METHOD OF LIQUID SAMPLING FROM PIPE-LINE AND DEVICE FOR ITS REALIZATION

摘要

FIELD: oil and other branches of industry. SUBSTANCE: device according to method executes connection of pipe-line with automatic sampler by means of conduit. Point samples are taken from this conduit. Portion of liquid from conduit is periodically fed into automatic sampler eluding sample collector to ensure required hydraulics on moving members of automatic sampler while it operates. Then liquid is forced out of automatic sampler. Portion of liquid forced out of automatic sampler and not fed into sample collector is guided directly into pipe-line escaping conduit from which samples are taken. EFFECT: obtainment of more representative samples, execution of accurate quantitative analysis of liquid pumped over pipe-line. 2 cl, 2 dwg, 1 tbl
