Crude measurements require tight control

Uncertainties exist in net test results for measurement systems, caused by disparities in the measurement of water content and density. Poorly mixed pipelines, poor density measurement loops, and poor application of sampling technology create these uncertainties.These errors may not lead to real physical losses. But if the potential for such losses exist, it is imperative that both the defined ends of the measurement chain apply technology with the least possible uncertainty to eliminate their process from any disputes.Piecemeal improvement in measurement consistency is unlikely to lead to reduced uncertainty. All systems installed should be subject to a proving test of preference meeting...
