摘要
A system (100) includes a control system (138) and a field device (200). The control system is configured to communicate data with the field device. The field device determines whether a deviation in a measurement accuracy of a first characteristic curve for a flow profile of a process fluid is detected while monitoring an inline condition of the process fluid (520). The field device determines whether the deviation is greater than an application tolerance (525). The field device also performs an inline recalculation for a new characteristic curve according to present flow condition detected in measurements of the flow profile when the deviation is greater than the application tolerance (540). The field device calculates a flow rate of the process fluid using the new characteristic curve (560).
