METHOD FOR MEASURING INTERFACE LEVEL USING A CAPACITIVE INTERFACE LEVEL SENSOR Russian patent published in 2023 - IPC G01F23/26 

FIELD: measuring technology.

SUBSTANCE: invention is intended for c the levels of interfaces between media in various industries. A method for measuring the level of the interface between media using a capacitive sensor for the level of the interface between media, in which the sensor is calibrated to obtain calibration values of the difference between capacitances and values of the dynamic range of the level of the interface between media recorded in the memory of the computing unit, using the reference measured medium. The level is measured using a calibrated sensor, and the measurement consists in performing stages, namely, filling the container with the measured medium to a level at which the longest compensation channel of the sensor is partially immersed in the measured medium, while the measured medium differs from the reference one, or filling the container with the reference measured medium to any level allowed for this container. The capacitance values of the main and each compensation measuring channel of the sensor are measured for the container containing the measured medium, with each measurement of the capacitance value of each compensation measuring channel is carried out taking into account the average correction factor.

EFFECT technical result is an increase in reliability, manufacturability of the design and an increase in the accuracy of measurements.
