METHOD AND DEVICE FOR REMOTE DETECTION OF GAS LEAKAGE PLACE WHEN PERFORMING AUTOMATIC SAMPLING Russian patent published in 2000 - IPC

FIELD: maintenance of apparatus and gas lines of chemical, petroleum-chemical, metallurgical and other production. SUBSTANCE: permanent action gas-sensitive facility is moved by controlled air-transport way to height of places of expected leakages. Leakage place is localized by change of indication caused by variation of surrounding gas concentration. Sampling is performed automatically when surrounding gas concentration reaches preset operation threshold corresponding to occurrence of leakage. The device for method realization is positioned on balloon and provided with pump automatic switch-on system and electronic circuit of indication of surrounding gas concentration. Electronic indication circuit may include potentiometer. EFFECT: reduced contamination of environment, enhanced safety. 3 cl, 3 dwg
