TANK FOR FUEL TRANSPORT, CONTAINING SEVERAL CAPACITIVE INTERFACE LEVEL SENSORS Russian patent published in 2022 - IPC B65D90/48 B65D88/02 G01F23/26 

FIELD: measuring.

SUBSTANCE: invention is intended for measuring the levels of interfaces between media in various industries. The tank for transporting fuel contains several capacitive level sensors of the media interface. 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 stiffener connecting the tubes of the profile. Each profile tube contains a ventilation hole located coaxially with the ventilation hole on the side surface of the collar part, and contains on its side adjacent to the measured medium a slot aligned along the axis with collar vent. The electrode housing contains electrodes 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 is made along the length less than length of the main electrode.

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