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

FIELD: measuring equipment.

SUBSTANCE: invention is intended for measurement of medium interface levels in different industries. A fuel storage tank contains several capacitive sensors of a medium interface level. The sensor contains a sensitive element, which is a case for electrodes, which is a metal profile formed by connection of several tubes to each other, containing a rigidity element connecting bordering tubes of the profile. Each tube of the profile contains a ventilation hole placed coaxially with a corresponding ventilation hole on a side surface of a collar part and contains, on its side bordering with the measured medium, a slot combined with the ventilation hole on the side surface of the collar part. The case for electrodes contains, in each tube of the profile, electrodes, which are metal tubes having the same linear capacity, but different in length, wherein the main electrode is made along a length equal to a length of the case, and each compensation electrode is made along a length smaller than the length of the main electrode.

EFFECT: increase in the reliability and manufacturability of a structure and, consequently, increase in the accuracy of measurements of a medium interface level.
