Sources ofUncertainty
Uncertainty can arise due to many factors, such as poor systemdesign or equipment selection, incorrect installation, pooroperation and maintenance or general wear and tear.
Ameasurement systemmay have always providedmeasurementsthat, within an accepted tolerance are repeatable. This does notmean that the measurement is accurate.
Emerson Process Management, one of the eight brandplatforms of Emerson, is a leading global supplier of products,services and solutions that measure, analyse, control, automateand improve process-related operations. The company evolvedfrom the business previously known as Fisher-Rosemount, whichwas already a recognised leader in process-automation productsand technology.
As Emerson Process Management, we now offer even broadercapabilities to help customers control, connect and manage theirprocess and business. Specifically, we've augmented our best-in-classmeasurement, analytical and control products, and innovativePlantWeb® architecture, with a broad array of engineering,consulting, maintenance and projectmanagement services.
From our offices, factories and service centres around the world,our team now offers unmatched capabilities to improve processand asset performance for customers in the chemical, oil and gas,pulp and paper, pharmaceutical, food and beverage, power,waterand wastewater, and other process-related industries.
Process Solutions, one of the divisions of Emerson ProcessManagement, offers a broad array of engineering, consulting,project management and professional services to improveperformance for industrial and process customers.
METCO Services, operating within theProcess Solutions division of EmersonProcess Management, is a leader in thesupply of flow measurement services andsolutions.We are registered with First PointAssessment under registration number10040967 and are also registered withAchilles under registration number 76564.

So what assistance can you expect from METCO in managing the risk of uncertainty?
Quantifying the costs of uncertainty
Once the measurement uncertainty is known it is possible tocalculate the cost of the uncertainty. However this is purely afinancial measure and does not take into account the potential
damage to a company’s reputation if it has been proved they haveprovided short measures.

Points of uncertainty
Anywhere that hydrocarbon orrelated products are measured forvaluation or allocation purposes addsan area of uncertainty. Throughoutthe supply chain potentialmis-measurements accrue resultingin millions of dollars in possiblelost revenue or the overpaymentof duties.
Hydrocarbon producers, transportersand processors measure productflowing into and out of their pipelinesfor valuation or allocation purposes.These measurements are criticalbecause they directly impactprofitability. If measured too low,product is being given away, ifmeasured too high customers arebeing short-changed potentiallydamaging reputation.
All of these measures are subject toerrors that are ultimately expressedas UNCERTAINTY.
In order to maximise profit it isnecessary to manage uncertainty.
Review measurement systems, operations and production reporting, advising areas thatcontribute to uncertainty and making improvement recommendations.
