AUTOMATIC GAS ODORISING SYSTEM Russian patent published in 2014 - IPC G05D11/13 

FIELD: chemistry.

SUBSTANCE: gas odorising system comprises a main 1 and a control 2 container with an odorant, a feeding device 3, a control unit 8 connected to a power supply 10, said control unit being connected to a flow meter 6 of a main gas pipeline 13. According to the solution, the feeding device is a working chamber 14 in which there are at least three high-voltage electrodes 15, 16, 19 with controlled spacing, one of which 19 is earthed and the others are connected to the control unit, an inlet valve 11 connected to the main container, an outlet valve 12 connected to the main gas pipeline. The odorising system also includes, connected to the control unit, a pressure sensor 4 inside the working chamber and a pressure sensor in the main gas pipeline before the flow meter in the gas flow direction.

EFFECT: faster dosage adjustment and therefore accuracy of maintaining concentration of odorant in natural gas while reducing odorant consumption and improving safety.
