MODE AND A SYSTEM OF MARKING AND DEFINITION OF IDENTITY OF LIQUID HYDROCARBONS Russian patent published in 2007 - IPC G01N33/22 G01F1/704 

FIELD: the invention refers to measuring technique.

SUBSTANCE: the system of marking of hydrocarbon fluid medium running from the source to the designated place has at least one sensor for definition of at least one property of the flowing medium, at least one regulator of consumption of the marker for intake of the prescribed quantity of the marker into the flowing medium at least from one source of the marker. The property of the flowing medium is chosen out of the group including temperature, consumption, viscosity, density and concentration. A processor is switched at least to one sensor and at least to one regulator. The processor defines the prescribed quantity of the added marker (diluted in this case) in correspondence with the property of the flowing medium and the prescribed concentration of the marker in the flowing medium and controls the regulator of at least of one marker. The invention allows to identify oil. petrol, kerosene, different kinds of fuel for evaluation of conservation of the initial quality(dilution, falsifications) of the spill or leakage of liquid hydrocarbons from pipe-tubes, tankers or storehouses.

EFFECT: identifies different kinds of liquid hydrocarbons.
