During Oil & Gas production, crude oil, and natural gas flow from individual wells to manifolds, trunk lines, separators, dehydrators, and export lines, etc., before they reach processing facilities. To control the movement of hydrocarbons in the system, conventional meters are designed for the various stages of the process. As instrumentation ages and process conditions change, measurement errors and balancing discrepancies occur that ultimately impact efficiencies and cash flows. FLEXIM's clamp on flow FLUXUS meters are the perfect solution to assess the performance of outdated instrumentation, perform temporary monitoring of lines where there is no flow metering and ultimately replace outdated or out of service instrumentation without any pipework modifications required.
