FUEL TANK OF A VEHICLE CONTAINING ONE CAPACITIVE INTERFACE LEVEL SENSOR Russian patent published in 2022 - IPC B60K15/03 B65D90/48 G01F23/26 

FIELD: measuring technology.

SUBSTANCE: invention is intended for measuring the levels of interfaces between media in various industries. The vehicle fuel tank contains a capacitive interface level sensor. The sensor contains a sensitive element, which is a housing for electrodes, which is a metal profile formed by connecting several tubes to each other, containing a stiffening element connecting the adjoining tubes of the profile. Each profile tube contains, on its side adjacent to the measured medium, a slot aligned along the axis with the ventilation hole on the side surface of the collar part. The electrode housing contains electrodes rigidly fixed in each of the profile tubes, which are metal tubes with the same linear capacity, but differing in length, the main electrode being made along the length equal to the length of the electrode housing, and each compensation electrode being made along the length less than the length of the main electrode.

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.
