Flow measurement uncertainty.

Ensuring performance with proven calculation models to assess and validate system uncertainty.

System assurance.

The uncertainty experts.

With extensive experience in flow measurement uncertainty – including involvement in the development of national and international uncertainty standards and guidelines – Kelton's System Assurance services give you certainty in your uncertainty assessment.

Managing your uncertainty.

Providing uncertainty models for flow measurement, allocation and transportation systems, Kelton will assess your system's uncertainty to ensure it meets the required standards.

This includes: ensuring accuracy within flow computers, control systems, allocation systems and other business reporting systems; verifying flow data integrity from meter to reporting; and assessing the uncertainty levels in the reported totals used for contractual and regulatory purposes.

Resolving your uncertainty.

If there is a discrepancy between the stated and actual uncertainty, Kelton can advise on the right solution to meet your operational and commercial objectives whilst remaining compliant with all relevant contracts and regulations.

Furthermore, Kelton's consultancy experts will model the impact of changing equipment conditions, process conditions and other parameters on system uncertainty to support effective decision-making.

Uncertainty verified.

As a UKAS accredited flow measurement inspection body, Kelton can independently verify that your data integrity and uncertainty levels are appropriately maintained. This proves to stakeholders that all reported totals are accurate and within the stipulated limits, and demonstrates adherence to commercial and regulatory requirements.

The uncertainty challenge.
It's not just about compliance.

Demonstrating the uncertainty of a measurement system is a contractual and regulatory requirement.  But understanding and controlling your uncertainty is about more than compliance.

Optimising the value and efficiency of energy operations is key to achieving a better balanced and low-carbon energy future.  Better control of your uncertainty provides a better assessment of your energy operation’s efficiency and performance.

Supporting your uncertainty modelling.

UncertaintyPlus removes the uncertainty from your uncertainty assessment by enabling designers, flow measurement engineers and operators to determine the estimated uncertainty of a flow measurement system for a given set of operating conditions.

Furthermore, it will validate and prove the actual uncertainty performance aligned to the required standards.
