Flow measurement compliance.

Assessing and certifying your flow measurement system's performance.

System compliance.

Leading audit services delivering assured performance and certified compliance.

A key challenge for international and national oil companies and metering system integrators is to ensure that their existing or proposed metering system is fit for purpose.

Errors in your measurement system can have contractual and regulatory implications resulting in dispute, litigation and reputational damage. It can also impact your bottom-line.

Utilising the latest in connected technologies, all compliance and assurance services can be delivered remotely.

Assured performance.

Proactively identifying current and potential issues – whether at a design, integration, commissioning or operational phase – Kelton’s Audit Services give you the assurances you need in your flow measurement system; ensuring ongoing performance and compliance.

Accurate from the start.

Kelton delivers a range of project support, including engineering studies, across all stages of a flow measurement system’s development.

From conceptual study and front-end engineering and design (FEED) through to factory acceptance testing (FAT) and site acceptance testing (SAT), you can be assured of system suitability prior to costly implementation.

Certified compliance.

As a United Kingdom Accreditation Service (UKAS) accredited inspection body, Kelton will fully assess your measurement system – regardless of the stage in development – and can issue a measurement compliance certificate in line with ISO/IEC 17020 upon successful audit completion.

This proves to all stakeholders that you have selected appropriate equipment, it is operated and maintained sufficiently to provide the best uncertainty of hydrocarbon measurement, and it conforms to the relevant standards, guidelines and commercial agreements.
