Abstract
AbstractFlow measurement is an essential task to production management, well monitoring, custody transfer, and legislation matters for natural gas production plants. Differential pressure (DP) meters are an economically attractive and reliable alternative for gas flow measurements. On the other hand, wet gas flows occur due to the nature of processes, especially at upstream gas production. Although the performance of DP meters in single-phase flows measurement is well known and consolidated in the literature, for wet gas applications, the wetness produces a positive bias in the differential pressure, called over-reading, inducing an erroneous gas flow rate reading, if not corrected. Motivated to know and manage such over-reading, several authors have investigated this phenomenon, proposing empirical correlations to correct flow readings. In this work, the most relevant correlations are investigated, comparing their performance and limits of each one.KeywordsWet gasOrifice plateVenturiv-coneOver-readingDifferential pressure meters
