LEVEL OF LIQUID SIGNALING DEVICE Russian patent published in 2007 - IPC G01F23/38 

FIELD: inspection and regulation of level of liquid.

SUBSTANCE: level of liquid signaling device has float, magnet mounted on float, lever made for turn around horizontal hinge, float's stroke restrictor and reed mounted for being switched from magnet related to lever. No less than three magnets are related with lever. Magnets are magnetized at the same direction and they are remote from axis of hinge and are mounted with angular shift relative each other. The shift provides continuous area of interaction of float with reed. Moreover float is made rotating and it is integrated with lever into single structure element; as the lever of the second kind is used. Axis of hinge is parallel to axis of magnetization of magnet tightly connected with end of lever, and to axes of reeds mounted for in-turn entry off float into interaction with them and for simultaneous interaction with at least two reeds and as well at situation when float makes contact with restrictor and the interaction is performed with single reed only.

EFFECT: widened functional abilities; widened area of application; reduced sizes; simplified design; improved precision; higher reliability of alarm.
