Proving and certification tests of automatic sampling systems for custody transfer

摘要

An automatic sampling system can be tested to verify the equipment, installation and operational procedures produce a representative sample of shipments or batches. The test is called a sampling system proving test. The purpose is to validate the entire sampling system, including the analysis of the sample. This paper will deal with the testing ad proving of automatic sampling systems in crude oil service, although the proving test, in various forms, is also applicable for petroleum products as well as petroleum blending systems.
