FUEL STORAGE TANK CONTAINING ONE CAPACITIVE MEDIUM INTERFACE LEVEL SENSOR 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, and can be used in various branches of industry. Tank for fuel storage comprises one capacitive media interface level sensor containing a base, a sensing element of the sensor. The base contains a first part and a second part. The sensing element of the sensor constitutes a body for electrodes, constituting a metal profile formed by interconnecting multiple tubes. Each tube of the profile comprises a vent placed coaxially with said corresponding vent on the side surface of said collar part, and on the side thereof adjacent to the measured medium comprises 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 tubes of the profile, constituting metal tubes with the same linear capacity, but different in length. The main electrode is made with a length primarily equal to the length of the body for electrodes, and each compensation electrode is made with a length less 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 embedded sleeves connected with the holes for the embedded sleeves.

EFFECT: increase in the reliability and accuracy of measurement of the media interface level, as well as provided possibility of measuring the interface levels of liquid media with different dielectric permittivity without the need for additional calibration of the capacitive sensor.
