FUEL STORAGE TANK CONTAINING SEVERAL CAPACITIVE INTERFACE LEVEL SENSORS Russian patent published in 2023 - IPC B65D90/48 B65D88/02 G01F23/26 

FIELD: measuring technology.

SUBSTANCE: invention is intended for measuring the levels of interfaces between media in various industries. The fuel storage tank contains several capacitive level sensors of the media interface. Moreover, one of the sensors contains a base and a sensitive element. The base contains the first part containing a niche with a cover for hermetic placement of an electronic computing unit, and a second part, which has holes for embedded bushings in the center in the area of the first part; on the side surface has holes for fasteners and ventilation holes. The sensitive element is a housing for electrodes, which is a metal profile formed by connecting several tubes to each other, containing a stiffening element connecting the profile tubes. In addition, each profile tube contains an air vent located coaxially with the air vent on the side the surface of the collar part; and contains a slot aligned along the axis with the ventilation hole on the side surface of the collar part.

EFFECT: technical result is an increase in the reliability and manufacturability of the design, and, as a result, an increase in the accuracy of measurements of the level of the interface between media.
