TANK FOR TRANSPORTING FUEL ,CONTAINING A CAPACITIVE LEVEL SENSOR OF THE INTERFACE OF MEDIA WITH A COUPLING 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. Tank for transporting fuel comprises one capacitive media interface level sensor; wherein the capacitive media interface level sensor comprises a base; a sensing element of the sensor; wherein the base comprises: a first part containing a niche with a cover for tightly placing an electronic computing unit and a hole for the output cable of the electronic computing unit. A second part with: holes for embedded sleeves primarily in the centre in the area of the first part; fastener holes on the side surface; vents on the side surface. The sensing element of the sensor constitutes a body for electrodes, constituting a metal profile formed by interconnecting multiple tubes, containing a stiffness rib connecting the adjacent of said tubes of the profile. Each tube of the profile comprises, on the side thereof adjacent to the measured medium, a slot aligned with said corresponding vent on the side surface of said collar part along the axis. 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 of the sensor is connected with the base through fastener holes. The main electrode and each compensation electrode are connected with the electronic computing unit by means of metal rods connected with the embedded sleeves connected with the holes for embedded sleeves.

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.
