Uncertainty™ is an enterprise-level uncertainty management system that combines data from multiple applications in the Metrology™ suite to streamline the uncertainty process.
Uncertainty exists in every measurement. Values obtained are simply best estimates; the actual values could be greater or less due to a variety of factors, including instrument limitations, environmental conditions, and inherent variability.
Fiscal regulations require measurement uncertainty for custody transfer oil and gas systems to stay within limits of ±0.25%. Historically, demonstrating compliance with the regulations was a complicated process. Individual spreadsheets with complex bespoke calculations needed to be created for every metering station, and collating all the required data was an expensive, labor-intensive process.
By defining a baseline uncertainty and measuring deviations in real-time process data and equipment calibration data, it now becomes possible to derive a good estimate of the overall uncertainty of the measurement station in real time.
Uncertainty™ automatically combines data from multiple applications in the Metrology™ suite to streamline the uncertainty process. It can track installed equipment, schedule and perform calibrations and proves, and monitor real-time data, all with minimal input from the operator to ensure accurate and up-to-date uncertainty results.
By combining the uncertainty associated with each station with the real-time production totals and applying up-to-date market values, Uncertainty™ can identify potential losses and gains in terms of volume and dollar pricing. The result of these combined uncertainties can help with predictive maintenance and determining potential mismeasurements. This allows management to effectively deploy resources to address the areas with the most significant impact.
Uncertainty™ provides a clear view of system uncertainty, enabling organizations to manage and mitigate their overall measurement risk.
