FUEL STORAGE TANK CONTAINING SEVERAL CAPACITIVE MEDIUM INTERFACE LEVEL SENSORS Russian patent published in 2022 - IPC G01F23/26 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measuring equipment and is intended for measuring the media interface levels in various branches of industry. Container for transporting fuel comprises multiple capacitance sensors of the media interface level. Each one of said sensors comprises a sensing element constituting a body for electrodes, constituting a metal profile formed by interconnecting multiple tubes, containing a stiffness rib connecting adjacent ones from said profile tubes. Each profile tube comprises a vent located coaxially with said corresponding vent on the side surface of said collar part. The body for electrodes comprises electrodes rigidly fixed in each of the profile tubes, constituting metal tubes with equal linear capacity, but differing in length, wherein the main electrode is made of a length primarily equal to the length of the body for electrodes, and each compensation electrode is made of a length smaller than the length of the main electrode. The sensing element is configured to be connected with the base of the capacitance media interface level sensor through the holes for the mounts of the sensor body. The main electrode and each compensation electrode are configured to be connected with the electronic computing unit of the capacitance media interface level sensor by means of metal rods connected with embedded sleeves connected with the holes for the embedded sleeves of the sensor body.

EFFECT: increase in the reliability and manufacturability of the structure and, as a result, increase in the accuracy of measurements of the media interface level.
