DEVICE FOR THE LIQUID MEDIA SPECIFIC ELECTRICAL CONDUCTIVITY MEASUREMENT Russian patent published in 2018 - IPC G01R27/22 

FIELD: measuring equipment.

SUBSTANCE: device is designed to measure the seawater specific electrical conductivity directly in the medium and can be used for measurement in other liquids. Summary of invention is in that the liquid media specific electrical conductivity measuring device contains a sensor with a non-electrically conductive disk, two current and n potential electrodes, a current generator, a commutator, a disk temperature resistive sensor, a resistance meter, a voltage meter and a microprocessor, at that, the fluid specific electrical conductivity is determined by the formula

,

where – fluid specific electrical conductivity between the i-th and j-th potential electrodes isolines; I is the current in the measuring cell; U_ij is the voltage between the i-th and j-th potential electrodes;

– ij-th pair of potential electrodes "geometric constant" value; n is the potential electrodes number; N is the number of the potential electrodes used pairs.

EFFECT: technical result is the improvement in the long-term measurement accuracy in the medium particular point.
