carries two mutually perpendicular electrical windings 1, 2 the resultant field of which acts on an armature 6 pivotally mounted in a recess in the former and carrying a vane 7 the shadow of which is thrown on to a translucent screen 19 by a lamp 8. The current in the winding 2 is controlled by an adjustable resistance the movable contact of which is operated by means, 'for example a float, controlled by the level of the liquid. The current in the winding 1 is not varied, so that the position of the vane, and the height of the shadow thrown by it on the screen 19, corresponds to the level of the liquid. The contour of the dial, formed by an aperture in an opaque screen 17, is preferably such that the shadowed zone has an area proportional to the capacity of the portion of the container occupied by the liquid, and the contour may correspond to a vertical cross-section of the container as shown in Fig. 5 for one of triangular cross-section.
