PIPELINE SAMPLING SYSTEM AND METHOD

摘要

The present invention describes a sampling system and densitometer system for sampling fluids from a pipeline. A flow loop is set up which continuously collects fluid from the pipeline and then returns the fluid with a minimum fluid flow rate so that the fluid is representative of fluid flowing through the pipeline at the time of sampling. For each sample, pressurized fluid is taken from the flow loop and directed to a pressurized sampling chamber. The sampling chamber is then directed by gravity to an removable sample container, which may pressurized or unpressurized, in each sampling cycle.

1. A method for making a sampling system for taking samples from a pipeline, comprising:
providing a sample line is connectable to said pipeline for circulating pressurized fluid from said pipeline and through said sample line whereupon said pressurized fluid is returned to said pipeline; providing that a processor is programmed for operating at least one valve to allow fluid flow from said sample line to a sampling chamber and then closing said at least one valve with respect to said sample line; providing that said processor is programmed for operating said at least one valve to provide a flow path from said sampling chamber to a removable sample container; providing that said sampling chamber is connected to a sample discharge mechanism so that when said at least one valve provides said flow path to said removable sample chamber and said at least one valve is closed with respect to said sample line, then said sample discharge mechanism is operable to urge a respective sample into said removable sample container.
