Abstract
A method includes obtaining actual flow measurements generated by a flow meter, where the actual flow measurements identify a flow of material in a passageway. The method also includes generating estimated flow measurements based on process variable measurements other than the actual flow measurements. The method further includes comparing the estimated flow measurements and the actual flow measurements and determining whether a problem exists based on the comparison. The estimated flow measurements could be generated using one or more models mathematically representing how the flow of material in the passageway relates to non-flow process variables associated with the process variable measurements. The process variable measurements could be obtained from one or more sensors associated with a flow restrictor in the passageway, one or more sensors positioned within the passageway, and/or one or more sensors positioned outside the passageway.
