ABSTRACT:
An isokinetic sampling method has been discovered for use in a pipeline carrying a three phase mixture of petroleum, water and gas. The method is used in combination with a fluid fraction measuring means capable of measuring physical characteristics indicative of fluid fraction. A statistically significant number of samples is analyzed over the range of sampler flow rate. The sampling flow rate is reset to correspond with the flow rate of the maximum standard deviation sample. As a result, samples most representative of the pipeline fluid fraction are withdrawn.
